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.
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.

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.

Both RS-232C and RS-422A/485 ports are provided. The RS-422A/485 port en-
ables 1:N connections to general-purpose external devices without going
through Converting Link Adapters. The 1:N connections can be used with proto-
col macros or 1:N-mode NT Links.
