GradeShift Pro 2
Wireless 4G dual-path signalling at any grade, with unrivalled management tools. Our dual-path signalling solution utilises a combination of two Radio paths or one Radio and one LAN path to signal an alarm. Each SIM operates on an independent network from the other for total resilience. GradeShift Pro 2 is also compatible with CSL Live and the My Base App.
GradeShift Pro 2 Radio/Radio uses two active 4G WorldSIMs, each with its own radio module, one as the primary and one as the secondary path. A third standby SIM acts as a backup to the primary SIM on the primary path. GradeShift Pro 2 LAN/Radio uses LAN connectivity for its primary path and a 4G WorldSIM as its secondary path. A standby WorldSIM is also supplied.
Quick Guide
Introduction
The DualCom Pro 2 Range offers Installers easier, faster installation of a professional signalling system with even greater resilience, plus access to CSL Live, our ordering and management portal.
Using the onboard serial connections, pins triggering or dial capture, DualCom Pro 2 is compatible with a wide range of control equipment including systems installed to EN50136 & PD6662. The range consists of DigiAir Pro 2 – our single-path solution that utilises a Radio path or LAN to signal an alarm; and GradeShift Pro 2 – our dual-path solution that utilises a combination of two Radio paths or one Radio and one LAN path to signal an alarm.
It’s as Easy as 1, 2, 3

Step 1 - Site Survey
Variants with Radio
Use a CSL Signal Analyser to determine if enough base stations (2 or more) are available at the site and that they can supply sufficient signal strength (30% and above). This will determine the optimum location for the DualCom’s aerial to be mounted.
If you do not have a Signal Analyser we recommend powering up the DualCom Pro 2, connecting the aerial/s, going through the commissioning process and checking the signal strength before permanently fitting the aerial. Whilst in the connectivity menu, LED 1 (for single radio systems) or 1 & 2 (for dual radio systems) should be green to show an acceptable level of Radio signal/quality. See Connectivity LED section for more information see Section 4 – Testing (Figure 11).
Variants with LAN
DualCom Pro 2 uses DHCP as default, fixed IP settings can be added/amended in the My Base App. Fit the Ethernet Cable to the device and connect to the customer’s router. Ensure the customer’s LAN socket is live and their network allows access to the CSL servers – the CSL Live section has more information about what is required.
The ETH LED will flash green to indicate connection.
Step 2 - Installation
DualCom Pro 2 must be installed within an enclosure suitable for the installation certification. The unit should be fixed securely using the adhesive pads supplied or via the screw fixings accessible by removing the lid.
Once fitted, ensure:
a – As required, the aerial/s are connected and/or the ethernet cable is installed
b – The alarm panel or PSU is powered down, then wire the DualCom Pro 2 in this order.
1. Neg (-) power , 2. Pos (+) power , 3. serial cable or inputs
c – If required, connect the serial cable – RS485, RS232 or TTL (panel dependent) – see Section 3 – Commissioning (Figure 6) for more information
d – Connect any hardwired alarms into the device – see Section Technical Specifications (Figure 1) for more information
e – Connect the fault output
f – Ensure that all inputs are electrically isolated
g – Restore power to the alarm panel or PSU
IN ORDER TO MAINTAIN COMPLIANCE WITH THE REQUIREMENTS FOR ELECTRICAL SAFETY THE DUALCOM PRO SHOULD BE POWERED FROM A FUSED CONNECTION WITH FOLLOWING RATING:
- FOR A 12V DC SYSTEM (SUPPLY VOLTAGE IN THE RANGE 10VDC TO 14VDC) A FUSE RATED AT 1.25
- FOR A 24V DC SYSTEM (SUPPLY VOLTAGE IN THE RANGE 20VDC TO 36VDC) A FUSE RATED AT 600 MA
IF THE POWER SOURCE IS NOT LIMITED TO THESE VALUES, THEN A FUSE WITH THE CORRECT RATING MUST BE FITTED IN LINE WITH THE POSITIVE CONNECTION FROM THE POWER SOURCE
SITING AERIAL

MENUS & BUTTON CONFIGURATION
All device programming can be performed using the My Base App. We strongly recommend you use this App instead of the buttons and LED menu as it provides access to various hardware and site information. You can also use the one-time access page to install a device using your mobile phone or web browser even without login details. If you cannot get online during the install you can use the LED menu system and buttons.
