.
RS-232C Ports
Note
1.
High-speed NT link is only available with Serial Communications Boards/
Units manufactured on or after December 20th, 1999. With earlier models,
only standard NT link is available.
2.
The maximum cable length for RS-232C is 15 m. The RS-232C standard,
however, does not cover baud rates above 19.2 Kbps. Refer to the manual
for the device being connected to confirm support.
Connector Pin Layout
Note
1.
Pin No. 1 and the shell are connected to the ground terminal (GR) of the
Power Supply Unit inside of the Serial Communications Board. Therefore,
the cable shield can be grounded by grounding the GR of the Power Sup-
ply Unit.
2.
The status of the RTS (RS), CTS (CS), DSR (DR), and DTR (ER) signals
can be monitored in the words allocated in the CIO Area. For details, refer
to
2-3 I/O Memory Allocations
.
3.
Pin 6 (5 V) is required when the NT-AL001-E Link Adapter is connected.
For details on connection methods, refer to
Wiring
.
4.
The DSR signal is used to monitor the signal cable. It can also be used as
a CD (carrier detect) signal. (The DSR signal does not affect system oper-
ation, and is available for use by the user.)
