Instructions for connecting radios, repeaters AllStarLink interfaces including the RTCM, GPS', URI/URI X and like devices.

GPS

Motorola

CDM

CDMs make great nodes. This eBay reseller has very nice cables. Use to connect to URI or RTCM.

CDM Cable from WB9KNX - Cable 83 has only one output to use for either COS or CTCSS. Use another cable if you need both COS and CTCSS.

MTR-2000

Quantar

The Quantar can be tricky to interface as it's extremely programmable and you will need a wireline card for I/O connections. By default the I/O will not work unless the "wildcard" table is programed. This wildcard table is Boolean logic of interrupt states in the radio, is extremely flexible and frustrating to debug. It's a base station in it's own class.

Note you will want to use BEW mode on the RTCM if using the RTCM do squelch.
