------------------------ Introduction Automatic Mouse Conversion

Overview The KVM Switches enable you to connect computers with PS/2 or

serial mouse ports (using adapters supplied with each KVM Switches) and control the computers from one PS/2 mouse(Touch pad). The KVM Switches automatically identifies the mouse and switches to proper mouse protocol.

The SH-6580 is only 1U Four in one control center (KVM switch, KEYBOARD, LCD and MOUSE). It can control up to 8 PCs or 64 PCs by cascade. There is no interface card or software to configure. Installation is as easy as connecting cables between SH-6580 and your computers. Operation is as simple as pressing push button, entering hot-key command and navigating through the user-friendly on-screen menu. Depending on the model yo u have, it switches up to 4 (KVM104D), 8 (KVM108D) IBM-compatible computers. The KVM Switches is independent of the computer operating system.

High Video Quality

KVM Switches supports VGA resolution up to 1600x1200 @85Hz without any degradation (But it is limited by Monitor, so only up to Monitor resolution). Advanced VGA circuit design guarantees smooth and flicker-free switching from one computer to the other with distance up to 100ft (30M)* at both Console and PC sides.

Two-Console KVM Switches (Optional)

The advanced multi-access KVM Switches enable you to control multiple computers from two different locations: one is contained in SH-6580; the other one you can connect from outside, the distance is up to 30M. KVM208D controls 8 computers.

Cascade (Master/Slave) Configuration

You can connect a second level of one or more KVM Switches to “PC 1”~”PC 4” (KVM104) or "PC 1"~”PC 8” ports (KVM108) of a Master unit. Cascade configuration expands system ability allowing you to select computers connected to the Master or Slaves (There is only one Master, which has a mouse, a keyboard and a monitor connected to its CONSOLE port directly operated by a user). Once connected, KVM Switches automatically configure themselves to either Master or Slave. Slaves of different KVM Switches models can be mixed in cascade configuration. [NOT E: Master must have

equal or more PC ports than that of Slaves, i.e., if KVM104 is a master, KVM104 can be Slaves, but KVM108 can not.]

Figure 2: A cascade KVM Switches configuration

Throughout this manual, Master is the SH-6580. Slave is a KVM Switches that has its CONSOLE port connected to a Master's “PC x” port. Slave only exists in cascade configuration.

Multimedia Module

KVM Switch OSD (On-Screen-Display) Operation

KVM104D,KVM108D,KVM116D,KVM208D,KVM216D

An optional multimedia A/V module (MAV108) is used to select microphone, speaker and monitor signals from one out of eight computers. The A/V module is connected to the LINK port on the rear panel via an mini-DIN-8 connector. When a computer is selected, the microphone signal is directed to that computer, speaker and monitor signal source from the same computer.

As an OSD option, the A/V module may select a computer different from that of the KVM Switches system. There are t wo options in Audio Stick function (<F4>:More\Audio Stick). When set to 'On', A/V module selection follows computer selection. When set to 'Off', A/V module selection stops following computer selection. It is useful if you want to listen to one particular computer's audio signal while selecting other computers during operation.

With extra VGA ports, the A/V module enables you to view multiple monitors from one PC at the same time. No w you can extend your Windows desktop for all your computers and switch accordingly.

--------------- Cascade Configuration

Connection

Before connecting a device (a computer or a Slave) to the Master under power, you must turn off the device. The Master must have equal or more 'PC x' ports than that of the Slave, i.e., if KVM104D is the master, KVM104 can be Slaves, but KVM108 can not.

The ports labeled "PC 1"~”PC 8” can be connected to either a computer or a Slave's CONSOLE port, as shown in figure 10. A power adapter with DC 12V output rating must be connected to the Master.

Figure 11: Cascaded 8-port KVM Switches

For OSD model:

After connection completes, you should re-activate the OSD menu to check if the Master recognizes the Slaves. A triangle mark () is placed to the right of the channel name indicating the port is connected to a Slave not a computer. A number to the left of the triangle mark indicates the Slave model, i.e. 8 for KVM108 or KVM108D.

Figure 10: Slave console connection

The maximum number of computers controlled by a master/slave configuration with all KVM104s is 16 with 4 Slaves and each Slave connects to 4 computers, see figure. For an all KVM108s configuration, the number is 64 with 8 Slaves and each Slave connects to 8 computers, see figure 11.

Change Configuration while Running

Devices at any 'PC x' port can be changed at any time after initial power-up. If you change any one of the “PC 1” to “PC 8” ports connection from a computer to a Slave or vice versa, or replace the devices of a port; the OSD will update this change the next time it is activated. [NOTE: Any new device, a computer or a Slave, must be turned off before it is connected to the Master.]

-------------Multi-access KVM Switches

Operation KVM208D

Overview On power up, the KVM208D is in Idle mode broadcasting VGA signal

from the selected computer and detecting for keyboard and mouse activity. User LEDs (marked with reverse black A and B) are both green indicating the KVM Switches is not in use.

The advanced multi-access KVM208D has all the features of KVM108D respectively. The mode l has two Console ports facilitate you to access multiple computers from two different locations, local and remote. Thanks to the high-drive circuit design, you may connect high quality cables at Console and PC sides for up to 100ft (30M), a definite plus for server room applications. No w you can access all computers either in the server room when you have to physically access the computers such as software upgrade, or away from the server room for everyday use.

When keyboard or mouse activity is detected at one CONSOLE, the KVM Switches immediately disables the other CONSOLE from accessing the computer. Only one User LED, at the front panel, remains lit indicating the KVM Switches is under user operation. In the mean time, keyboard LEDs (Num/Caps/Scroll Lock) of the other CONSOLE start to flash as its access is denied and the monitor is blocked from VGA signal for security reason. After the user has finished his operation for a period of time (i.e., User Timeout), the multi-access KVM Switches Switch returns to Idle mode. User

Timeout has four options, 5 sec, 30 sec, 60 sec and HOLD. Select HOLD when you plan to access the KVM Switches for a long time.

Pressing the <Scroll Lock> twice forces the KVM Switches return to Idle mode immediately regardless of the User Timeout setting.

Connections

Connect one keyboards, mouse and monitors to the CONSOLE ports. The built-in PS/2 mouse signal translation enables you to connect PS/2 mice of different type to the CONSOLE ports, i.e., a generic PS/2 mouse for one CONSOLE and a scroll mouse for another.

The User Timeout is available in the OSD menu by pressing the Function key <F4>, under the sub-menu More. Note: Keyboard

Speed option is not available for multi-access models.

Configuration

To expand the number of computers under control, you may connect CONSOLE port of another KVM Switches to "PC 1" ~ "PC 8" port. Refer to the chapter Cascade Configuration for more detail. There are rules to apply for Master/Slave configuration. When KVM208D is a Master, its slave includes KVM104, KVM104D, KVM108 and KVM108D. These multi-access KVM Switches already come with OSD menu, their Slaves do not have to be OSD equipped.
