Power Line
The printer provides a +5 volts dc power line to drive the logic of an
external device.
Ground Lines
The printer provides fifteen ground lines consisting of a logic ground,
chassis ground, and thirteen signal return grounds.
Cable/Connector Requirements
The parallel connector must be a 36-pin male plug with a metal backshell
(Amphenol 157-32360 or equivalent). The cable must be shielded with
twisted pair leads (Beldon 9505 or equivalent). The parallel cable must
not exceed 10 feet (3 meters). Figure C-2 shows a typical parallel cable
assembly.
