6.1 Network Connectors
The NETWORK IN/OUT ports on the front of the GPIO are used to connect the
GPIO with other MCN modules. These ports carry both the network data signals
as well as DC power for power distribution with other modules. Table 7 gives the
pinout for these connectors. Figure 6 shows the location of pin 1 for each port.

6.2 DC IN Connector
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 a subsequent MCN unit. Each power supply can
power one to four units. See Monitoring and Control Network System Manual
S2-60425 for complete details of connections to the network and DC IN
connectors.
