I am all out of ports on a CMM Micro on the mountain. Can I add a
switch to one of the ports to get SYNC and then just use an external supply
to power the Canopy modules that are NOT conected to the CMM?
The CMM Micro provides the 1 pps over th power conductors. You would need to isolate the power supply from feeding back into the CMM but still allow the 1 pps through, and block the 1 pps from getting to the external power supply.
