Connecting to a CVM1/CV Series Host Link Unit
CVM1/CV series Rack-mounted Type: CV500-LK201
A CVM1/CV series host link unit (CV500-LK201) has two connectors (communications ports
1 and 2). To use the RS-422A type host link method, set communications port 2 to RS-422A.
Communications port 2 is a 9-pin connector which allows selection of the RS-232C or
RS-422A method. When this port is used with the RS-422A method, the I/O port selector
switch on the front of the unit must be set to RS-422A (the lower position).
