Connecting to a CVM1/CV
Series Host Link Unit
Connecting to the Host’s RS-422A/485 Port
CVM1/CV-series Rack-mounting Unit: CV500-LK201
A CVM1/CV-series Host Link Unit (CV500-LK201) has two connectors (com-
munications 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).
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.
*1
*2
Set the CPU Bus Unit settings directly from a Programming Device (e.g. SYS-
MAC support software).
For details on the CPU Bus Unit settings, refer to the SYSMAC CVM1/CV-
series Host Link Unit Operation Manual (W205-E1-@).
Communications speed
Transfer code
Parity
1-to-1/1-to-N
Instruction level
Set the host link communications speed at 9600 bps or 19200 bps with the
Comm. Speed memory switch at the NT31/NT31C. For details, refer to 6-7-
2 Setting the Host Link Method (page 161).
The 1-to-N setting enables BCC (Block Check Character). It is not actually
possible to connect more than one NT31/NT31C in a single host link.
Item
Set the same speed as for the NT31/NT31C.
