John,

It's been a while since I played with pins/cables. Off the top of my head, at a minimum, you need 3 pins:

             DB9         DB25
Send          2           2
Receive       3           3
Ground        5           7

Ground is easy. I may have reversed Send/Receive but the idea is to have them straight-thru. In some cables or on some devices, the Send/Receive had to be crossed as in 2<-->3 and 3<-->2.

Some devices also liked to have the DTR signal. I remember jumping pins 5 and 20 on a DB25 to keep DTR "high".

Make sure the serial connection speed on the printer matches the print server.

Good luck.

François

Subject: [HP3000-L] Pins for 2563A serial to Print Server

I wonder if anyone can help.

I have an old HP2563A printer which has been hooked up to an HP3000 via a DTC in
the past.

I now want to attach it to the network using a print server.

However, the printserver has a 9-pin connection whereas the serial connection on
the printer is a 25-pin.

Can anyone help me with the pinouts for the 9-pin to the 25-pin so I can get this
printer to work on the network?

Thanks,

John Dunlop
