Installation
This section will guide you through the hardware installation of your KVM switch. Please read through this section carefully and complete each step in the order listed.
- Make sure all computers and devices are powered off.
- Plug a PS/2 keyboard, PS/2 mouse, and monitor into the labelled keyboard, mouse, and monitor Console ports on the back of the KVM.
- Attach each of your managed computers to your StarView KVM switch's PC ports using ultra-thin KVM cables. The SV831HD and SV1631HD are capable of using either 2-in-1 USB or 3-in-1 PS/2 cables. The SV1631D1U uses 3-in-1 PS/2 cables. Use the cables to connect one of the PC ports on the back of the switch to the computer's keyboard, mouse, and video ports. Note: These instructions are for a single KVM switch only. For information on cascading multiple KVMs, see Cascade Configuration below.
- Plug the 9V DC power adapter into the power port on the KVM.
- Turn on your computers.
Note: After the initial power up, you can hot-plug additional computers or slave KVM switches without having to power down your KVM.
Cascade Configuration
You can connect a second level of KVMs to one or more of your Master KVM switch's PC ports. The KVM switches connected to the Master switch are known as Slaves. Once connected, the KVM switches will automatically configure themselves as either Masters or Slaves. You can only connect an equal or "smaller" KVM to the Master KVM. For example, a 16-port Master KVM switch can have both 16-port and 8-port slaves. An 8-port Master KVM switch can only have 8-port KVM slaves or lower.
The 8-port KVM can support 64 PCs, with 8 8-port Slave KVMs, each connected to 8 PCs. The 16-port KVM can support 136 computers, with 8 16-port Slave KVMs, each connected to 16 computers. The Slave KVM's must be connected to the 1\~8 ports, not the A\~H ports.
To cascade your KVMs, use a 3-in-1 PS/2 KVM cable to connect one of your Master switch's PC ports to the Slave switch's PC 1\~8 ports. When turning on your cascaded switches, turn on the Master switch before turning on any of the others.
Operating Your KVM Switch
To toggle between computers, you can use the hot-key commands, OSD (On-Screen Display) menu or by using the pushbuttons.
Push Buttons
The LEDs on the KVM switch indicate which computers are turned on (solid green) and which computer is selected (solid red). The indicator flashes red when in Auto or Manual Scan mode. You can press any of the corresponding pushbuttons to select the active computer. On the 16 port models, Port 1 and Port A share the same pushbutton, as do Port 2 and Port B, etc. To select Ports 1 through 8, press the pushbutton once. To select Ports A through H, press and hold the pushbutton for two seconds. Alternatively, if Port 1 is currently selected and you want to select Port A, you can press the pushbutton once to switch to Port A.
The K/M Reset function reconfigures your system without powering down your computers or your KVM switch. To reset the switch, press and hold the front-panel 1 and 2 buttons simultaneously.
The Auto-Scan function automatically scrolls through your connected computers. Press and hold the front-panel 7 and 8 buttons simultaneously to enter Auto Scan mode.

Hot Key Commands
A hot key command is a short keyboard sequence to select a computer, activate a computer scan, etc. A hot-key sequence starts with two Left Control keystrokes followed by one or two more keystrokes. A built-in buzzer generates a high-pitched beep for correct hot-key sequences and a low-pitched beep for errors or bad key combinations that will not be carried out.
The short form hot-key menu can be turned on as an OSD function (
- Left Ctrl refers to the
key located at the left side of the keyboard. - 1\~8/A\~H refer to the number keys 1 to 8 at the upper row of the keyboard (Do not use the keypad at the right of the keyboard) and character keys A to H (case insensitive).
Selecting a Computer
To select a computer by hot-key command you need to know the device's channel address, which is determined by the StarView connection.
- For a computer connected to a Master KVM, the address is represented by the PC port number (1\~8 or A\~H). For example, to access the PC plugged into port 7 of the Master KVM switch, type:
$$ \text { left } C t r l + \text { left } C t r l + 7 $$
- For a computer connected to a Slave KVM, you need to know the channel address of the Slave unit (1\~8) and then the channel address of the device (1\~8 or A\~H). (Please note that only Master's PC 1 to PC 8 ports can be connected to a Slave.) For example, to access the computer plugged into port C of the Slave KVM Switch that is plugged into Port 6 of the Master KVM, type:
$$ \text { left } C t r l + \text { left } C t r l + 6 + C $$
Auto Scan
Auto Scan automatically scans through power-on computers at a fixed interval:
$$ \text { left } C t r l + \text { left } C t r l + F 1 $$
When Auto Scan detects any keyboard or mouse activity, it suspends the scanning until activity stops; it then resumes with the next computer in sequence. The length of the Auto Scan interval (Scan Rate) is adjustable (see Scan Rate on the following page). To abort the Auto Scan mode, press the left Ctrl key twice.
Note: Scan Type (See “OSD Function Keys: F4”) determines whether eye mark is necessary during Auto Scan.
Manual Scan
Manual Scan enables you to manually switch back and forth between power-on computers:
$$ \text { left } C t r l + \text { left } C t r l + F 2 $$
Press the up or down arrow to select the previous or next computer in sequence. Press any other key to abort the Manual Scan.
Note: Scan Type (See “OSD Function Keys: F4”) determines whether eye mark is necessary during Manual Scan.
Scan Rate
Scan Rate sets the duration between switching to the next computer in Auto Scan mode:
$$ \text { left } C t r l + \text { left } C t r l + F 3 $$
The StarView gives off one to four beeps indicating scan interval of 3, 8, 15 and 30 seconds respectively.
Keyboard Typematic Rate
You can adjust the keyboard typematic rate (given in characters/sec). This setting over-rides the keyboard typematic rate of your BIOS and any operating system.
$$ \text { left } C t r l + \text { left } C t r l + F 4 $$
The StarView gives off 1 to 4 beeps indicating 10, 15, 20 and 30 characters/sec respectively.
Audio Stick
An optional multimedia module can be LINKed to the back of each StarView for selecting microphone and stereo speaker signals. There are two options for Audio Stick: On and Off. When set to On, audio selection follows computer selection. When set to Off, audio selection stops following computer selection. It is useful if you want to listen to a particular computer's audio signal while operating other computers.
$$ \text { left } C t r l + \text { left } C t r l + F 5 $$
The StarView gives off 1 or 2 beeps corresponding to On and Off respectively.
Changing Your Configuration
After the initial power up, any device (either a KVM or a PC) can be added or removed from any PC x port on the KVM without having to power down the Master KVM Switch. Make sure that devices are turned off before connecting them to the Master KVM switch.
Note: After changing your configuration, the OSD will automatically update to reflect the new configuration.
