Installation guide: Heavy Trucks with RP1226 diagnostic harness on Fleet

This article explains how to install a device using an RP1226 diagnostic harness.

Time required: 20-40 minutes

Configuration file updates
1. Installation technicians must call Support to enable all installed accessory hardware, and apply its parameter settings. For example, a Driver ID and buzzer must be enabled along with parameter settings for the buzzer's grace period and time out settings by calling Support.
2. The configuration file must also be updated to enable white wire ignition detection if a 3-wire (hardwired) power connection is used (not applicable to RP1226).

Step 1: Identify the parts

RP1226 connector pin-out.

• The RP1226 has 14 connectors (2 rows of 7 connectors).
  
  
  
• Refer to the following pin out list for identification or troubleshooting:
  • Pin 1: Protected power
  • Pin 2: J1939 S-CAN (+)
  • Pin 4: J1939 K-CAN (+)
  • Pin 7: Ignition power
  • Pin 8: Ground
  • Pin 9: J1939 S-CAN (-)
  • Pin 11: J1939 K-CAN (-)

Step 2: Locate the RP1226 connector

The primary RP1226 connector is normally found just above the driver's side foot well. Some are freely accessible, while others require removing a kick panel to expose the RP1226 connector near a power distribution junction box.

Many trucks also have a secondary RP1226 connector behind the centre console panels. Secondary connectors can be located near the top beneath the "pie plate", or near the mid-line and lower right-hand side of the centre console.

Step 3: Mount the device

Devices are normally mounted behind the driver's side instrument cluster or knee panel, or beneath the top cover of the centre console. Devices are able to receive cell network and GPS signals without issue through glass, plastic, and most composites.

1. Secure the device to a bracket, stable wiring bundle or other flat surface using zip ties, VHB tape, or industrial strength Velcro so that it cannot move.
   The device must be fastened securely to prevent it from moving and generating erroneous harsh driving event reporting.
2. For best reception, mMount the device label-side up with a skyward-facing view and clear line of sight out of the vehicle.
3. Do not mount the device directly beneath large metal objects which can block signals.
   The device and harness must not interfere with the driver or normal operation of the vehicle. Pay special attention to pedals, steering shafts, telescoping steering wheels and adjustment levers.

Mounting location: Xirgo XT63xx

Step 4: Connect the hardware adapter cable

Plug the RP1226 diagnostic harness into the provided hardware adapter cable.

Step 5: Route the cables

1. Route the cables to the mounting location you chose earlier. Coil and secure any loose cabling using zip ties.
2. Double check everything is fastened tightly, and trim zip ties if they have excess length.
   Use caution trimming the zip ties. Accidentally cutting or nicking nearby wires will cause performance issues with the vehicle.

Step 6: Connect the ignition wire (optional)

The factory RP1226 harness provides battery+, ignition, and ground.

Ignition output is provided by the blunt-cut white wire coming from the universal RP1226 connector harness. This output can be used to supply power to cameras, or other accessories such as Driver ID buzzers, or panic buttons as needed, but is not required for all installations.

1. Use a butt connector, posi-tap, or crimp cap to join the ignition output wire to accessory item's ignition power line.
   
2. You must use a 3-5 amp fuse holder if the ignition output is connected.

Step 7: Connect the diagnostic cable end to the device

Plug the hardware diagnostic harness adapter into the device (see device images below).
