All CEM's on an ETCLink network contain the configuration for the entire system. Each CEM controls only its own rack, which is defined by the CEM's ETCLink (Rack) address.
Description of Issue
A "Configuration Mismatch" error indicates that one or more CEM's do not contain the same system configuration as the other CEM's. This is typically a problem when a loaner or spare CEM is placed into the system. This can also occur after a rack transfer to one CEM in a multirack system.
In this situation, the correct configuration from a known-good CEM can be downloaded into the CEM with the wrong configuration. Note that multiple CEM's may show the error, which merely means that one CEM on the network is not like the others.
To help determine which CEM has the wrong configuration, find the CEM which will not allow its ETCLink address to be changed to the highest number rack (e.g. 4-Rack system, one CEM will only allow an ETCLink address of 1 or 2--this is the problem CEM). If all CEM's will allow the highest-rack ETCLink address to be set, you must use other methods to find the rogue CEM, such as looking at Rack types, dimmer types, etc.
To download the configuration, go to the Setup-->Rack menu on the CEM with the incorrect configuration.
- In CEM 2.x, go to "Setup Rack Load Config From X", [Enter], "ETCLink Address", [Enter].
- In CEM 3.x, go to "Setup Rack Transfer Local Rack Addr:X", [Enter], "Setup Rack Load Config From: X", [Enter].
You may need to hit reset on all CEM's which show the "Config Mismatch" error.