LED MENU SYSTEM
Once commissioned, DualCom Pro 2’s menu system is divided in to 2 sections: Quiescent/Normal State and Connectivity.
BASIC BUTTON CONFIGURATION
To move between sections during installation press the A button. Whilst in quiescent/normal state, tap the C button to send a Test Call or Press and hold for 5 seconds to allow the device to perform a self-learn of the current input state.
Figure 3 – Quiescent/Normal state
LED 3 will show the device status.
- Green = paths and system are OK
- Amber = 1 path is not working
- Red = error
| LED 1 – N/A | LED 2 – N/A | LED 3 – Device Status |
 | | |
Press button A once in quiescent/normal state to enter this menu. LEDs 1 & 2 will show the signal/connectivity status of your paths.
LEDS BELOW SHOW FOR RADIO PATHS. ONCE PLUGGED IN, LAN CONNECTED DEVICES WILL SHOW GREEN = GOOD CONNECTION / AMBER = POWERED BUT NO DATA CONNECTION
• Solid green = good signal
• Flashing green = acceptable signal
• Flashing amber = emergency, only/low signal available (move aerial)
• Flashing red = SIM not ready/no signal available (move aerial).
• Red = error
Figure 4 – Connectivity
| LED 1 – Primary Path | LED 2 – Secondary Path (if Applicable) | LED 3 – N/A |

PIN TRIGGERING
For this operation the device is triggered by removing or applying zero volts to input terminals 1-12. No external pull-up resistors will be required. This is generally achieved via the digital communicator outputs of a control panel. On receiving an input to the pins terminals the unit will signal alarm conditions and will generate the relevant messages and forward them via the Gemini Global Platform to the ARC. Installers are advised that the intended use should avoid situations where the rate of trigger exceeds the rate at which messages are received at the ARC receiver.
Figure 5 – Example of pin triggering wiring
PIN INPUT CONFIGURATION
• To self-learn the current panel input status, press button C whilst in quiescent/normal state for 5
seconds. LED 3 will flash red twice once completed.
• To change the input from negative removed or applied to positive removed or applied, change the pin bias via My Base under the Hardware menu button and use the A+ terminal instead of RTN.
IF YOU CANNOT CHANGE THE PANEL’S POLARITY AND YOU DO NOT HAVE ACCESS TO MY BASE OR THE WEBSITE, PLEASE SPEAK TO OUR TECHNICAL SUPPORT TEAM
DualCom Pro device general inputs are defined as SIA untyped alarms for pins 1-12 (excluding pin 4).
UA/UR8001 to 8012 on standard product configuration.
Example: [#123456|NUA8001|AChannel 1 Alarm]
[#123456|NUR8001|AChannel 1 Restore]
DualCom Pro device pin 4 Open / Close inputs defined as SIA alarm OP and CL
OP/CL8004 on standard product configuration.
Example: [#123456|NOP8004|ASystem Set]
[#123456|NCLR8004|ASystem Unset]
OUTPUTS
All 3 outputs can be configured as either N.O or N.C as required. Output 1 is defaulted to indicate a total path fail condition to the control panel. Output 1 can be reconfigured to indicate another path failure type, Output 2 can be configured to indicate a path fail condition or be used as a manual trigger and Output 3 can be used as a manual trigger. To make any amendments please use the My Base App.
IF THE DEVICE IS POWERED BY A 24V (FIRE PANEL), THE + TERMINAL SHOWN WILL STILL DELIVER 12V
Figure 6 – Example of Fault Output Wiring
DIAL CAPTURE
DualCom Pro 2 simulates and replaces the phone line connection to the control panel’s Digi-Modem. The control panel’s Digi-Modem must use one of the following alarm formats: Fast Format*, Contact ID or SIA. In the event the control panel needs to send a signal to the ARC, DualCom Pro 2 will capture the message and forward it, via Gemini, to the ARC. The Digi-Modem must have an ARC telephone number (ie 01) and account number (ie 1234) programmed for Dial Capture to work. If you want to monitor the Dial Capture connection, you will need to connect an output configured as PSTN line fault on your control panel, to one of the DualCom’s inputs. That input then needs to be designated as Dial Capture Fail at your ARC.
*Please confirm compatibility of Fast Format with DualCom Pro 2 via your ARC.
