Unlike the CPU’s built-in ports, the Serial Communications
Board supports the protocol macro function which can pro-
vide communications between the CQM1H and external seri-
al devices.
The Serial Communications Board has 2 ports: an RS-232C
port and an RS-422A/485 port. The RS-422A/485 port sup-
ports 1:N connections (protocol macro or NT Link in 1:N
mode) without an adapter.
