Connecting computers and printers

The unit provides two serial interfaces for bidirectional data
communication:
X31: 9-pin RS-232-C/V.24 D-sub interface
X32: USB interface (UART)
You can use only one serial interface for data
transfer at a time.
Software updates can only be transferred to the
unit via the USB interface X32.
Connecting computers or printers via the RS-232-C/V.24
interface
A computer or a printer with a serial RS-232-C/V.24 data
interface can be connected to connection X31.
Use a serial cable (see "Accessories", page 19) to
connect the COM port of the computer or printer to
connection X31. For information on the location of the
connections, see "Rear panel", page 20.
Make sure the cable is securely attached. Do not
overtighten the connector screws.
RS-232-C/V.24: Pin layout X31
The wiring of the connecting cable depends
on the device being connected (see technical
documentation for external device).
Pin layout:
With handshake: See Figure 1 in "I" in the Appendix.
Without handshake: See Figure 2 in "I" in the Appendix.
For signal level, see "Specifications", page 24.
Connecting a computer via USB
A computer can be connected to connection X32 via the
USB interface.
Connect the USB port of the computer to connection
X32 using a USB cable (see "Accessories", page 19). For
information on the location of the connections, see "Rear
panel", page 20.
USB Type B (UART): Pin layout X32
For pin layout, see "J" in the Appendix.

4.6 Only ND 287: Wiring of switching inputs
and outputs
The wiring of the switching inputs and outputs depends
on the customer's peripherals (see manufacturer's
documentation).
Personnel requirement
Depending on the peripherals to be connected,
the connection work may need to be carried out
by an electrical specialist.
Example: SELV exceeded.
Connection X41