Figure 7 – Dial Capture Wiring

Step 4 - Testing
Before leaving site you must test the DualCom Pro 2 device as per these steps.
a – Place device on test at the ARC and send a range of signals from the panel
b – Perform a path test by tapping button C whilst in quiescent/normal state
c – LED 3 will flash to show signals are being sent
d – Check signals are received at the ARC
You should also simulate path failures at part of the testing process.
a – Place device on test at the ARC
b – Whilst in the quiescent/normal state section, press button A to get to the connectivity menu. The LEDs (LED 1 = single-path, LED 1 & 2 = dual-path) will be lit
c – Hold button B for 5 seconds. Once let go, LED 1 will go red to show path 1 is in simulated fail
d – For dual-path devices, hold button C for 5 seconds. Once let go, LED 2 will go red to show path 2 is in simulated fail. Check signals are received at the ARC
e – Tap button B & C to restore each path. LEDs 1 and/or 2 will go green. Check path failure signals are received at the ARC
IF YOU HAVE PURCHASED A DUAL-PATH DEVICE, YOU MUST ENSURE BOTH PATHS ARE CONNECTED BEFORE LEAVING SITE.
IF YOU DISCONNECT BOTH PATHS AT THE SAME TIME, MY BASE WILL ONLY SHOW THE FIRST PATH IN FAILURE. THIS IS EXPECTED BEHAVIOUR.
LEDS & TROUBLESHOOTING

RADIO TROUBLESHOOTING
How can I fail my signalling paths without having to disconnect them?
To fail each path enter the connectivity menu (see simulate path fail section – Figure 12 above). Press and hold B to fail the primary path or C to fail the secondary path. The path will stay in fail for 15 mins unless you tap B or C again to restore the applicable path.
How can I check the signal strength of each radio module?
You can check the signal strength of each radio module on a commissioned device via the My Base App. Alternatively, when in the quiescent/normal state, you can press button A to toggle to the connectivity menu. Once there, LED 1 (first path) & LED 2 (second path) will show you the signal strength. We recommend a solid green LED (40% or 4/10).
Does my unit have a roaming SIM?
Yes, all DualCom Pro 2 devices come with at least 2 Roaming 4G SIMs
My signal strength is less than 30% (3/10) or my LED is orange/red. What can I do to improve it?
For all radio variants:
• Avoid coiling the aerial cable
• Move the aerial away from electrical equipment/wiring
• Move the aerial to a higher point in the property or closer to a window/door
Fire Guide
DualCom Pro Fire Guide
This document covers the requirements of a Fire installation and is a supplement for the GradeShift Pro 2 and DigiAir Pro 3. The guide uses DualCom Pro Fire to refer to both product variants.
Mounting
The enclosure requirements for the DualCom Pro Fire are the same as for the Fire Alarm Panel itself which must meet the requirements of the EN54-21 standard.
The DualCom Pro Fire should be mounted inside the Fire Alarm Panel or inside a separately powered housing that meets the requirements of section 7.3 of the EN54-21 standard.
Input Pins
The default pin profile configured at installation is “PinLearn Fire”. With this, pins 1 and 2 are configured for use with fire alarm panels (EOL mode) and will generate a SIA Tamper Alarm/Restore in response to additional conditions along with Alarm and Restore with the other pins:
Open circuit and open circuit restore
Short circuit and short circuit restore
Fault
If additional pins are required in EOL mode, use My Base to configure the DualCom Pro Fire to use pin profile “PinLearn EOL Pins 1-12”. In this configuration all pins on the DualCom Pro Fire will respond to the additional conditions and generate the corresponding events to the Gemini Global Platform.
Pin 1: intended for receiving the Fire Alarm/Restore signal from the Fire Alarm Panel.
Pin 2: intended for receiving Fault/Restore signal from the Fire Alarm Panel.
Remaining Pins: used for receiving notifications from any other device (e.g. an Intruder Panel). These pins take a lower priority than pins 1 & 2 when signalling to the Gemini Global Platform.
Input Pin Wiring
Input pins, which are configured in EOL mode, require 10k and 4k7 Ohm resistors to be wired in line as shown below.
The DualCom Pro Fire uses a normally closed configuration so that a power fail on the Fire Alarm Panel will signal an alarm to the Gemini Global Platform.
