Fridge Interface Cable:
Connect the 3-Pin Delphi Plug on the Fridge Interface cable to the matching Serial Port on the Controller which
is located just below the control box. Plug the other end into the COM2 Port on the UMD, tighten down and
twist to lock in.
Power Cable Connection:
Once all cables and antenna connectors are in place install the power cable last of all. The Gateway should be
connected to continuous power so that the unit continues to track the asset when the fridge unit is powered
off. With the Supra Series it is convenient to take power from the positive supply side of the fuse F1 and
ground run to fridge chassis.
