It took a long time to figure out how to mount the IR receiver, support the ethernet cable & do it without farsteners.  The IR receiver has to be completely in front.  With the new IR sensor mounting, it was finally possible to hold down a preset while clicking through the desk selector to blast all of them.

This design was a failure.

Double sided tape is terrible, but the best way to mount them.  Only 3M brand works.

Along with this process, the rest of the receivers got upgraded to the latest firmware.  Now that they're hot glued, any future programming will require soldering a flexible programming header.

After using this for a while, a hard mounted button panel for each desk would be a whole lot easier, but not if it has tact buttons.  They would all need MHPS2283V buttons, which aren't going to happen.
