PS/2 Keyboard and PS/2 Mouse: A PS/2 “Y” cable (provided) is required for this mode.

1 Slide Switch selection:
PS/2 mouse and keyboard

PS/2 Keyboard and USB Mouse: Slide switch to the center position

2 Slide Switch selection:
PS/2 keyboard and USB mouse

USB Keyboard and USB Mouse: Slide switch to the far right position.

3 Slide Switch selection:
USB keyboard and USB mouse

NOTE: When configuring the switch as a Slave in a cascaded configuration, PS/2 Keyboard and Mouse is the only mode that can be used. Therefore, SV431DUSB cannot be configured as a slave in a cascaded setup, as it does not provide a slide switch selector.

NOTE: When using a combination Keyboard and Mouse use the USB Keyboard Port for product revision 1 – 4. For product revision 5 and up use the USB Mouse Port to connect the device.

Computer Installation

USB Computer
To connect a computer controlled through USB, use a StarTech.com 2-in-1 UltraThin USB KVM cable (Product ID: SVECONUS ) to connect from one of the PC Ports located on the rear panel of the KVM switch to the USB and VGA ports on the computer system.

StarTech.com Ultra-Thin KVM Cable

1. VGA port
2. USB port

PS/2 Computer
To connect a computer controlled through PS/2, use a StarTech.com 3-in-1 Ultra-Thin PS/2 KVM cable (Product ID: SVECON ) to connect from one of the PC ports to the PS/2 keyboard and mouse, as well as the VGA port of the computer system.

Cascaded configurations

NOTE: The master must have equal or more PC ports than that of the slave. For example, if an 8-port switch is the Master, an 8-port or 4-port switch can be a Slave, but not a 16-port switch.

NOTE: PS/2-only models can be cascaded with USB+PS/2 universal models.

NOTE: To be used as Slaves in a cascaded configuration, the slide switch on SV831DUSB or SV1631DUSB must be adjusted to PS/2 mode.

The ports labelled PC 1 – PC 8 can be connected to either a computer or a Slave’s CONSOLE port. The ports marked PC A – PC H can only be connected to computers. Use only the 3-in-1 (PS/2) cables to connect the Master’s PC ports and Slave’s CONSOLE port.

1. Master KVM switch
2. Slave KVM switch

The maximum number of computers controlled by a Master/Slave configuration with all 8-port units is 64, with 8 Slaves and each Slave connecting to 8 computers:

The maximum number of computers controlled in a Master/Slave configuration with all 16-port units is 136, with 8 units of 16-port Slaves (to PC 1 – PC 8) and each Slave connected to 16 computers, plus 8 more computers connected directly to the Master (to ports PC A – PC H):

After the connection has been completed, please re-activate the OSD menu to verify that the Master recognizes the Slaves. A triangle mark ( ) is placed next to the right of the channel name indicating that 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 an 8-port switch.

NOTE: A device (computer or KVM switch) 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 port connections from a computer to a Slave KVM switch or vice versa, or replace the devices of a port, the OSD will update this change the next time it is activated.

Operation

You may select a computer by pressing the front panel push button directly, by issuing hot-key commands or by activating the OSD window. The front panel indicator changes to reflect the computer port selected (red) and whether the port is connected to a powered computer (green). The indicator flashes red when it is in either Auto Scan or Manual Scan mode.

Push Button controls

To select control of an attached computer, press the front panel button that corresponds with the assigned computer number. For 16 port models, 1 to 8 represents the lower 8 ports, while A to H indicates the higher ports. Ports 1 and A share the same push button, as do 2 and B, 3 and C etc.

Example: If port 1 is already selected and you wish to switch to Port A, tap the shared push button once to select Port A. If Port 1 is not selected, press and hold push button 1 for two seconds to select Port A.

K/M Reset
K/M Reset resolves the majority of problems developed by keyboard and/or mouse device replacement or configuration changes. Press down buttons 1 and 2 simultaneously for 2 seconds to reconfigure the whole system without having to turn off the KVM switch or any attached computers.

Auto Scan
This KVM switch provides an easy to use feature to start Auto Scanning. To use this function, simultaneously press buttons 7 and 8 and hold for two seconds. (SV431DUSB uses buttons 3 and 4 to launch this function).

Country Code for Sun:
Sun keyboards of different languages have different layouts. The KVM switch is able to emulate a Sun keyboard for a specific language type or country such as Arabic, Belgian, US, Yugoslavia, etc. Select the proper country code that matches all of your Sun computers.

NOTE: The country code must be set prior to powering up the Sun computer. Not performing this step prior to power-up could cause the system to malfunction.

Max. Resolution:
The KVM supports widescreen, and you can adjust the monitor resolution under this submenu. The following selections are available: 1024 x 768, 1280 x 1024, 1600 x 1200, 1920 x 1440 and “DDC2B Disable”.

