Set each switch with a flat blade screwdriver so thatthe values or symbols in the setting value window agree with the following.CS1W-SCU21SCU21RDYERHSD2RD2RUNERCSD1RD1UNIT0No. 1Set the unit number to 0 through F sothat it will not duplicate the numbersused in other Units.FECCJ1W-SCU41Set the unit number to 0 through F sothat it will not duplicate the numbersused in other Units.Allocation DM Area Settings for CPU UnitSettings are written from the Programming Device (a Programming Console orCX-Programmer) directly into the allocated DM Area (PC Setup) of the CPUUnit.
After the settings are written, they become effective by turning the powerON, restarting the Unit, restarting the communication port, or execution of theSTUP instruction.The following table shows the words allocated in the DM Area and the settings.m = DM30000 + 100 × unit numberAllocated DM wordValueSettings8000Host Link mode, 2 stop bits, even parity, datalength 7 bits0000Baud rate 9,600 bps.0007Baud rate 19,200 bps.m+120000Transmit delay time 0 ms.m+130000No CTS control Unit No.0 for Host LinkPort 1Port 2mm+10m+1m+11m+2m+3Connecting to a CPU UnitCV-series and CVM1/CV-series (-EVj) CPU UnitsCVM1-CPU01-EV2/CVM1-CPU11-EV2/CVM1-CPU21-EV2PC SetupWhen connecting to a CVM1/CV-series CPU Unit, set the following communication conditions for the PC Setup.ItemSetting at HostBaud rateSet the same baud rate as set at the NT21(*1)Stop bits2 stop bitsParityEvenData lengthASCII 7 bitsUnit #00*1 Set the Host Link baud rate at 9,600 bps or 19,200 bps with the memoryswitch at the NT21.

The CPM2C’s communication port handles both RS-232C andperipheral port connections, which are divided internally. Therefore, when usingthe 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 the following table.

Note that the connection to a peripheral port must bemade via an RS-232C Adapter (CS1W-CN118) specially designed for connecting to a peripheral port.PC SetupWhen connecting to a CS/CJ-series CPU Unit, set the following communicationconditions for the PC Setup. Since the settings shown below are the PC defaultsettings for the CPU Unit, no change to the PC Setup is necessary as long as thebaud rate is maintained at 9,600 bps.ItemSetting at HostBaud rateSet the same speed as set at the NT21(*1)Stop bits2 stop bitsParityEvenData lengthASCII 7 bitsUnit No.
