SW4 12G HD-SDI Front Panel
AUTO SWITCH LED — This LED lights when auto-input switching is enabled (see
Auto-Input Switching
on page 7 for more information).
CONFIG port — Connect a USB cable (USB A to mini-B) between your computer
and this female USB mini-B port to configure and control the switcher via PCS or SIS
commands, and to update the firmware.
Input selection buttons and LEDs — Press one of these buttons to select an input
to switch to the outputs. The green LED at the right of each button lights when the
corresponding input is selected. If auto-input switching is in effect, these buttons are
disabled, but the LEDs continue to light to indicate the selected input.
Rate indicator LEDs — These six LEDs light to indicate the incoming SDI rate:
270 Mbps, 1.485 Gbps, 2.97 Gbps, 5.94 Gbps, 11.88 Gbps, or other. If the switcher
detects a rate other than those represented by the other five LEDs, the Other LED
lights.
When the switcher detects a valid rate on the input, the signal is equalized and
reclocked to that rate on the output. If the rate is not a valid one, the input is equalized,
but is not reclocked.
