Omron NT31 NT31C manual PC Setup, When using the peripheral port of CS1G/H

Connecting to the RS-232C Port at the Host Section 4-1

CS1 series CPU type : CS1G/H-CPUjj-E (-V1)

Connect to the built-in RS-232C port of the CPU, or the RS-232C port of the communication board. Note that the connection to a peripheral port must be made via an RS-232C adapter (CS1W-CN118) specially designed for connect- ing to a peripheral port.

PC Setup

When connecting to a CS1 series CPU, set the following communication condi- tions for the PC Setup area. Since the settings shown below are the PC default settings for the CPU, no change to the PC Setup is necessary as long as the communication speed is maintained at 9600 bps.

Item	Setting at Host
Communication speed	Set the same speed as set at the NT31/NT31C(*1)
Stop bits	2 stop bits
Parity	Even
Data length	ASCII 7 bits
Unit No. for the host link	00

*1 Set the host link communications speed at 9600 bps or 19200 bps with the memory switch at the NT31/NT31C. For details, refer to Settings the Host Link Method (page 160). When the communication speed is set to 19200 bps, the PC Setup of the CPU need to be changed.

Either set the PC Setup directly from a Programming Device (Programming Console), or transmit the PC Setup made at a Programming Device (CX-Pro- grammer) to the CPU.

For details on PC Setup, refer to the SYSMAC CS1-series Operation Manual (W339-E1-j).
