What’s The Problem?
If you don’t use a CresNet keypad connected to a DMPS 3-300-C or an MC-3 on the wall for roughly 45 days, it will stop functioning.
You know you have this issue when pressing buttons does not trigger the signal name in the program, but if you manually force the button feedback, the LED lights up.
Why Is This Important?
Stability for room users. You shouldn’t have to worry about how long it’s been since you last used your system. Also, rebooting can cause several minutes of downtime which can hurt if it’s unplanned for. Assuming the person who finds the issue knows what to do.
Why Do You Think This Is Happening?
We’ve been encountering this issue dating back to 2012. What’s actually happening is the processor is not receiving signal from the button pad. From what we can tell, the issue happens from lack of use and possibly power outages.
Recommendation on How To Solve:
As of December 2018, Crestron stopped selling these devices and replaced them with Horizon Keypads. However, if you have one of these legacy devices, here are some steps you can take if you’re having this issue:
- Reboot the processor
- Update the Crestron Firmware
Important: You can’t always just go in and update firmware because the program running on your processor may be compiled against older database versions that are no longer compatible with newer firmware. In these instances, your program will need to be compiled against the latest databases and re-uploaded to the processor.
In order to do this, you need the source code, Crestron Software, and a Crestron Certified Programmer do this work to ensure it’s done properly.
