V83 ECM-1 CABLING
The ECM-1 is installed in the M Series chassis as described in Section 3.5 of the base
unit operator's manual.
NOTE: The ECM-1 cannot be installed as Module 1. If an ECM-1 is removed from
a module slot and a different ECM-1 is installed in that location, the newly installed
module acquires the previous module's configuration. Moving an ECM-1 to a
different module location requires reconfiguration because the configuration
parameters are stored as a function of slot location and module type. The
configuration information does not stay with a relocated module.
The ECM-1 module has a DC-37F connector. The DC-37F connector provides a
means for individual connections to each input/out circuit as shown in Figure 1. Each
input/output has a paired ground (return) connection. If all the input/output circuits
are generated from a common source, a single-point ground can be used. Any of the
ground connections can be used to provide the single-point ground.
