13.2 DLD and DTCO

The MiX 4000 also satisfies the need for Remote DTCO Download functionality by incorporating CAN, D8 and

K-line communication. The main functionality is the ability to remotely download DTCO data as well as the D8

status change for the Hours of Service solution.

This functionality allows the user to perform the following:

 Synchronise download schedules.

 Authenticate remote tachograph cards.

 Transfer downloaded files to back-office archiving systems.

 Receive updated firmware and configuration settings.

13.2.1 D-8

The D8-line is a free running data interface for fleet management systems. The DTCO information (like date,

time, currently selected driver and co-driver activity, hours of service, speed of vehicle, etc.) is sent on this

communication line. The receiving line of Serial Port 2 is used for the D8-line. The pin numbers of the serial

port are shown in sections 6.5.5. Connect to pin 2 (of Serial Port 2 on MiX 4000 PCB) to pin 8 of the brown

DTCO D-connector.

13.2.2 Connect CAN to DTCO

Refer to section 13.1 on CAN. One of the available CAN busses (normally CAN #2) can be routed to the

DTCO CAN. The Yellow and Green wires must be routed to DTCO C (red) connector pin 5 (Yellow/black)

(CAN-H) and 7 (Green/black) (CAN-L). See pictures below.

13.2.3 K-line

Connect the DTCO K-line to pin 13 of the Auxiliary 1 Harness (see section 6.5.2).

14 MiX TechTool

An Android and iOS version of “MiX TechTool” is available that can connect to the MiX 4000 via Bluetooth.

Refer to the documentation on this tool for detailed instructions.
