There is a small amount of additional telematics software required to set up a DigidownT. To assist with this, a DigidownT development kit is available. Please contact us for more details.

The DigidownT uses the existing telematics connection, so does not require a separate SIM card. The DigidownT will send files over the telematics connection, however these are relatively small. The extra data required by the DigidownT will depend on the frequency of tachograph downloads.

On the rear of all standard digital tachographs there are four 8-way connectors. These are easily identified by their colours:

• Connector A is white and provides power to the tachograph. It is also used for CAN1, the main control bus for the vehicle. For safety and good operation of the vehicle, the DigidownT does not use CAN1. However, a connection to this plug may be required to power the DigidownT for use with Bluetooth or WIFI connections.
• Connector B is yellow and connects to the speed sensor in the gear box. DigidownT does not use this connector.
• Connector C is red and contains CAN2, the secondary vehicle control bus. This is expressly provided for remote downloading and is isolated within the tachograph. Activities on CAN2 cannot affect the operation of the vehicle. This is the primary connection used by the DigidownT.
• Connector D is brown and provides some real time data that can be useful to collect.

The cable you receive with your DigidownT will connect to the red and brown slots on the back of the tachograph. A back-to-back white connector to connect the power is provided for Bluetooth and WIFI versions.

If you discover other devices plugged into the red or brown connections, or some other connection situation, please contact us and we can provide you with appropriate cables.

Depending on requirements, the DigidownT can connect to your Telematics system via

• Wired connection - custom cables available on request
• Bluetooth
• Wireless LAN (WIFI)

Contact us to discuss your options.

Please see our DigidownHost User Guide. If you have not been provided with DigidownHost software, please contact us.

The files downloaded by the DigidownT are passed to the vehicle telematics system. The sending of these files is controlled entirely by the telematics system.

The DigidownT is a remote downloading device, therefore can only be used with tachographs where this has been enabled. Tachograph versions VDO 1.3 and later, and Stoneridge 7.1 and later with remote downloading options turned on are suitable for use with the DigidownT. Please ask your workshop or contact us if you are unsure.

The DigidownT provides access to the D8 tachograph real time data and various driver, tachograph and vehicle information when required.
