Wireless Link Receiver Installation Guide

Gather the following Samsara hardware, tools, and consumables before you install the receiver.

Complete these prerequisites before you select and wire a power source.

Evaluate receiver power sources in this order. Use a multimeter to confirm that the selected source is 12 V, cycles with ignition (unless you need parking-mode constant power), and shares the trailer ABS power path so PLC can reach the transmitter.

When earlier power options fail to create a link pair, some tractors include a filter between battery power and the 7-way. Power the receiver from the 7-way side of that filter, or from the side connected to the tractor ABS ECU, so both units share the same power domain. For debug steps, see Troubleshoot the Wireless Link.

Connect Power from the ABS Line

Use this option when earlier power sources do not establish a PLC link, including vehicles with a filter between battery power and the 7-way.

1. Identify the ABS ECU under the dashboard or elsewhere on the vehicle.

2. Identify the truck-to-trailer ABS harness.

3. Connect the CBL-CL-APWR red wire (power) to the 12 V ABS power wire, and connect the CBL-CL-APWR black wire (ground) to vehicle ground.

   When this connection is outside the cab, use a weatherproof installation method. Do not use positaps outside the cab.

4. Proceed to Mount the Receiver and Connect Video.

After you select and wire a power source, connect the receiver, validate the link, and mount the unit.
