DB25 Connectors
Analog Audio Routers
The analog audio routers use DB25 connectors. Each connector supports 8 inputs (or outputs):
For 16×16 routers, the connectors provide inputs (or outputs) 1–8, 9–16, 17–24, and 25–32,
respectively, and are labelled that way on the rear of the router. Inputs (and outputs) are treated
as 16 stereo pairs.
For 32×32 routers, the connectors provide inputs (or outputs) 1–8, 9–16, 17–24, 25–32, 33–40,
41–48, 49–56, and 57–64, respectively, and are labelled that way on the rear of the router. Inputs
(and outputs) are treated as 32 stereo pairs.
For 32×4 routers, the connectors provide inputs 1–8, 9–16, 17–24, 25–32, 33–40, 41–48, 49–56,
and 57–64, respectively. The inputs and outputs are labelled accordingly. The inputs are treated
as 32 stereo pairs. The single output connector provides outputs 1–8 (4 stereo pairs). The inputs
and outputs are labelled accordingly.
GPIO Connections for CQX Digital Video Routers
The CQX routers use DB25 connectors for GPIO (general-purpose I/O). The connector supports
16 inputs and 4 outputs:
The 16 inputs are in order on pins 1 through 16. The outputs are paired on pins 17–24. Pin 25 is
ground.
