Hi Guys
have just been experimenting with the multizone function of the Usb Uirt connecting it to my Multizone Hardware FirM.....
With some simple hardware mods to my hardware and new FirMware ...
I can now send an ir signals (from the Usb Uirt) l to any of my FirM,s 8 zones

......and can also connectmultiple emitters in each zone (8) ...
Im using zone 1 of the Usb Uirt as a zone command channel and Zone 2 as the data channel..So the idea is if i need to send ir to Zone 6 of my FirM Hardware i send out an ir signal zone command 6 via zone 1 of the Usb Uirt and then a very short pause and then send out the data ie vol up via Zone 2 of the Usb Uirt......
Im testing this with xPL and the whole process is quite quick...As a test im sending a dvd chan up + chan down signal and xPL-Uirt responds by sending my ha remote menu start and stop signals via zones 3 + 4 respectively....Ity works quite well and may be a solution for those who have multiple pieces of similiar equipment.....This should also work with any other software that supports multi zoning of the Usb Uirt...
More Soon
