Command Timeouts

This document outlines the Field Change Order (FCO) RF72-0001, which addresses "Command Timeouts" and various system-level interface problems identified in RF72 modules. These issues are caused by corrupted list pointers and other firmware-related anomalies when installed in VAX 6000, DS 5000, and VAXft systems. The solution involves upgrading the module firmware to revision D01 or higher (PN 23-024EA-00). The document includes detailed instructions for module replacement, calibration procedures, safety warnings regarding electrostatic discharge (ESD), and system parameter recovery steps.