If the circuit is broken, then an open circuit tamper alarm will be generated
If it detects 0v, then a short circuit tamper alarm will be generated
If the wrong resistor values have been used, then a fault tamper alarm will be generated
Resistors
These are the colour code markings for the 10k Ohm and 4k7 Ohm resistors respectively.
Self-Learn
If the self-learn functionality (Press Button C for 5 seconds) is invoked when an EOL pin is Alarm State then the DualCom Pro Fire will switch to generating a Restore event when a high voltage is detected for that pin going forward and an Alarm event when a low voltage is detected.
Relays
The relays are intended to notify the Fire Alarm Panel of events on the DualCom Pro, Gemini Global Platform or from the ARC. Their configuration is fixed in Fire Mode and cannot be changed via My Base.
When the DualCom Pro is unpowered, NC is connected to C and NO is not connected to C.
When the DualCom Pro is powered and in a quiescent state, Relay 1 has the NO1 connected to C1 and the NC1 is not connected to C1.
If a fault occurs then, Relay 1 changes such that NO1 is not connected to C1 and NC1 is connected to C1. When the fault is cleared it will revert.
Fault conditions include:
- If any of the input pins being monitored enter a fault state
- If there are communication path issues (Line Fault)
- If there is an alarm/restore that is sent to the ARC for one of the monitored pins and a response is not received within the configured timeout
- If there is a power failure
Relay 2 will connect NO2 to C2 and disconnect NC2 from C2 relay for 5 seconds to indicate that the ARC has acknowledged successful receipt of an event.
Relay Wiring
Fault Reporting
To meet the EN54-21 requirements for monitoring on Type 1 Fire systems, this device sends regular polling calls to the Gemini Global Platform on all connected and active transmission paths. The Installer shall ensure that appropriate reporting actions have been agreed with the ARC for all alarm codes, transmission path failure notifications and polling failure reports from the Gemini Global Platform.

To fail each path enter the connectivity menu (see figure 12 on Quick Guide). Press and hold B to fail the primary path or C to fail the secondary path. The path will stay in fail for 15 mins unless you tap B or C again to restore the applicable path.
How can I check the signal strength of each radio module?
You can check the signal strength of each radio module on a commissioned device via the My Base App. Alternatively, when in the quiescent/normal state, you can press button A to toggle to the connectivity menu. Once there, LED 1 (first path) & LED 2 (second path) will show you the signal strength. We recommend a solid green LED (40% or 4/10).
Does my unit have a roaming SIM?
Yes, all DualCom Pro 2 devices come with at least 2 Roaming 4G SIMs
My signal strength is less than 30% (3/10) or my LED is orange/red. What can I do to improve it?
For all radio variants:
– Avoid coiling the aerial cable
– Move the aerial away from electrical equipment/wiring
– Move the aerial to a higher point in the property or closer to a window/door
What is the standard pin setup of the GradeShift Pro 2?
As standard, the device is triggered by removing or applying zero volts to input terminals 1-8. No external pull-up resistors will be required. This is usually achieved via the digital communicator outputs of a control panel.
If you need to use a positive applied/removed, you can toggle the pin bias via the My Base app or contact technical support so that they can amend the bias of the device.
Can I use the onboard serial connection as well as pin triggering at the same time with the GradeShift Pro 2?
Yes, you can.
How do I carry out the pins self-learn feature on the Gradeshift Pro 2?
- Ensure all required pins are in a restore/quiescent state and you are out of the device menu.
- Whilst in Quiescent/Normal state, press and hold the C button for 5 seconds.
- LED 3 will flash red twice once completed.
How do I add a panel to my GradeShift Pro 2?
You can add a panel profile via My Base under the “Hardware” menu and select “Edit Panel”. Please note you only need to set panel 1 (please leave panel 2 blank).
If you are not sure which panel profile to select, please search the panel guide for your specific panel on the Support Zone as the guide will confirm which panel profile you need to select.
Why are pin alarms not coming through on the alarm log?
As standard, the device is triggered by removing or applying zero volts to input terminals 1-8. If you are using a positive applied/removed to trigger the pins, you will not see any pin alarms in the alarm log until the bias of the device has been changed.
To change the input from negative removed or applied to positive removed or applied, change the pin bias via MyBase under the “Hardware” menu and use the A+ terminal instead of RTN.
