The cable fits the "Trigger I/O" ports on Benchmark products. It also fits the "12 V Trigger" in and out ports on many other products. 12V trigger signals can be used to link two products together so that one can control the ON/OFF functions on the other. Benchmark "Trigger I/O" ports can be connected to the "Trigger In" or "Trigger Out" ports on most other products.

This cable can be used to link a DAC2 to an AHB2 so that both power on and off in a sequenced fashion. On benchmark products, the trigger function is bi-directional. Either device can start and stop the other. Press the power button on either device or both will start. Press it again and both will shut down.
