Radiant P1550 serial port pinout RJ12 to DB25M printer

[mcdon]

I am trying to use an Epson T88 serial printer connected to one of the serial ports on a Radinant P1550 terminal but cannot find any information on the pinouts and wiring. Any idea on where to get a manual for this terminal, Radiant does not want to supply any information. A serial port wiring diagram for RJ12 to DB25M would really help.

I don't know your specific Cat5 cable, but try this if you can use the DB9 serial ports on the Radiant instead of the RJ12 serial ports -

DB25 END
Red - Pin 3
Green - Pin 2
Yellow - Pin 7
Brown - Pin 20

DB9 END
Red - Pin 3
Green - Pin 2
Yellow - Pin 5
Brown - Pin 8

Thanks for the quick response, the problem is the P1550 does not have any DB9 connectors, just 8 RJ12 com port jacks.

Thank you for your time and effort, this was the wiring diagram that is no where to be found.
