Does anyone know how to connect a DSS consol to a Onyx VS KSU? I have tried several configurations but the DSS won't work. The manual says that it is a two port device but doesn't say anywhere how to wire it up!

Thanks, Paul

It has to be the even port. Then it will automatically be assign to station 300.
You can not install a DSS on a expansion cabinet.
Hope this helps

I always install the dss on port 302. you have to leave the next port unwired.I use a red marker on the block.wire the first port normal and program both ports with circuit type 6 if i remember correctly.
