To connect the base station, plug the cable into the appropriate port on the rear 
of the IBM 4683/84, 4693/94.

For the IBM 4693, port 9C (which replaces port 17 on the 4683/84) is the 
appropriate port for connecting the base station. Note that port 9C is 
compatible with ports 9A and 9B, which have identical assignments of 
connector pins.

For the IBM 4694, there is one single scanner attachment port, 9E, which is 
equivalent in pin assignments to ports 9A, 9B, and 9C on the IBM 4693.

Note that this variation of port assignments over this range of models 
represents electrical and mechanical changes only. For the IBM 4683/84 and 
4693/94, communications between the attached scanning system and the 
terminal’s operating system device driver programs remain the same.
