HDMI over Cat 5/6 and MSW Power
« on: October 06, 2015, 11:02:24 AM »
I have trouble with the HDMI over cat5 system running on the 1000 watt Xantrex MSW inverter? It works perfectly on Gen or shore power but when I switch to the inverter the TV kicks out intermittently. If I run an HDMI cable directly from my Sat receiver to the TV no problems! I am of the opinion that the HDMI transceiver does not like Mod Sine Wave Power. Anyone else with this problem?

I'm not surprised, the MSW waveform contains a lot of noise in the form of harmonics that can interfere with the low power digital signal on the Cat5 cable.

An update: Kind of an expensive cure but all is well after replacing the 1000W MSW inverter with a 2000W PSW inverter. Also my electric clock no longer gains 20 minutes over night.

^^ That's funny ^^

Our coach was brand new when I replaced the MSW inverter for a Xantrex RS2000 pure sine wave.