Alternatively, please contact technical support for assistance.
Why am I not receiving SIA signals from my panel?
Your device will come pre-configured without a panel connection type (pins only). To enable the serial connection to a control panel, go to MyBase and select the panel type. To do this, follow the below steps:
1. Go to hardware. Click on the options “hamburger” icon and select “edit panel”.
2. Select the correct panel type in panel 1 and then click on “save changes”.
3. Your device will upload its configuration and reboot. Once the reboot has taken place you should start receiving signals from the control panel.
If you are not receiving signals, make sure you have completed the panel programming steps detailed in the panel guide for that particular control panel.
Is it possible to invert the polarity of just one pin?
No, all pins either must be negative applied/removed or positive applied/removed. There cannot be a mixture of negative and positive.
How can I carry out a path test?
To perform a test of all paths, make sure your device is in Quiescent/Normal state and then tap the C button once. LED 3 will flash to show signals are being sent.
What is the standard setup of the GradeShift Pro 2 fault output?
All 3 outputs can be configured as either N.O or N.C as required.
Output 1 is defaulted to indicate a total path fail condition to the control panel (but it can be reconfigured to indicate another path failure type).
Output 2 can be used to indicate a path fail condition or be used as a manual trigger.
Output 3 can be used as a manual trigger.
To make any amendments please use the My Base app or contact technical support.
How do I know if my device has started to commission?
Once the device is powered-up, you should see activity on LEDs 1, 2 and 3. When the device has commissioned, all 3 LEDs will go green for 5 seconds. The device will then reboot.
Once the device has completed its commissioning process, only LED 3 (device status) will be active whilst in Quiescent/Normal state.
You can also check the status of your device on the My Base App.
Do I need to use the resistors provided in the box?
You should only use the resistors provided if the installation needs to be EN-54 compliant. If unsure, please check with your ARC.
Useful Information
Customer IT Survey Form
The Customer IT Survey Form may be required when ordering LAN + Radio or LAN only devices.
The DualCom Pro will require an IP address to be allocated to it by the customer’s network administrator.
Aerial Fitting Guide
WHEN COMPLETING AN UPGRADE OR REPLACEMENT ON AN EXISTING INSTALLATION, PLEASE ENSURE YOU ALWAYS USE THE AERIAL SUPPLIED WITH THE NEW DEVICE.
THIS WILL ENSURE THE BEST MOBILE SIGNAL FOR YOUR INSTALLATION. SOME OLDER AERIALS DO NOT PROVIDE ACCESS TO 4G AND, IF USED, COULD LEAD TO SIGNAL-RELATED ISSUES AND FAILURES.
We encourage you to complete the following steps to ensure your DualCom Pro achieves the best possible signal.
- Step 1 – Use a Signal Analyser to determine the optimum location for the aerial/s and follow the advice from the Signal Analyser section below.
- Step 2 – If you do not have a Signal Analyser, power up the DualCom Pro, connect the aerial/s, go through the commissioning process and check the signal strength before permanently fitting the aerial. We recommend a signal strength on the DualCom Pro of at least 3 (30%)
or above.
STEPS 3 & 4 ARE ONLY FOR IF YOU ARE FITTING A DUAL RADIO AERIAL.
PLEASE SKIP TO STEP 5 IF YOU ARE FITTING A SINGLE RADIO AERIAL.
- Step 3 – If you are using a dual radio product, make sure that both aerials are at least 2 metres apart.
- Step 4 – If using a dual radio product, position the aerials in a vertical orientation.
- Step 5 – Keep your devices’ aerial/s cables away from high voltage cables or any other aerial cables.
- Step 6 – Keep your aerial/s inan open space and 1 metre away from large metal objects or sources of interference (i.e. wiring, lighting, electrical installations, computers, control panels, fuse boards, routers, etc.)
- Step 7 – Do not tightly coil any excess aerial cable. Try and make large loops if possible.
See below for examples of good and bad single & dual aerial set-ups.

Output Controls
BACKGROUND
With the launch of DualCom Pro 2, Installers are now able to control the three outputs available on their device via My Base. This allows the Installer to configure the line fault output to their specific requirements, along with giving full control of the manual triggering of outputs 2 and 3.
Output controls will only appear on My Base for DualCom Pro 2 devices and any future variants. For the original DualCom Pro, Installers are only able to invert the line fault output.
