2. MEMOBUS Port
1) Through the MEMOBUS ports, the CPU10 Module communicates using RS-232C com-
munications with other communications devices connected to the MEMOBUS network.
2) The following tables list some of the communications devices that can be connected to
MEMOBUS ports. These devices must have an RS-232C interface. For some devices,
the MEMOBUS port settings must be changed. These settings are changed on the DIP
switch on the front of the Module. Refer to the next section, 4. DIP Switch, for details on
setting the DIP switch.
