Hi Chris,
The USB-RIM is set to use an active high signal for both COS and CTCSS. I have the PL line set in the wildcard however I just noticed that there isnt a output for pin C2 in the output group settings. There is an output for pin C4.
Other thing the wildcard checkbox is greyed out on the system configuration screen.
Thanks

Wildcard programmed in the MTR? I take it you're using a transistor inverter to talk to the USB which normally requires a low going signal?

All,
I have a MTR2000 here that I have interfaced to a USB-RIM module, I
have
it working in COS mode but want to run a ctcss code on it.
I was curious does anyone know if anything special needs to be set for
the ctcss valid pin to go high to tell the RIM that the correct PL/
ctcss
is valid?? I cant get the ctcss lead to go high to tell the RIM that
there's a valid ctcss code.? When I key up my handheld with the correct
ctcss code on it it initially says keyed under the signal status.
Ive tried several mixtures of settings.
Under Audio I have Analog RX Activation set to PL
Under channel info I have decoder set to RX PL of 67.0
I am using the ICS-CTRL MTR2000 Adapter board that goes to a DB9.? Its
pulling from C2 for PL Detect & B4 for COR.
Thanks!
