Operation

Please note: SV431DVIUA can be used with a VGA connection to controlled (slave)

computers, however an adapter must be used to make the connection (please see

Accessory Products from StarTech.com - DVIVGAMF).

Also note: Analog and digital connections cannot be used concurrently. To

successfully connect SV431DVIUA to the slave computers, all connections must be

either digital or analog.

1. Online/Selected LEDs

When the LED turns green, the computer connected to the corresponding port is

powered-on. When a computer is selected, its corresponding red LED illuminates.

2. Pushbuttons

Each computer has a button associated with it on the front panel for selection. For

example, to switch to computer 2, press the 2 button.

Auto Scan

Auto Scan automatically scans through computers one at a time, in a xed interval.

Please note: keyboard and mouse are not operable during Auto Scan. To activate

Auto Scan, press down front panel push buttons 3 and 4 simultaneously. The port LED

ashes during Auto Scan. Auto Scan is eective for powered-on computers only. To exit

the Auto Scan mode, just tap any one of the front panel pushbuttons.

Scan Time

This selection sets the scan interval for the Auto Scan feature. The Scan Time options

are 3, 8, 15 and 30 seconds. Please note: Scan Time is automatically set to a default of 3

seconds, in the event that SV431DVIUA loses power. To change the Scan Time interval,

press both front panel buttons 1 and 2 simultaneously. SV431DVIUA will beep 1, 2, 3 or

4 times for scan time of 3, 8, 15 or 30 seconds respectively.

Instruction Manual

“FUNC” Button

To adjust the optimal video signal strength corresponding to the length or quality of

DVI cable being used, use the FUNC button in combination with the other front

panel pushbuttons.

1. Press the FUNC button three times. The POWER LED will ash once per second.

2. To adjust equalization of the selected port input video strength, press button 1 once

or twice; SV431DVIUA will beep once (normal) or twice (enhanced) respectively.

To adjust the output current of a selected port, press button 3 once or twice ;

SV431DVIUA will beep once (normal) or twice (enhanced) respectively.

To adjust the output emphasis of the selected port, press button 4 once, twice,

three or four times; SV431DVIUA will beep once (no pre-emphasis), twice (low

preemphasis), three times (medium pre-emphasis), or four times (high pre-

emphasis), respectively.

3. Once you have entered the desired settings, press the FUNC button once to save

and exit function settings.

To select the audio signal from any port of 4 connected computers, press the FUNC

button in combination with the other pushbuttons.

1. Press and hold the FUNC button.

If all four green LEDs illuminate: The audio port and the selected COM port are the

same - this is referred to as “tracking mode”.

If just one green LED illuminates (indicating the selected audio port): The audio port

is dierent from the selected computer port - this is referred to as

“non-tracking mode”.

2. While still pressing the FUNC button:

Press the button that corresponds numerically with the desired audio port. e.g if

you wish to select the signal from port 3, press the 3 button while still holding the

“FUNC” button.

Press buttons 1 and 2 to enter tracking mode.
