The DC IN port provides the primary power connection to the module. Power is
distributed through the NETWORK OUT connector to provide power to the
NETWORK IN connector of the MCN unit it is connected to. Each power
supply can power up to four units total. See reference 1 for complete details of
connections to the network and DC IN connectors.
Connector J1 provides the discrete I/O for the user interface signals. Table 5 gives
the pinout for this connector. Figure 9 describes the functions of the I/O signals.
