The CPM2C’s communication port handles both RS-232Cand peripheral port connections, which are divided internally. Therefore, whenusing the CPM2C, it is necessary to select RS-232C or peripheral port connections, according to the kind of cable and port (on the cable) used, as shown in thefollowing table. Refer to the CPM2C Operation Manual for more details.Peripheral portCPM2C-CN111CPM2CCPM2CCS1W-CN114Peripheral portRS-232C port(D-Sub 9-pin, female)Setting Switches on a C200HX/HG/HE(-Z)E Serial Communications BoardSet the switches on a C200HX/HG/HE(-Z)E Serial Communications Board asfollows.Switch 1:Set to 4 (4-wire, for RS-422A)Switch 2:Set to ON for terminator ON (terminating resistance applied)Setting Switches on a CQM1H Serial Communications BoardSet the switches on a CQM1H Serial Communications Board as follows.Wire selection (WIRE): Set to 4 (4-wire, for RS-422A)Terminator (TERM):Set to ON for termination ON.Serial Communications Board(Inner Board slot 1)Terminator Switch (TERM)Set to ON (right side).Wire Selection Switch (WIRE)Set to 4 (right side).Setting the Switches on an RS-422A AdapterCPM1CIF11CPM1Set the terminator selector switch to ON (upper position).Connecting to a CS-series Serial Communications BoardSerial Communications Board with RS-422A/485 port equipped for CS-seriesCPU Unit Model:CS1W-SCB41 (The port 2 is RS-422A/485 port.)76SectionConnecting to the Host’s RS-422A/485 Port5-1Setting the Front SwitchesRDYCOMM1COMM2Port 1RS-232CPORT1Terminal resistance setting switch (TERM)Set to ON (Terminal resistance is present.)
