SW4 3G HD-SDI switcher front panel

A

Auto Switch Active LED — When lit, this green LED indicates

that the switcher is in auto-input switch mode. In this mode, the

switcher automatically switches to the highest numbered input

with active sync pulses. When this LED is unlit, the switcher is

in normal (manual) mode.

B

Mode button — The Mode button is used with the Normal

button (C) or Auto button (D) to select the switching mode.

Mode is a secondary function of the Input 1 button. See

“Selecting Auto-input Switch Mode,” on the next page.

C

Normal button — The Normal button is used with the Mode

button (B) to select normal mode. Normal is a secondary

function of the Input 2 button.

D

Auto[switch] button — The Auto button is used with the Mode

button (B) to select the auto-input switch mode. Auto is a

secondary function of the Input 3 button.

E

Input buttons 1 through 4 — These buttons select inputs 1

through 4. They are also used to access auto-input switch and

executive modes, and to reset the unit to factory defaults.

	The Input 1 (B), Input 2 (C), and Input 3 (D) buttons are also
	used to toggle auto-input switch mode on and off (see “Selecting
	Auto-input Switch Mode,” on the next page).
F	Rate indicator LEDs — These four LEDs light to indicate the
	incoming SDI rate: Not Recognized (a rate other than those
	represented by the other three LEDs), 2.97 Gbps, 1.485 Gbps, or
	270 Mbps (Mbits per second).
	When the switcher detects a valid rate on the input, the signal is
	equalized and re-clocked to that rate on the output. If the rate is
	not a valid one, the input is equalized, but is not re-clocked.
