Name
Serial Communications Board
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
possible to easily increase the number of serial communications ports for a
CQM1H-series PC.
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.

Temperature controller
or other device
Both RS-232C and RS-422A/485 ports are provided. The RS-422A/485 port
enables 1:N connections to general-purpose external devices without going
through Converting Link Adapters. The 1:N connections can be used with pro-
tocol macros or 1:N-mode NT Links.
