1-1-2 Serial Communications Boards

The Serial Communications Board is an Inner Board for the CQM1H-series PCs.

One Board can be installed in Inner Board slot 1 of a CQM1H-series CPU Unit.

The Board cannot be installed in slot 2.

The Board provides two serial communications ports for connecting host com- puters, Programmable Terminals (PTs), general-purpose external devices, and Programming Devices (excluding Programming Consoles). This makes it pos- sible to easily increase the number of serial communications ports for a CQM1H- series PC.

Port 1: RS-232C

Port 2: RS-422A/485

1-1-3 Features

The Serial Communications Board is an option that can be mounted in the CPU Unit to increase the number of serial ports without using an I/O slot. It supports protocol macros (which are not supported by the ports built into the CPU Units), allowing easy connection to general-purpose devices that have a serial port.
