What does rOM.E mean?

This error indicates that the remote display terminal has detected an internal Read-Only Memory (ROM) anomaly, typically identified by a checksum calculation failure. This points to a critical internal hardware malfunction within the display terminal's firmware storage. The terminal's basic functionality may be compromised.

Complete Troubleshooting Guide

  1. 1

    The ROM anomaly suggests a permanent internal hardware fault in the remote display terminal.

  2. 2

    Replace the remote display terminal as it is likely unrecoverable.

  3. 3

    Before replacing, try cycling power to the remote terminal, but this is unlikely to resolve a ROM checksum error.
