USB Keyboard and USB Mouse: 3. Both the keyboard and mouse switches must be switched to the right.

USB PS/2 PC 8

Please 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. As such, SV431DUSB cannot be configured as a slave in a cascaded setup, as it does not provide a slide switch selector.

Instruction Manual

Connecting Computers to the Console

USB Only

To connect a computer controlled by USB peripherals, use a 1-to-2 cable (SVECONUSx) to connect from one of the PC Ports located on the rear panel of the KVM switch to the USB and Video ports on the computer, as shown below.

VGA Port USB Port 1-to-2 cable

PS/2 Only

To connect a computer controlled by PS/2 peripherals, use a 1-to-3 cable (SVECONx) to connect from one of the PC ports to the PS/2 keyboard and mouse, as well as the video port of the computer.

Instruction Manual

Cascaded Configurations

Please note: The master KVM Switch must have equal or more PC x ports than that of the slave kvm unit. 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.

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

Please note: To be used as slaves in a cascaded configuration, the slide switch on SV831DUSBA must be adjusted to PS/2 mode.

The ports labelled PC 1 - PC 8 can be connected to either a computer or a slave unit CONSOLE port, as shown below. Use only 1-to-3 (PS/2) cables to connect the master's PC ports and slave CONSOLE port, as shown below.

Master 1-to-3 cable Slave 1-to-3 cable Slave

Instruction Manual

The maximum number of computers controlled by a master/slave configuration with all 8-port units is 64, including 8 slaves and each slave unit connecting to 8 computers as depicted below:

DC9V, 500mA Master Slave Slave Computers Computers

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 pushbutton, 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 pushbutton once to select Port A. If Port 1 is not selected, press and hold pushbutton 1 for two seconds to select Port A.

Hot-key commands

Hot-key commands are short keyboard sequences used to select a computer, to activate computer scan, etc. SV831DUSBA 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 (: More\Hotkey Menu) every time the left key is pressed twice.

(Please Note: Left : designates the Control key on the left side of the keyboard.)

1\~8: designate the number keys '1'\~'8' in the upper row of the keyboard 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).

Left , Left , 7 : Selects a computer connected to port 7 of the master.

Left , Left 6, 3 : Selects a computer connected to port 3 of a slave connected to port 6 of the master.

To start Auto Scan, automatically scan power-on computers individually at a fixed interval:

$$ \text { Left } < \text { CTRL } >, \text { Left } < \text { CTRL } >, \text { F1 } $$

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 key twice.

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

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

$$ \text { Left } < \text { CTRL } >, \text { left } < \text { CTRL } >, \text { F2 } $$

Press “↑”, “↓” to select the previous or the next computer in sequence. Press any other key to abort the Manual Scan.

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

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

$$ \text { Left } < \text { CTRL } >, \text { Left } < \text { CTRL } >, \text { F3 } $$

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):

Left , Left , F4

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

Please note: For older Sun Operating Systems, the switch does not support the LowPower option under Power Off Select.
