DHV11 Maintenance Card

This document, the EK-DHV11-MC DHV11 Maintenance Card, serves as a comprehensive guide for the installation, troubleshooting, and diagnostic testing of the DHV11 module.

Key information provided includes:

• Troubleshooting Flowchart: A step-by-step guide to diagnose issues, including various configurations and loopback tests (internal, staggered, line).
• Installation Procedure: Basic steps for unpacking, setting up switches, cabling, mounting, and system checkouts.
• Hardware Configuration: Detailed jumper and DIP switch layouts for setting device addresses and vectors, along with an interconnection diagram illustrating how the DHV11 connects to distribution panels and loopback connectors.

• Diagnostic Tools & Usage:

  • Listing of functional verification tests (CVDHA?, CVDHB?, CVDHC?) and their system requirements.
  • Detailed instructions on how to run supervisor diagnostics, including entering commands (e.g., STA/PASS), answering hardware and software parameter questions, and interpreting diagnostic output (e.g., error messages, error-free passes).
  • Examples of diagnostic output for both successful and erroneous runs.

• Technical Reference: Comprehensive tables detailing DHV11 registers (CSR, RBUF, LPR, STAT, LNCTRL, etc.) and their bit-level functions, along with codes for data rates, link types, and diagnostic modes.
