Remote Services Console Field Service Manual

This document is the Field Service Manual for the Digital Remote Services Console (RSC), identified as EK-KCRSC-FS-002, published by Digital Equipment Corporation in 1986, with a second edition in 1987. It is intended for Digital Field Service personnel to install, test, and operate the RSC option.

Key aspects of the document and the RSC:

1. Purpose of RSC: The RSC is a microprocessor-controlled data path switch, serving as a Digital Field Service "tool" (not for sale) to enable remote services delivery and diagnosis. It allows remote access to a system's console and communication ports via a modem and telephone line.
2. Key Features of RSC:
   • Does not require a dedicated modem or telephone line; it can share existing ones.
   • Provides remote access to the system communications port using Remote Diagnosis Service Protocol (RDSP) for data integrity.
   • Includes a switch-controlled "LOCKOUT" feature to disable all remote access for security, with a removable key.
   • Offers selectable data rates (300 to 9600 b/s) via front panel switches to match connected devices.
   • Designed for easy troubleshooting and temporary bypass by field technicians.
3. Manual Structure:
   • Chapter 1: Installation: Covers site preparation (telephone line, modem, CPU communications port, AC power, cabling, accessibility), step-by-step installation procedures (unpacking, voltage selection, labeling, power-up test, cable connections for generic and VAX/PC38N systems, data rate settings), and post-installation testing with the Customer Support Center (CSC). It also details the procedure for removing the RSC unit.
   • Chapter 2: Operation: Explains how to use the RSC, detailing the functions of its front panel indicators (POWER, FAULT) and the four keyswitch positions:
     • REMOTE: Gives remote station control of the target system (console).
     • LOCKOUT: Disables all remote access for security.
     • USER PORT: Makes RSC transparent, allowing normal local console and comm port operation (no protocol).
     • REMOTE USER: Allows remote station access to the CPU comm port with DDCMP protocol. It also describes data rate switches, console terminal messages, and the "Local Copy" switch for recording remote I/O activity.
   • Chapter 3: Troubleshooting: Outlines procedures for basic testing of the telephone line, modem, and RSC unit. It provides methods for cable testing and temporarily bypassing the RSC unit. The core troubleshooting philosophy for RSC internal faults is unit swapping.

The document also includes release notes for revision 002, certifications the RSC has received, and a list of related Digital documents.
