Getting Started

Thank you for taking advantage of ETC's loaner program.

Once you've followed the instructions below, pack up your unit in the box the loaner came in. Please send only the items on the repair order; unless instructed otherwise, do not send in any accessories, cables, or peripherals. If you do not have the appropriate packing material, contact ETC Technical Services.

Please ship to:

ETC, Inc
ATTN: RMA# <your RMA number>
3031 N Pleasant View Rd
Middleton, WI 53562

If you run into any issues while following the process outlined below, contact ETC Technical Services.

First-generation CEM processors (also referred to as CEM Classic) require a configuration to function. If you have a multi-rack system, this configuration must match the one stored on all other racks in the system.

Ensure that power to the rack is disconnected before removing any components. Failure to do so can result in damage to your equipment or personal injury.

Check Functionality

There's a good chance that ETC technical services is ahead of the game with a CEM Classic! If we had a configuration on file or were able to get the configuration info, ETC may have loaded it to your loaner already. Plug in the processor (with the power off) before trying any of the steps below. If your system works as expected, no further action is required.

Load from Another Rack

This is the best option if you have a multi-rack system. If you're not sure whether you do or not, simply put in the loaner processor - if it's a multi-rack system, you'll see an error on every processor that says "config mismatch". You may need to generate defaults to get this error to display. Follow the directions in the "fix" section of CEM "Config Mismatch" Error.

Generate Defaults

If you have a system with only one kind of module, you can simply generate defaults. Follow the directions in Generate Defaults Sensor CEM Classic-All Versions. This will also work if you have a mix of D20s and R20s - just select D20 as the module type and then put all R20 circuits in switched mode.

Other Situations

If you have a situation not described above, or you need help following these steps, please contact ETC Technical Services.
