You need either the CEN-ERFGW or the new CEN-GWEXER gateway for a 6x to communicate to the processor. It will not communicate using the built in gateway on the PMC3.
I know there was a firmware upgrade that did allow a couple gateways to communicate to both types of devices, however I'm not certain that it was/would be pushed to the MC3/PMC3
Last update for the PMC3 allows all Crestron gear to work with it from what I was told. I have upgraded a PMC3 and added Crestron remotes without issue.
On the TPS-6x page it says the only gateway is the CEN-ERFGW-POE. I've never done one but would think Crestron knows what it works with.
