Hi! i need to switch some relays for an antenna switch on the roof and i cannot pass extra cables so i want to send the control signals from my coaxial cable.
I was thinking to use ICs for infrared remote control PT2262-IR (encoder) and PT2272 (decoder) to send the 38KHz signal on the cable.
Do you think it will work?
Here below is the diagram from the datasheets, i need to figure out how to inteface the cable to the ICs once i have removed the IR leds.
On PT2262 i am not sure if i can just remove the ir led and connect the cable there still using the two transistors Vt1-Vt2; same thing on PT2272
