Active low transmitter question

[LEDave]

Hi Ioannis - Looking back at the thread I've done a pretty miserable job of it so far certainly information wise and I apologise to everyone.

*I think it would be best to have the Data sheet of the that transmitter.* For sure, I'll add a screen shot then a full data sheet if needed.

I intend to use maybe a 12F683 to pull a Transmitter Input pin LOW for a few m/s to make it transmit then hold the Tx pin high to stop false triggering via floating voltages if this is safe to do this without damaging the transmitter or pic. I'll add some code as soon as possible, here's the screenshot:
