Auto Scan (with Switcher in Mode A)
When the current channel loses video signal for over 0.5 second, the device will automatically jump to the next active input
channel, (meaning an input channel with a live video source).
For example, suppose Auto Scan is active and all four inputs are connected to video sources. While the monitor is displaying
video from input channel 3, disconnect input 3. The Switcher will automatically switch to input channel 4 and show it on the
display.
Pressing the ▽button on the IR remote control or sending the "PRE" command via RS232 command will switch the device to the
previous active input channel.
Pressing the △button on the IR remote control or sending the "NEXT" command via RS232 will switch the device to the next
active input channel.
Imagine you are switching your TV channels and the remote automatically skips those channel numbers with empty source.
Pressing the ◁and ▷button on the IR remote will switch to the exact previous or next consecutive channel number, whether a
video source is present or not.
Now, if we press ▽once, the Switcher will switch the video source from channel 4 to channel 2, skipping channel 3 since it’s
unavailable.
If we press ◁4 times, the Switch will switch the video source to channels 1-4-3 and back to 2. Note that even though channel 3
does not have any input, the switch will still connect the display to that channel when this button is pressed.
Auto Jump
When Auto Jump is enabled, if a new video signal is connected to the Switcher, the Switcher will automatically switch to the port
with that new video signal.

LED Brightness
LED brightness can be set at 4 different levels:
1. Minimum Brightness
2. Normal Brightness
3. Maximum Brightness
4. Auto-Changing Brightness
By default, brightness is factory set at level 3.
Under Auto-Changing brightness, press any switcher button or IR remote control button, change any video input channel, change
any condition on the Switcher at all and the LED brightness will change to maximum brightness for 5 seconds and then return to
minimum brightness.
RS232 Control
When an RS232 cable is connected between the Console port on the Switcher and a PC, the Switcher can be controlled using
RS232 commands. Using a terminal program with the port settings of 9600,8,N,1 (9600 baud, 1 start bit, 8 data bits, 1 stop bit)
commands can be sent to control connections.
When the prompt displays "COMMAND", a connection is made and it is ready to accept commands.
