MTR2000 PL Decode question


 

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!
