This adapter breaks out the MTR2000 signals to a DSUB-9 connector that is pinned out specifically for the PI-REPEATER controller pinout allowing for a simple 1:1 DB9 cable to connect the equipment. This pinout is the most commonly used for repeater controllers, and will work with most controllers on the market that use a DSUB-9 pinout.

If you are looking to connect the MTR2000 to a Linker-IIa controller, you should use the MTR2000 Linker IIa adapter.
