A CVM1/CV series Host Link Unit (CV500-LK201) has two connectors (com-
munications ports 1 and 2). Either of these ports can be used for connection
to an NT31/NT31C by the RS-232C method. However, since the connectors
at these ports are of different types, a cable that matches the connector must
be prepared.
CPU Bus Unit Settings
When connecting to a CVM1/CV-series Host Link Unit, set the following com-
munications conditions for the CPU Bus Unit settings.
Communications speed
Transfer code
Parity
1-to-1, 1-to-N
Instruction level
• Communications port 1
• Communications port 2
Communications port 1 is a 25-pin connector for RS-232C use only.
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-232C
method, the I/O port selector switch on the front of the Unit must be set to
RS-232C (the upper position).
