D-Sub DB-25 Pin Assignments

AES I/O

I/O Mode can be configured in the software to set the physical connectors between 8×8 I/O channels and 4×12 I/O channels.
Please note: AES3 is running digital audio in channel pairs (stereo) on one physical pin.

Analog I/O

I/O Mode can be configured in the software to set the physical connectors between 8×8 I/O channels and 4×12 I/O channels. The outputs on the Analog I/O connectors thus are labeled to be the upper 4 of the total 12 outputs.

Analog Outputs

AES3 I/O Relay Bypass Settings

AES3 I/O Relay Bypass

The AES3 inputs and outputs provide a relay bypass feature that, when enabled, activates in the event of a power failure or upon a deliberate command from the GUI.

In order to enable the relay bypass feature, the jumpers for each AES3 pair (A) must be in place as shown in Figure 1 below. Removing the jumpers prevents relay bypass from occurring.
