RS-232 interface for A-Series computers.
The most common cable available for these interfaces is the 12005-60004, for connection to a modem. These cables can be modified to use for a direct connection to a terminal. The 12005-60004 cable consists of a standard male DB25 connector at the terminal/modem end and a 48-pin edge connector at the computer end. When looking at the edge connector of the cable with cable pointing down, the pins along the left side are 1 through 24 from top to bottom. The pins along the right side, from top to bottom, are A,B,C,D,E,F,H,J,K,L,M,N,P,R,S,T,U,V,W,X,Y,Z,AA,BB.

The easiest way to modify the standard cable to work with a direct-connect terminal is to swap S and W at the edge connector end (or 2 and 3 at the DB25 end).

Make sure that no other interface card in your system has dip 1 set to C (otherwise you will have a VCP conflict). Configure your terminal to the following settings:
