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, respec-
tively, and are labelled that way on the rear of the router. Inputs (and outputs) are treated as 16 ste-
reo 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 Miranda’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 configu-
ration 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 cre-
ate and maintain lists of all connections.
Your decisions will be based in part on the button layouts of the control panels you have in your
system. Keep in mind that salvos (and salvo buttons) can effect rapid changes that otherwise might
require too much thought or activity from a human operator.
If you have only a few destination devices or just one, you can use a control panels with fewer but-
tons (such as the CP1604, CP1602, or CP3201).
