Hi Melanie and Chris

Many thanks for all your input,
Yes your final configs are about right, both of you added points I hadn't thought of,

(The repeater controller is for a small low power unit, the timeout/lockup watchdogs are incorporated in the main radios, so are not required.)

1. InputTrigger goes Low... this causes OutputLine to go Low
2. If the InputTrigger pulses at anytime that InputTrigger is Low < 1 Second then OutputLine is held on by DelayTime
3. If the InputTrigger => 1 Second then DelayTime is Terminated
4. And I want a Blinky for diagnostic.
5. If possible an led to display whether the delay has been triggered, (this would be an added diagnostic function and a help when setting the rx radio up)

It needs to self monitor for InputTrigger pulses for as long as InputTrigger is Low, and self cancel if InputTrigger stops pulsing.

Hope this is makes sense,

Cheers
Dave..
