Hi Everyone,
I have an interesting problem that I would like to share and see if anyone knows if this will work. I have two devices communicating with each other via serial interface. It is not really a true RS-232, becasue there is a limited set of signaling. Device 1 transmits unbalanced serial data, Receives balanced serial data, and has one signaling output (a Push-to-Talk to be specific).
Device 2 Transmits Balanced serial data, receives balanced serial data, and uses RTS to handle the PPT input.
Due to the long distance between device 1 and device 2 (>110ft) I would prefer balanced signals throughout. The only signal that would have to have be converted to balanced would be device 1's Tx data. I would like to use an off the shelf 8 channel 232 to 422 converter. and my goal would be to use only one of these with no external bypassing of the device. When I say bypassing, I mean have a signal wire (PTT for instance) go from device 1 to device 2 outside of the inline cable converter.
So my question is: is there a simple way to wire to the converter in which I can pass the three signals (PTT, TX (Bal) A, and TX (bal) B) through this device without any modifications? perhaps put the signal on one balanced pin and ground the other? Something like that?
