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).
CPU Bus Unit Settings
When connecting to a CVM1/CV series host link unit, set the following communications
conditions for the CPU Bus Unit settings.
Communications speed

Command level
Note 1: Set the Host Link communications speed (baud rate) to 9600 bps or 19200 bps with
Set the CPU Bus Unit settings directly from a Programming Device (e.g., CX-Programmer).
For details on the CPU Bus Unit settings, refer to the SYSMAC CVM1/CV-series Host Link
Unit Operation Manual (W205-E1-@).
Item
the Communications Setting menu item in the CX-Designer and the System Menu
for the NS-series PT. For details, refer to 1-4 Settings for Host Link.
2: The 1-to-N setting enables using a BCC (Block Check Character). It is not actually
possible to connect more than one NS-series PT in a single Host Link.
Set the same baud rate as set at the NS-series PT (See note 1.)
