Standard output connections

The two Output 1 outputs, consisting of five BNC connectors and a 15-pin
HD connector, output the identical video signal and the same sync format.
The two Output 2 outputs are also identical to each other.

CAUTION

Connect the sleeve to ground (Gnd). Connecting the sleeve to a
negative (-) terminal will damage the audio output circuits.

CAUTION

The length of exposed wires is critical. The ideal length is 0.2" (5 mm).

If the stripped section of wire is longer than 0.2", the exposed wires
may touch, causing a short circuit between them.

If the stripped section of wire is shorter than 0.2", wires can be easily
pulled out even if tightly fastened by the captive screws.

By default, the audio output follows the video switch. Audio breakaway,
commanded via the front panel, the Ethernet link, or the RS-232 link, allows
you to select from any one of the audio input sources. See chapter 3,
“Operation”, chapter 4, “Programmer’s Guide”, chapter 5, “Switcher
Software”, and chapter 6, “Ethernet Operation” for details.
