4.4.2.2 Remote

The remote version of Model 10D1475J Converter uses the smaller two-piece housing which con-

tains two circuit board assemblies, the 686B789U01 CMF PCB assembly and the 686B790U01

Customer Connection PCB assembly. The 686B790U01 PCB interfaces to the remote 50XM1000

Converter via the supplied interconnection cable.
