Hi,
I hoping there could be someone who might have experience with this and could offer some advice.
I have a very old piece of equipment (Schaffner NSG 1003) here which I'm hoping to write some LabVIEW drivers for.
I have the old manual for the piece of equipment here and it gives the following pinout for the the remote connector (RS232 25 Pin Female Connector)
Pin Signal
1 Ground
2 RX
3 Tx
4 CTS
5 RTS (Pin 4 and 5 are shorted to each other)
6 DTR
7 Signal Ground
8 Ground
18 +12V
20 DSR (Pin 6,8, and 20 are shorted to each other)
25 -12V
I have tried making a few cables (null modem, straight through etc) but none have yet to work.
I wish to make a cable which uses a DB25 Male connector on the equipment end and a standard DB9 connector on the computer end.
Does anyone have any experience with this pinout and what pins are needed for successful communications?
Also the manual does not state if a termination character is needed.
I assuming one is needed and I'm guessing it is either a LF or CR.
If anyone has any experience with this machine or ideas in general I would really appreciate their input.
Thanks,
Patrick