Function Key :
To switch the Sun mark of a port on or off indicating the computer is a Sun server. Sun servers have more keys on the keyboard than a PC. When a Sun- marked port is selected, the KVM Switch starts to translate the keys from a PC keyboard to a Sun keyboard. See the section entitled Sun Keyboard Mapping for further detail.

NOTE: It is unnecessary to switch the Sun mark ON or OFF if an authentic Sun keyboard is being used on the console. In other words, you must ensure that the Sun-marked port has not been selected if you are already using a Sun keyboard.

With different types of keyboard and computer, the Sun Mark must be set up in compliance with the following instruction:

ESC: To exit the OSD, press the < ESCAPE > key

Hot-key Commands

Hot-key command is a short keyboard sequence used to select a computer, to activate computer scan, etc. The KVM interprets keystrokes followed by one or two more keystrokes. A built-in buzzer generates a high-pitch beep for a correct hotkey command, otherwise, one low-pitch beep for an error and the bad key sequence will not be forwarded to the selected computer.

The short form hotkey menu can be turned on as an OSD function (< F4

:MoreHotkey Menu) every time the left < CTRL > is pressed twice.

NOTE: Left < CTRL >: refers to the Control key on the left side of the keyboard.

1~8/A~H: refers to the number keys ‘1’~’8′ in the upper row of the keyboard and character keys ‘A’ ~ ‘H’. Do not use the keypad at the right of the keyboard.

To select a computer by hotkey command, you must know its port number, which is determined by the KVM Switch connection. For a computer connected to a Slave, two characters represent its port. The first character is the port number of the Master unit (1~8) and the second one is the port number of the Slave (1~8 or A~H). Please note that only the Master’s ‘PC1′ ~ ‘PC8′ ports can be connected to a Slave.

EXAMPLES:
Left < CTRL > , Left < CTRL >, < 7 > : Selects a computer connected to port 7 of the Master.
Left < CTRL > , Left < CTRL >, < 6 >, < C > : Selects a computer connected to port C of a Slave connected to port 6 of the Master.

Auto Scan
In this mode, the KVM Switch automatically switches from one power-on computer to the next, sequentially, in a fixed interval. During AutoScan mode, the OSD displays the name of the selected computer.

Left < CTRL >, Left < CTRL >, < F1 >

When Auto Scan detects any keyboard or mouse activity, it suspends the scanning until the activity stops. It then resumes with the next computer in sequence. The length of the Auto Scan interval (Scan Rate) is adjustable. To abort Auto Scan mode, press the left < CTRL > key twice.

NOTE: Scan Type determines whether an eye-marked computer is to be displayed during Auto Scan.

Manual Scan
This mode enables you to manually switch back and forth between the powered computers:

Left < CTRL >, Left < CTRL >, < F2 >

Press the < UP > arrow key to select the previous computer and the < DOWN > arrow key to select the next computer. Press any other key to abort Manual Scan mode.

NOTE: Scan Type determines whether an eye-marked computer is to be displayed during Auto Scan.

Scan Rate
To adjust Scan Rate, which sets the duration before switching to the next computer in Auto Scan:

Left < CTRL >, Left < CTRL >, < F3 >

The switch will beep one to four times indicating the scan interval of 3, 8, 15 and 30 seconds respectively.

To adjust keyboard typematic rate (characters/sec) for PS/2 keyboards:

Left < CTRL >, Left < CTRL >, < F4 >

The KVM switch beeps 1 to 4 times corresponding to 10, 15, 20 and 30 characters/sec respectively.

Sun/Mac Keyboard Mapping
The KVM Switch emulates a Sun Keyboard when a computer is marked with a Sun, in the OSD menu by Function Key < F5 >. A Sun keyboard has more keys than a standard PC keyboard. These extra keys are simulated by tapping the Right < CTRL > button, which is normally located on the right lower part of the keyboard, followed by one of the function keys on the general keyboard (i.e. combo key). For example, tap the Right < CTRL > key, and then tap the function key < F7 > to activate Open for a Sun computer.

NOTE: For older Sun Operating Systems, the switch does not support the Low Power option under Power Off Select.

For keystroke emulation of Sun/Mac computers, please refer to the above chart and conduct the following two examples:
“Stop A” function in Sun: Press right < CTRL > and release, then within two seconds press < F1 > and < A > in sequence.
“Help” function in Sun: Press right < CTRL > and release, then within 2 seconds, press < H >.

Change Leading Hotkey
The default leading hotkey sequence involves pressing the left < CTRL > twice in succession (e.g. left < CTRL >, left < CTRL >). This can be changed to the right < CTRL > key instead, to avoid accidental activation due to using the left < CTRL > key for functions such as Copy/Paste.

To change the leading hotkey sequence to Right < CTRL >, do the following:

Left < CTRL >, Left < CTRL >, hold < ALT >, press Right < CTRL

All hotkey commands that previously required pressing the Left < CTRL > will be switched to requiring the Right < CTRL > instead.

To change the leading hotkey sequence back to Left < CTRL >, do the following:

Right < CTRL >, Right < CTRL >, hold < ALT >, press Left < CTRL >
