Omron CQM1H-SCB41
Omron CQM1H-SCB41 Serial Communications Board
One RS-232 port
One RS-422A/485 port
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 computers, 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.
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 protocol macros or 1:N-mode NT Links.