OUTPUTS
Output 1 is for line failure reporting to the control panel. It can be configured to trigger in the following instances:
| Path fail – both paths | The line failure will be reported once both the primary and secondary interfaces are down for the given period allowed. This is the default for all dual-path systems. |
| Path fail – either path | The line failure will be reported once one of the primary or secondary interfaces is down for the given period allowed. It does not matter which interface is down. |
| Path fail – primary path | The line failure will be reported once the primary interface is down for the given period allowed. The status of the secondary interface is not reported in this mode. This is the default for all single-path systems. |
| Interface status mode | Do not use – This is for future use |
| None | Output 1 is disabled |
Output 2 and 3 are used for manually operating an output. This can be used for controlling electronic equipment, such as remotely opening gates/garage doors, resetting routers, turning on/off lights, etc). Both outputs 2 and 3 can be set to the following:
| Manual | Upon clicking the N.O or N.C button, the output will change state. |
| None | Output 2 or 3 is disabled. |
OUTPUT LABELS
Each output can be labelled individually to ensure Installers do not need to remember which output operates each function.
To edit the output name, click on the edit icon 
. To change the text, you must overtype the existing text and click 
. You can exit renaming by pressing 
.
Example of renaming outputs:
MANUAL TRIGGERING (LATCHING)
Once output controls are selected within My Base, the status of each output will be updated and shown to the user.
To trigger the output, ensure that the relevant output (2 or 3) is set to ‘manual’ and click on the N.O/N.C button. Clicking the button will invert the output from its current state, and stay like that until the button is clicked again (this is called latching).
It is not possible to pulse the output for a period. This is where the output inverts for a given period (e.g. 1 second) and reverts to its original state once the timer has expired.
Example of output control screen:

PinLearn EOL Pins 1-12
Enables DualCom Pro devices to monitor all pins in EOL mode rather than just pins 1 and 2.
Traditionally in the UK, Fire panels have connected up pins 1 and 2 in EOL mode for the DualCom Pro to monitor.
Recent changes in legislation in Scotland have resulted in requests for additional pins to be monitored to allow, for example, Confirmed Fire to be communicated to the ARC. This new pin profile enables the Installer to configure the CSL DualCom Pro device to deliver this.
Usage
When purchasing a DualCom Pro Fire, it will be configured to use a pin profile of PinLearnFire. This and PinLearnFire No-A Block are configured to put pins 1 and 2 in EOL mode.
Pin Profile PinLearn EOL Pins 1-12 is configured to put all 12 pins on a DualCom Pro 2 and all 8 pins on a DigiAir Pro 3 into EOL mode.
This does not affect the monitoring for tamper and short circuit in Fire mode which, by default, is pins 1 and 2. If you require additional pins to be monitored for tamper and short circuit then currently this needs to be configured by Tech Support.
Similarly, output relay 1 will only trigger by default if pins 1 and 2 are triggered with. If an additional pin should trigger output relay 1 then this needs to be configured by Tech Support. Making this change will also result in any additional pins reporting ARC Ack on output relay 2.
Contact ID Alarm Protocol
The DualCom Pro range supports Intruder Panels using SIA, Fast Format and Contact ID protocols.
When integrating the DualCom Pro range with an Intruder Panel, our recommendation is to use either SIA or Fast Format (6.8.1, 6.16.1 or 6.32.1) protocols.
If Contact ID is to be used to pass events to the ARC, please be aware that it will only use the least significant 4 digits of the ARC account ID. The ARC must supply this prior to installation.
If the ARC does not support this then one of the other signalling formats should be used.
For reference, please see the below breakdown of a Contact ID alarm message constructed from several fixed length message blocks.
These are defined as follows:
18AAAAQXYZGGCCC
Where:
18 – Contact ID type identifier.
AAAA signalling ID – 4-digit account number.
Q – Event type – E (new alarm event), R (new restore event) or P (previously reported alarm).
XYZ – Event number – Defines the type of event that has occurred.
GG – Area number – Set to 00 if no areas defined.
CCC – Zone or User Number – Dependent on the type of event defined by the event number.
This fixed length account number field restricts the required 6-digit account number entered in the intruder panel being presented to the Alarm Receiving Centre. Resulting in events being misinterpreted.
