Reply to "Weak or NO DCS signal from TIU"

-No DCS signal on any output channel, potentially a bad receiver chip (MAX 4639).
Not true, but possible. Channel that transmit, but can't receive return signals can be the receive chip. G

Thanks GGG for commenting. Can you elaborate?

I have a TIU that will transmit the watch dog signal on all channels when I first turned on TIU power. But when I use the hand held, both tethered & wireless, I don't get any TUI output signal. Also, can't change the TIU number. I changed the MAX 4693 receiver chip which seems to be common to all channels, but that didn't help. Are there any other components that are common to all channels that would prevent an output signal when the hand held is used?

Thanks,

Bob D
