MMU2 Program Card Memory Chip Service Bulletin

Product

All MMU2 SmartMonitors

Scope

This bulletin applies to all MMU2 SmartMonitor programmed with firmware versions prior to xx.75 and older. PCB G,H,J.

Issue

We are using a new memory chip on the program card. For all existing monitors we need to update the existing version of firmware so the memory chip will work with the older monitors. All previous cards will work with this version making them backwards compatible.

Identification

When the MMU2 SmartMonitor is powered on, to find the firmware version number go to “Menu”, “Set/View Config” and “Firmware Version”. Any version prior to r7.4 need to be updated so that the monitors can read the new program card.

Root Cause

The memory chip was not available, so we are using a new memory chip for the monitor. The new firmware will be able to communicate with both the new memory chip and the old one.

Operational

When the program card memory is activated on the monitor, if the monitor displays “DIAG:pgmcrd mem gone” this indicates that there is a mismatch on the memory card and the monitor software version.

Corrective Action

Install the updated version of firmware to the monitor. A factory firmware update is required for failed units.
