2 Plug the Data Cable Atari End into the Atari End on the cable you attach

to the vehicle, i.e., Deutsch adapter or J560 PLC Cable Set.

3 Attach the vehicle interface cable to the vehicle.

— If you’re using the J560 PLC Cable Set, plug into the Power Line

Connector on the outside of the tractor or trailer.

— If you’re using the Deutsch Adapter, plug into the Deutsch Connector

typically located under the dash on the driver’s side, beside the driv-

er’s seat or near the brake ECU on the trailer.

Note:

Not all trailers are equipped with Deutsch Connectors.

4 If you’re using the J560 PLC Cable Set to attach to the

trailer

, connect

the alligator clips to an external power supply; otherwise, turn the trac-

tor’s key to the “on” position.

Selecting a Protocol & Registering the ECU

NEXIQ Brake-Link™

uses the SAE J1587

communication

protocol to interact

with the vehicle’s brake controllers. It sends and receives diagnostic informa-

tion (i.e., J1587 messages) over the:

• J1708 Bus

• Power Line Carrier (PLC) (only available if the ECU(s) support En-

hanced PLC Mode; see pg .30)

If you’re connecting to a tractor, use the Quick Disconnect

(Figure 2.2) to remove the alligator clips from the cable set first.

Since the tractor provides power, the alligator clips are

unnecessary and could potentially cause a short.
