Customers who want to operate the router through an automation system may contact Grass
Valley technical support for information.
DB25 Connectors
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.
You can use Grass Valley’s WC0053 breakout cable with DB25 connectors.
RJ-45 Connectors
All machine control ports are serial, RS-422, operating at up to 1 MB/s. The interface is RJ-45.
Each port has the following pinout:
A port can be configured as “controlling” or “controlled” or variants (dynamic, master, slave).
That is, the definition of the port can be reversed (Tx becomes Rx and vice versa) either during
configuration or during operation.
Making Connections
When making connections, you will (1) decide which router inputs and outputs to use for each
of your devices and (2) need to remember what you decided. It is strongly recommended that
you create and maintain lists of all connections.
