RS232 pin connection

[Ozan ONER]

Hi to all,
My question is not related with the Labview, however I will do the rest with
Labview.
I don't have enough info with the serial cables and the internal pin-to-pin
connection of a serial cable.
For example, for a given pin diagram of a connector like the following:
Pin # Signal
1 GND
2 RXD
3 TXD
4 N/A
5 GND
6 DSR
7 RTS
8 CTS
9 N/A

what should be corresponding pins on the PC? In other words, which pins
should be connected
on the device side and the PC side? I want to establish a RS232 serial
connection, however
I don't have the necessary cable.

thanks in advance.

Depends on what yo
u want. Probably a null modem cable

Look at http://www.arcelect.com/rs232.htm

Select the jump to 9-9 null modem and see a wiring diagram

In order to keep things simple, which works for most instruments. Connect
the Pin2 of the device to pin 3 of the Computer Sr Port. Like wise connect
Pin 3 of the deveice to pin 2 of the comp sr port. Connect 5 with 5. Don't
worry about other connections leave them open. In most cases this may work
unless your inst has some specific connection requirements.

Best Wishes
