Specifications
Electrical
The Tacholink 5 is fitted with internal self-resetting thermal fuses to limit current in the event of a fault. To protect the
vehicle against faults in the external wiring, the use of a 5A slow-blow fuse is recommended.
The Tacholink T5 Remote accelerometer acts as a transducer; sending all of it’s information across the
CANBus network to other device. The T5 RA does not store data or broadcast it wirelessly
Figure 5 - 3400134
Deutsch DT04
Remote Accelerometer
The Tacholink T5 Remote Accelerometer uses the same hardware platform as the Tacholink T5 EDR. Mount the T5 RA to
the vehicle using the same method as the T5 EDR. Both devices use the same power and J1939 connectors
To make full use of the internal accelerometer and gyroscope, the T5 must be firmly mounted with any of its axis
perpendicular to the direction of travel.
Caution
- Care should be taken when drilling into the floor of any vehicle as there may be
wiring or parts on the other side.
- When mounting on the driver’s side of the vehicle, it is extremely important to
ensure that the T5 is secured and cannot interfere with the safe operation of the
vehicle
- Do not expose the T5 or any of its peripherals to temperatures outside of 0°C -
80°C
Under Seat Mounting
Care should be taken when securing the T5 under seating in vehicles. Make sure the unit and its cables are properly
mounted away from any passengers and moving parts.
Cabinet / Panel Mounting
Although we design our equipment to operate in IP rated environments, we recommend when the unit is not installed
within the cabin of a vehicle that it be placed in a protected area. Avoid mounting equipment and cabling where it may
come in contact with moving parts and liquids as it will reduce its lifespan and reliability.
Different design configurations will change the IP rating depending on the front panel connectors. For more information,
contact Circuitlink.
Firmly secure the unit with bolts M5 or equivalent, using washers to distribute force evenly. Cable ties may be used for
temporary mounting and should be firmly tightened. Do not use double sided tape or any permanent adhesives.
Dashbox
Secure the Dashbox unit within the reach of the operator careful for it not to interfere with the operation of the vehicle.
Avoid placing the Dashbox where it could be exposed to weather as it does not have the same protection as the EDR.
T5 Standard External OBDII (PN 3400123)
The J1962 interconnect harness is designed to integrate with the existing diagnostic port and piggyback off it.
1. Locate and unscrew the existing connector from its mounting position. Typically it will be located within 1m of the
drivers position however may differ based on the make and model.
2. Connect the wiring assembly to the vehicles socket and mount the piggyback extension in the existing position.
3. Secure the connection between the vehicles J1962 socket and the harness by using a cable tie around the
housings.
4. Tidy cabling by securing excess wires away, careful not to kink or allow them to become tangled.
- The vehicle should be turned off when disconnecting any connectors on the T5
- Ensure when inserting the Samtec connector it is plugged in straight to avoid damaging the
fine pitched pins within the connector.
Warning
Only use cable assemblies described in this guide. Using assemblies for other models may damage the unit
and other equipment on the vehicle.
Warning
Do not place the PCB on any conductive or wet surfaces.
Where possible, follow steps to protect against ESD damage.
Improper removal of the face plate will compromise its IP rating and reliability of the device
1. Attach and firmly tighten the SMA connectors for the GPS, GSM and WIFI antennas.
When antennas are not in use it is recommended to keep the antenna attached or use (PN 3400139 - SMA plug cap)
to protect the connector from dust and water.
2. With power to the unit disconnected, connect the I/O cables from the unit to the vehicle.
Removing the Face Plate
For any reason you are required to remove the T5 from its housing either to change SIM cards or as directed by
Circuitlink, you must follow these steps. For best results, use PN 5991111611 available from Cinch.
1. With power to the unit disconnected, remove the I/O and antenna cables from the T5.
2. If possible, remove the T5 from where it is mounted as you need access to all sides.
3. With a small flat blade screw driver, gently release the one of the side tabs and let it balance without re-seating.
Starting from the top of the case, prise each of the tabs along the top, then along the bottom to release the face
plate.
4. Finally release the last side tab and gently slide the unit from the case.
5. When re-inserting the unit, make sure there are no internal wires caught and gently press the face plate back into
the housing making sure not to damage the rubber sealing gasket until all the tabs click into place.
Do not delete or modify the Device configuration file. This file is required for the device to operate
Configuration files use the .PV2 file extension. Fleet and Dynamic configuration files hold different variables for each
device.
Fleet contain parameters required to set how the data recorder operates. This can be anything from accelerometer
configuration to CAN/OBD packet settings.
The process and handling of configuration files in the EDR and Remote Accelerometer is different due to the differences in
firmware and flash storage architecture.
As the Remote Accelerometer is a transducer that does not store any data, the available storage to hold configuration files
is only a few kilobytes. Because of this, it will not hold multiple copies of the same file like how the EDR operates.
Event Data Recorder
The process for updating configuration is the same for all event data recorders regardless of the firmware version or
family.
1. Connect the T5 to power and allow it to boot up.
2. Connect a USB cable from the T5 to your PC
3. Open My Computer and navigate to the removable storage device with the label that of the T5
4. Place the desired configuration file in the PARAMS.
5. Disconnect the USB to reinitialise the device
Remote Accelerometer
The Remote Accelerometer will only hold one fleet configuration file in its internal storage at any time.
1. Connect the RA to power and allow it to boot up.
2. Connect a USB cable from the RA to your PC
3. Open My Computer and navigate to the removable storage device with the label that of the RA
4. Place the desired configuration file in the root of the drive.
The device will reinitialise and process the file. A status file will be present in the drive indicating if the update was
successful.
6. From the Communication menu, connect to the COM port for your unit as found in step 4.
7. If you have the configuration file available, you can populate the labels for each input by adding the
configuration file. For best results, this can be located by navigating to the PARAMS folder on the unit after
selecting the Add config file button in the menu. The T5 operating system is designed to select the latest
configuration file from this folder. The configuration file follows the following scheme : Fleet-YYYY-MM-DDHH-MM-SS.pv2
8. When you are finished with the utility disconnect the device by selecting Disconnect from the
Communication menu. If the device was removed without disconnecting it first, the serial port may remain
locked by the application. With the USB cable disconnected, close the Configuration Utility and restart the T5.
With power applied to the unit, reconnect the USB cable and launch the configuration utility.
