levelone KVM-3208 KVM Switch User Manual

The KVM Switch now supports longer daisy-chaining distances up to 30M than the previous versions. However, users of previous versions should upgrade all the daisy-chained units to the latest firmware before attempting daisy-chaining.

Active Sync Replication™ for Best Video Compatibility
The KVM Switch features the Active Sync Replication™

(A.S.R.) technology that offers a full-time DDC emulation for best video compatibility with a new type of Operating System that requires all-time DDC communication.

Advanced Autoscan Modes

The advanced auto-scan modes support four scanning modes: either you can scan ALL computer ports regardless of whether they are connected with the computer or not, or you can only those Live computers with power feed, or you can specify whether a computer to be included within the EasyView (EzV) scan group, and scan only within the EzV group. Furthermore, you can scan only those Live computers within the EzV group (Live + EzV). The mode selection can be done on the OSD by accessing Main / Setup / Autoscan mode.
This diverse selection and combination of scan modes will allow users a very flexible autoscanning capability with more subtlety in monitoring a specific set of computers.

Last Known Active Port Restore
This Last Known Active Port Restore, when enabled, will allow the KVM switch to immediately switch to the last known active port when restored to power again after an unexpected power loss. This feature is useful when you need to

track which port is being monitored before a power shutdown or an accidental power loss. By default, this feature is disabled. To toggle on/off the Last Know Active Port feature, just use the hotkey Scroll+ Scroll + L.
Title Bar Positioning Alternatives and Timeout

The title bar which shows the computer name can now be positioned in either left or right position, either with or without a 5-secon timeout option. To select the title bar positioning, just go to the OSD Main Page / Setup / Title Bar, and select it.

INSTALLATION

Take the KVM Switch out of the box and begin installation… If you are using any PS/2 computer: Please make sure all of PS/2 computers be powered off before connecting to the KVM Switch. Otherwise, the KVM Switch system might not be properly set up. However, USB computers do not have this limitation.

Step 1. Make sure (at least the PS/2) computers that are to be connected to the KVM switch are powered off. If not, power them off.
Step 2. Connect the shared keyboard, mouse, and monitor to the console connectors on the rear of your (master) KVM switch. Power on the KVM Switch by attaching the power adapter cord. Although the power is constantly fed through the USB or PS/2 interface from the connected computers, it is still recommended to use the external power adapter for more stability. If you use only a single KVM switch in the non-cascaded application, you should ignore steps 3, ,4 and 5 and jump directly to step 5. If you want to daisy-chain multiple KVM Switches: Go to step 3. You can daisy-chain up to 16 levels of KVM Switches for a total daisy-chain cable length of at least 30M and a maximum total of 256 computers connected. Note that any daisy-chaining attempt to go beyond 30M will suffer a trade-off of video degradation as depending on the cable quality. Daisy-chain user must know: Previous versions of KVM Switch MIGHT NOT be COMPATIBLE for daisy-chaining with the current version. Erratic behaviors might occur if current and older versions work together. If that is the case, you should upgrade all units to the latest firmware version. If still in doubt, please consult your dealer for more information.

Step 3. Use the daisy-chain cable to connect the DaisyChain OUT Port (HDB 15 female) of the master KVM Switch to the DaisyChain IN Port (HDB 15 male) of the second KVM switch. Connect the power adapter cord to the second switch to power it on.
Step 4. If you have yet another switch to be daisy-chained, just repeat Step 3 to connect them. You can daisy-chain up to 16 units of KVM switches. Make sure all the powers of switches are off when adding or removing the KVM switches. Plug a terminator onto the Daisy-chain Out Port of the last KVM switch unit. No Terminator is required if only using a single unit.

Step 5. (Now your KVM switch or daisy-chained KVM Switches should have been powered up and initialized….) Connect each of your computers to a computer port on the rear of the switch (es). You should use the special USB PS/2 KVM cable (with the USB-to-PS/2 adapter) for connection to a USB computer (PS/2 computer

The special KVM cable provides a PS/2 keyboard connector, a USB connector, and an HDB video connector for computer connection. When connecting with a USB computer, just plug the USB connector to it and leave the PS/2 connector free. When connecting with a PS/2 computer, just add one USB-to-PS/2 adapter to the USB connector and you’ll have a PS/2 connector for a mouse. Do not connect both USB connector and PS/2 connector to a computer at the same time

Step 6. Power up the connected computers. After your computer is powered up the keyboard and mouse will be recognized and now you can begin operating the switch

OPERATION

There are three ways to select a specific computer (on a specific switch, if you have multiple daisy-chained KVM switches), using front-panel push button, hotkey sequence or OSD Menu.

Front-panel push buttons

The front-panel buttons let you have direct control over KVM switch operation and port switching. Simply press a button to switch to its corresponding port. See Quick Reference Sheet

Keyboard hotkeys

A keyboard hotkey sequence consists of at least three specific keystrokes: See Quick Reference Sheet

Hotkey sequence = [Scroll]* + [Scroll] * + Command key(s)
User-definable = SCROLL LOCK, CAPS, F12 or NUM LOCK

The two consecutive CapsLK keystrokes should be pressed within 2 seconds and the command key(s) that follow should also be pressed within 2 seconds in a similar manner. Otherwise, the hotkey sequence will not be validated.
For detailed Hotkey sequences and their corresponding functional commands. See Quick Reference Sheet.
OSD Control
To activate the OSD (On Screen Display) Menu, use the hotkey sequence:

Activate OSD = Scroll+ Scroll+ Space Bar
Deactivate OSD = ESC (Escape key)

Main menu

Select computer: use the Up/Down Arrow key to navigate, and PgDn/Up to scroll the page to view computers on different banks. Hit Enter to select.
Edit computer name: just hit Insert to edit and Enter to confirm. F1: Next Page – Rotate through Main Page / Setup page / Status page
F10: Logout – Lock your keyboard and mouse for security. A password will be needed to log in.

F6: EasyView – Toggle select/de-select the highlighted computer to be included with the EasyView (EzV) scan group (by factory default, all computers are). Note that the “V” mark between the bank number and PC name is to indicate that it is included within the EzV scan group.

Status Menu

On this page, the KVM system information of each daisy-chained unit will be shown.
For example:
Mean it’s the first (01) bank of the KVM daisy chain (can be up to a maximum of 16 units), and its firmware version date code is 230324. The model name listed here is , and the port number is eight (16) port.
Firmware Upgrade

This KVM Switch allows its user to upgrade firmware contents whenever is needed to enhance the compatibility to other devices or their functions and performance. For the firmware upgrade procedure, please refer to the Firmware Upgrade Operation Guide.

Technical Support
Please contact your local dealer for technical support issues.

Quick Reference Sheet

Notes:

OSD Menu control is only available when the OSD menu is activated on the screen. To activate the OSD menu, use the hotkey sequenceScroll+Scroll + [Space Bar]. For detailed OSD operation reference, please refer to the User Guide. When the OSD Menu is active, the mouse will be locked until the OSD Menu is off. For detailed OSD function, please refer to previous OSD Menu section.
Note that a, b, y, and z each denote a number key. (ab) = 01 ~ 16; (yz) = 01 ~ 08. For example, Scroll + Scroll + 03 + 06 is for bank 3 port 6. When using a single KVM Switch configuration, thedefault bank no. is 01, therefore hit Scroll + Scroll + 01 + 12 for port 12 for a single KVM Switch configuration.
The password is up to 8-character length. You should remember the password since it is required for access to your KVM switch once you enable the password protection for your KVM switch. However,if you forget the password and thus are blocked from KVM access, you should contact your local dealer for tech support.
