RS232 COM list and roles

H4 I/O 1 (blue harness)
COM0 (Black RS232*) : Free
COM2 (White RS232*) : C4C/H4 communication gateway

H4 I/O 2 (red harness)
COM1 (Black RS232*) : Free or H4 console
COM3 (White RS232*) : Free or SmartCardDriver if enabled (smartCardManager.active=1)

Installation (wiring)

H4-C4C (Serial)

1 C4C
2 C4C ground (black), permanent power (red) and ignition (white) wires
3 C4C COM1 ( white RS232)
4 C4C COM0 (black RS232)
5 H4
6 H4 ground (black), permanent power (red) and ignition (white) wires
7 H4 COM2 (I/O1 blue harness / white RS232)
8 H4 COM0 (I/O1 blue harness / black RS232)
9 H4 I/O1 harness (blue ring)

The C4C COM2 must be connected to the H4 COM2.

Note: Once devices are connected, the communication must be activated on both devices through the light/basics console : serialPPP.enableMultiBoard=1.

H4-Dreevo-M (USB)

1 Dreevo-M
2 Dreevo-M USB connector
3 H4
4 H4 H/D info cable

Once devices are connected, the communication must be activated on both devices through the light/basics console : usbMount.enableMultiBoard=1.

Note: A specific software deployment must be installed on both devices to enable the communication through the USB.

H4-Dreevo2 (Serial)

1 Dreevo2
2 Dreevo2 cradle with Molex connector
3 Dreevo2 cable with a male RS232 + digital outputs
4 H4
5 H4 COM2 (I/O1 blue harness / white RS232)
6 H4 power cable

Note: Once devices are connected, the communication must be activated on both devices through the light/basics console : serialPPP.enableMultiBoard=1.

FMS feature

The H4 must be connected to the FMS gateway 1 to retrieve CAN data. Please note that even if some truck vendors provide a specific FMS gateway, the H4 is able to retrieve CAN data through the standard CAN HIGH and CAN LOW signals.

We provide a sample module (fmsReader) which is able to retrieve the following data:

  • FMS total fuel used
  • FMS Fuel level
  • FMS axle location
  • FMS truck axle weight
  • FMS total engine hours
  • FMS vehicle identification
  • FMS software identification
  • FMS High resolution total vehicle distance
  • FMS next regular maintenance
  • FMS engine coolant temperature
  • FMS standard information

Compatible tachometers and wiring diagram

Green and yellow wires of the power cable are used to connect the H4 to a tachometer.

  • Green = TACHO INFO
  • Yellow = TACHO 4PPM
Tachometers H4 Wires Tachometer back connectors
1324 Yellow Not used
Green D8
1324_VOLVO(*) Yellow B7
Green D7
1381 Yellow Not used
Green D8 (Sometimes B8 is used instead of D8)
2400 Yellow Not used
Green D8
8400 Yellow Not used
Green D7
EGK100 Yellow B7
Green C1 (3963288 and 3963289) or C8 (3985693 to 3985700)
L2000 Yellow Not used
Green D8
SE5000 Yellow Not used
Green D8
  • Here is the list of supported 1324_VOLVO tachometers:
  • FT1324-513115180303
  • FT1324-713115230303
  • FT1324-513115210303
  • FT1324-523115170303
  • FT1324-713115220303
  • FT1324-723115200303

Once H4 and tachometer are connected it is required to apply a specific configuration with the correct tachometer type.

chronoTachyGraph.active=1
chronoTachyGraph.chronoTachyGraphType=X where X can be

1 for a CHRONO_1318
2 for a CHRONO_1324
3 for a CHRONO_1324_VOLVO
4 for a CHRONO_1381
5 for a CHRONO_2400
6 for a CHRONO_8400
7 for a CHRONO_EGK100
8 for a CHRONO_L2000
9 for a CHRONO_SE5000

Special requirement for ADR tachometers

If you want connect a H4 to an ADR tachometer you have to add a jumper on the JP1 connector.

1. Remove the front cover and release the PCB;
2. Look for the JP1 connector;

3. Add a jumper;
4. Replace the PCB and the front cover.
