Connecting the NT620S/620C to a CVM1/CV Series Host Link Unit
Two types of connectors are provided to CV500-LK201 host link unit. Both of
these connector types can connect to the NT620S/620C with an RS-232C con-
nector cable. Select the connector cable which matches the connector type.
S
To connect to communication port 1
This is a 25-pin RS-232C connector. Use a connector cable with a 25-pin con-
nector on one end and a 9-pin connector on the other end (NT620S/620C
side).
S
To connect to communication port 2
This is a 9-pin RS-232C/RS-422 connector. Use a connector cable with a 9-pin
connector on both ends.
Set the I/O port selector switch to the RS-232C side (upper side) to use this
port.
Connecting the NT620S/620C to a C Series CQM1 Unit
CQM1 can connect to the NT620S/620C by the RS-232C method. Use an
RS-232C 9-pin type connector cable.
S
To connect to the RS-232C port
This is a 9-pin RS-232C connector. Use a connector cable with a 9-pin connec-
tor on both ends.
Connecting to C Series C200HX/HG/HE
When using C series C200HX/HG/HE models, the NT620S/NT620C can be con-
nected to the standard port of the CPU unit, or to ports A and B of the expansion
communication board.
Procure an RS-232C 9-pin type connection cable for the connection. For details
on the specifications, installation method, etc., of the communication board used
for the connection, refer to the “SYSMAC C200HX/HG/HE Installation Guide”
(W302-E1-
