INSTALLATION

1. Ensure that power is turned o or disconnected from the unit and the computers.

2. Use a DVI cable to connect the DVI output port from each computer to the corresponding DVI-I IN

ports of the unit.

3. Use a USB cable (Type-A to Type-B) to connect a USB port on each computer to the respecve

USB ports of the unit.

4. Oponally connect a stereo audio cable (3.5mm to 3.5mm) to connect the audio output of the com-

puters to the AUDIO IN ports of the unit.

5. Connect a monitor to the DVI-I OUT console port of the unit using a DVI cable.

6. Connect a USB keyboard and mouse in the two USB console ports.

7. Oponally connect stereo speakers to the AUDIO OUT port of the unit.

8. Finally, power on the KVM by connecng a 12VDC power supply to the power connector, and then

turn on all the computers.

Note: You can connect up to 2 computers to the 2 port KVM.

Installation (continued)

EDID LEARN

The KVM is designed to learn the connected monitor’s EDID upon power up. In the event of

connecng a new monitor to the KVM, a power recycle is required.

The KVM will indicate to the user the EDID learn process by ashing the front panel’s LEDs. Port one

green and push buon blue LEDs will both begin to ash for about 10 seconds. When the LEDs stop

ashing, the EDID learn process is done.

If the KVM has more than one video board (such as dual-head and quad-head models), then the unit

will connue to learn the EDIDs of the connected monitors and indicate the progress of the process

by ashing the next port selecon green and push buon blue LEDs respecvely.

The monitor must be connected to the video output connector located in the console space at the

back of the KVM during the EDID learn process.

If the read EDID from the connected monitor is idencal to the current stored EDID in the KVM then

the EDID learn funcon will be skipped.

System operation

front panel control

hotkey and rs232 serial control

There are three ways to control the SM-DVN: Keyboard Hotkeys, RS-232 Serial Commands, and Front

Panel Buons. All modes of control will allow the user the set their desired conguraons.

The SM-DVN may also be controlled via RS-232 commands. To use these commands, you must use

HyperTerminal or an alternate terminal applicaon. The sengs for the connecon are as follows:

Baudrate 115200; Data Bits 8; Parity None; Stop Bits 1; Flow Control None.

Once you have connected to the SM-DVN via Serial, you will see the SM-DVN informaon when the

device starts up.

The following commands can be used for RS-232 with available keyboard hotkeys:

COMMAND DESCRIPTION HOTKEY RS-232 COMMAND

To switch to an input port, simply push the buon on the front-panel of the KVM. If an input port is

selected, the LED of that port will turn on.

Hold down the buon of Front Panel for 3 seconds to force learn EDID.

Led’s behavior

User Console Interface – Display LED:

Front Panel – Port Selecon LED’s:

EDID Learn - Front Panel LED’s:

All LED’s are turned on for 1 second. Then:

• Port 1 LED’s will ash unl the end of the process.

• Port 2 LED’s will ash unl the end of the process if a second video board exists (Dual-head KVM)

IMPORTANT!

If all Front Panel LED’s are on and

not ashing, the POWER UP SELF

TEST has failed and all funcons are

disabled. Check if any of the front

panel port selecon buons are

jammed. In this case, release the

jammed buon and recycle the power.

If power up self test is sll failing,
