Monoprice HDMI switchers.

[sweller]

Hi, Folks.

Looking at the offerings in the file section, I notice there doesn't seem to be any discrete ON/OFF codes for these. Before I go off trying to reinvent a square wheel, is that because these boxes don't accept or can't recognize discrete ON/OF codes?

Specifically, I'm trying to come up with the codes for the 4x1 with audio out.

TIA!

I don't know what the other users have tried, but these boxes use the NEC1 protocol, so testing the unused OBCs looking for discrete codes would not be too hard.

Worth a try and it can't hurt. Thanks!

If your switch is a Monoprice HDX401TA HDMI the following file contains the input 1, 2, 3, and 4 codes.

It appears that the 401TA uses different codes than the other Monoprice switches because the codes that Logitech has for the 401 in the Harmony database doesn’t work for the 4 inputs.

The following file also contains the list of codes for the Snapstream firefly mini that you can eliminate in your search for discrete on and off codes for the switch (both the 401TA and the mini use the same protocol allowing them to be combined in one device upgrade). The only conflict I have found is the mini stop code causes the 401TA to lockup.
