Rk8-E Control Cable Module

This document serves as the technical documentation and schematics for the Rk8-E Control Cable Module manufactured by Digital Equipment Corporation.

The first page provides the mechanical assembly layout, identifying components such as connectors (J1 and J2), transistors (Q1), diodes (D1), and resistors (R1). It also includes a parts list detailing component specifications, such as a 0.01µF capacitor, a 470-ohm resistor, and a 1N748A Zener diode.

The second page provides the electrical schematic, detailing the pin assignments and wiring connections between the two main connectors (Connector A and Connector B). It notes that unused pins are grounded, with the exception of specific pins reserved for voltage and signals (BA2 is +5V).
