I'm new to the RS-232 control world, and I'm having trouble controlling my JVC projector through my RFX9600 controller box and a TSU9400 remote. I connected the projector to the RFX using a home made cable (pins 2,3,5 on the projector side, and Rx, Tx, Gnd on Serial port 4 on the controller box side). Then using the JVC remote Contol Guide, I created a RS device in PEP2 and used Hex code "21 89 01 50 57 31 0A" for power ON, but when I tried it using a test button on the remote, it does not work. I even tried inverting the Tx and Rx cables on the controller box, with the same result. Can anyone help?

Are you able to control the projector from a PC using hyper terminal or a similar program. I have controlled JVC projectors many times via serial and that is the same string I have always used for Power On. I don't really program Pronto's on a regular basis anymore, but make sure in the software you have it designated as HEX before putting in the code. Also make sure you have the properties set up right, 19,200/8/None/1. Oh yea, be sure to use a crossover cable for pins 2 and 3. Hope that helps.

Thanks. I checked the PEP2 software when I inputed the code and it was designated as Hex. Also checked the properties for the device and set them to 19,200/8/None/1, and finally I also tried using both straight and crosover cable for pins 2 and 3. But allways got the same result, No response. One thing I don't know, is if I have to convert the JVC Hex string to something else before using it in PEP2 and the remote?

I'm not sure about PEP2 software, but like I said use Hyper Terminal or a similar program. I prefer Docklight myself, but this way you can just test the codes via your PC and then verify the proper codes before putting it into the pronto software. Hope this helps.
