About this Manual
The Extron SW4 3G HD-SDI switcher is a four-input, two
parallel output, multi-rate switcher. It allows up to four SDI
or HD-SDI video input sources to be switched to two identical
outputs on female BNC connectors.
The SW4 HD-SDI supports multiple SDI rates, including
270 Mbits per second, 1.485 Gbps, and 2.97 Gbps.
The switcher can be controlled via the front panel buttons, or via
RS-232 communication, using Extron’s Simple Instruction Set
(SIS
™
).
It also features an auto-input switch mode that automatically
switches to the highest numbered input with active sync pulses
present. Executive mode is available to lock out the front panel
as a security measure.
