Frequently Asked Questions - SM-DVN-44X Smart-AVI

How do I switch between computers on the SM-DVN-44X?

You can switch using the front panel buttons, keyboard hotkeys (e.g., Scroll Lock + Scroll Lock + 1-4), or via RS-232 serial control. Refer to the manual for custom hotkey settings.

Does this KVM support dual monitors?

No, the SM-DVN-44X is a single-monitor DVI KVM switch. For dual monitor setups, consider a model like Smart-AVI's DVI-Dual series.

What video resolutions are supported?

It supports up to 1920x1200 at 60 Hz. It also supports lower standard resolutions such as 1080p and 1680x1050.

Can I use the USB ports for peripherals like a keyboard and mouse?

Yes, the four USB 2.0 ports are for shared peripherals like keyboard, mouse, or USB drives. They emulate dynamically to the selected computer.

Is audio supported through this KVM?

Yes, it has audio input/output jacks (3.5mm) that can be switched along with the video and USB. Use the included audio cables.

How do I reset the KVM if it freezes?

Unplug the power adapter and all USB/audio cables from the switch, wait 30 seconds, then reconnect power first, then cables one by one. This typically resolves most issues.

Can I daisy-chain multiple SM-DVN-44X units?

No, daisy-chaining is not supported. Each unit is standalone for 4 computers. For more computers, consider a larger model.

Does it work with USB 3.0 devices?

The USB ports are USB 2.0 (480 Mbps). USB 3.0 devices will work but at USB 2.0 speeds. For full USB 3.0, look for a KVM with USB 3.0.

What is the maximum cable length for DVI connections?

For reliable signal quality, use DVI cables up to 5 meters (16 feet). Longer cables may cause signal degradation.

How do I update the firmware?

Firmware updates are not typically required for this model. If needed, contact Smart-AVI support for instructions and firmware files.

INSTALLATION

1. Ensure that power is turned off 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-D 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 respective USB ports of the unit.
4. Optionally, connect a stereo audio cable (3.5mm to 3.5mm) to the audio output of each computer to the AUDIO IN ports of the unit.
5. For each user, connect a monitor to each DVI-D OUT console port of the unit using DVI cables.
6. For each user, connect a USB keyboard and mouse to the two USB console ports.
7. Optionally, for each user, connect stereo speakers to the AUDIO OUT ports of the unit.
8. Finally, power on the KVM by connecting a 12VDC power supply to the power connector, and then turn on all the computers.

Note: You can connect up to 8 computers to the 8 port KVM and up to 4 computers to the 4 port KVM.

INSTALLATION (CONTINUED)

EDID Learn:

The KVM is designed to learn the connected monitor's EDID upon power up. In the event of connecting a new monitor to the KVM, a power recycle is required.

The KVM will indicate to the user that the EDID learn process is ongoing by flashing the LED next to DVI OUT port 1. When the LEDs stop flashing, the EDID learn process is done.

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 identical to the current stored EDID in the KVM then the EDID learn function will be skipped unless the force learn EDID process is used. To force learn the EDID, hold down the First and Last CAC buttons of Front Panel for 3 seconds to force Learn

SYSTEM OPERATION

There are three ways to control the SM-DVN: Keyboard Hotkeys, RS-232 Serial Commands, and Front Panel Buttons. All modes of control will allow the user to set their desired configurations.

FRONT PANEL CONTROL

To switch to an input port for a given console, push the UP or DOWN buttons as many times as needed to navigate to the desired channel. The channel number indicator will display to selected channel for each console.

By default, the unit will start in View Mode, indicated by a red LED above the CAC button on the front panel. In View Mode, keyboard and mouse functionality are disabled. Control Mode enables full keyboard and mouse functionality.

HOTKEY AND RS232 SERIAL CONTROL

The SM-DVN may also be controlled via RS-232 commands. To use these commands, you must use HyperTerminal or an alternative terminal application. The settings for the connection 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 information when the device starts up.

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

Command Description	HotKey	RS-232 Command
Switch all USB devices and Main video	[CTRL] [CTRL] c [port #] [ENTER]	//c [user #] [port #] [ENTER]
Switch Channel View Only	[CTRL] [CTRL] v [port #] [ENTER]	//v [user #] [port #] [ENTER]
Learn EDID	[CTRL] [CTRL] e [ENTER]	//e [ENTER]
Trigger Hotplug	[CTRL] [CTRL] h [ENTER]	//h [ENTER]
Reset Software	[CTRL] [CTRL] r [ENTER]	//r [ENTER]
View Current Hotkey	N/A	//hk [ENTER]

CUSTOM HOTKEY TRIGGERS

Users are able to customize the keys that trigger Hotkeys. The default trigger for hot key function on the Keyboard is Ctrl +Ctrl. The trigger function can be used to change to double Ctrl, Shift, or Scroll Lock.

To view hotkey trigger setting:

Type on Keyboard: Alt + Alt + Alt + k + 0 + [Enter]

The LED Light on the user's keyboard will Flash indicating which trigger is currently active

Num Lock LED flash indicates CTRL

Caps Lock LED flash indicates Shift

Scroll Lock LED flash indicates Scroll Lock

To change the hotkey trigger setting:

Hotkey trigger twice + x + [1 | 2 | 3]

1 - Ctrl

2 - Shift

3 - Scroll Lock

Example: If the hotkey trigger is Shift and would like to change to Scroll Lock,

Type: Shift + Shift + x + 3
