Hi Dee, I've just stumbled upon your lengthy post and I must say, I'm impressed with your ingenuity and stamina with your project. I have a few thoughts and ideas as to maybe pointing you further in the right direction to getting everything working as you would eventually like it too. The controllers you have (I assume that to be two KX138's and a single HSX3208L, with a single keyboard) should indeed operate together, albeit in a non-standard fashion. Could you please post a schematic of what you are presently trying to achieve, together with a close up of the tilt head receiver board (the unit with the orange relays on it) to show at least the manufacturer or the FCC number, unless you know the manufacturer & model number. This will help with the config of the matrix unit... By far the simplest way to get things going would be to have ONLY one device (preferably the HSX unit) controlling the PTZ and the multiplexer, with the keyboard sending commands only to the HSX. I would also strongly suggest that the PT receiver-HSX baud rates are different to the HSX-multiplexer in order to minimise "pass-through" data exchange. In other words, ensure that the PT receiver (orange relays) is set to 4,800 baud (pelco P&D) and the HSX- multiplexers are set to 9,600. Connect the Aux from the HSX (port 12 on your diagram) to the data in on the mux, and connect the keyboard only to port 10 or 11 on the HSX and the keyboard to port 9 on the HSX. Personally I would loop the video through the mux first then into the HSX unit, and the monitor output from the mux feed into any camera input of the HSX in order to give you a multiple quad or split screen from any output you want (even over your I-Phone). Regarding the PT head doing strange things, is there a "brake" input on the PT head? Generally a PT head has a brake as well as a motor, although this is more prevalent in a DC drive, you might want to check as sometimes if the brake is not connected then the head will "shudder" when you try to move it. Also when the drive "went all over by itself" was this is any particular direction or was it random? One further thing, I noticed that the receiver card has eight relays on it, is there a dedicated relay for AUX1 & AUX2? If there is you may want to wire your resistors through one of them to give you a remote speed choice.....just a thought. Post a schematic and a detailed photo of the RX board and I'll put it together in our workshop to find the correct config for you. Kindest Regards Pete
