Has anyone used it?
I purchased one last week and played with it over the weekend, Unfortunately Channels 1&2 were somewhat linked where they both needed to be On or neither would play. I readdressed the kepads to 3 & 4 and moved the speaker wires over and all is perfect. I spoke to Monoprice and they sent me an RMA for the unit. (very satisfied with their customer service)
Meanwhile, I loved it so much (both for feature and price) I purchased a second unit since I really need more then 6 zones, and really didnt want to uninstall all the keypads to cross ship a new one.
As a programmer, I also decided to write a RS232 driver for the AMP - if anybody has any interest, or wants to test it's below. I Might open source it after it's tested a bit more.....
Feel free to ask any questions
I wrote a driver, but AVS wont let me post links, but Id be more then happy to email anybody who wants it. It's a Dll and a test EXE, I have also wrapped the DLL with WebAPI and am playing sith some JSON fron ends, and might also make it a Homeseer plugin....
(Update - Now they Posted it)
They are in the manual, but you can get it off the Mclelland or Factor site (same units\spec)
Biggest pain is although a "Bi-Directional" spec, you have to poll it for status updates to raise evens, but the spec isnt complicated.
I'm going to crank up the port speed and see how the device handshakes next and add some better error recovery, then add Tcp\IP sockets and get one of the converters mentioned earlier.
hoping to have this in homeseer or some sort of Java front end
Newer Version of the driver assembly, Test and a new Mixer app for anybody Following\testing my Monoprice Amp app
Additions to the driver include
1) Performance and Stability (dupe command eliminated from pending queue)
2) Ability to pass UI Thread to eliminate Cross thread issues.
3) Preserving Keypad settings so driver can put back after power fail.
Once it stabilizes, will move towards Homeseer
