Standard Output Connections
NOTE: The two Output 1 outputs, consisting of five BNC connectors and a
15-pinHD connector, output the identical video signal and the same sync format.
The two Output 2 outputs are also identical to each other.
d Video output BNC connectors — Connect RGB video displays to these two sets of
female BNC connectors. Figure 7 shows how to connect the various video formats.

Figure 8. Captive Screw Connector Wiring for Audio Output
ATTENTION:
• Connect the sleeve to ground (Gnd). Connecting the sleeve to a negative (-)
terminal will damage the audio output circuits.
• The length of exposed wires is critical. The ideal length is 0.2 inches (5 mm).
• If the stripped section of wire is longer than 0.2 inches, the exposed wires
may touch, causing a short circuit between them.
• If the stripped section of wire is shorter than 0.2 inches, 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 the applicable portions of the Operation section (see
page 12), Programming Guide section (see page 38), Switcher Software section
(see page 50), and HTML Operation section (page 55).
