Connecting to a CVM1/CV-series Host Link Unit
CVM1/CV-series Rack-mounted Unit: CV500-LK201
A CVM1/CV-series Host Link Unit (CV500-LK201) has two connectors (com-
munication ports 1 and 2). Either of these ports can be used for connection to
an NT11 by the RS-232C method. However, since the connectors at these
ports are of different types, a cable that matches the connector must be pre-
pared.
• Communication port 1
Communication port 1 is a 25-pin connector for RS-232C use only.
• Communication port 2
Communication port 2 is a 9-pin connector that allows selection of the
RS-232C or RS-422A method. When this port is used with the RS-232C
method, the I/O port selector switch on the front of the Unit must be set to
RS-232C (the upper position).
