Introduction
Thank you for purchasing a StarTech.com 1U KVM switch. Our universal KVM switches
let you control either 8 (SV831HD) or 16 (SV1631HD) USB or PS/2 computers using only
one PS/2 keyboard, mouse, and monitor. Our slim 16-port PS/2 switch (SV1631D1U)
lets you connect 16 PS/2 computers using only one PS/2 keyboard, mouse, and
monitor. Switching between your PCs is easy thanks to pushbutton or hotkey
commands. These slim KVM switches take up only 1U of space in your cabinet and use
rear cable connections for maximum space eciency. Each KVM can be cascaded to
support 64 (SV831HD) or 136 (SV1631HD, SV1631D1U) computers and support both
Manual and Auto scan modes for easy monitoring of your PCs.

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.
1. Make sure all computers and devices are powered o.
2. 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.
3. 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
Conguration below.
4. Plug the 9V DC power adapter into the power port on the KVM.
5. 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.

Instruction Manual

Cascade Conguration
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 know as Slaves. Once
connected, the KVM switches will automatically congure 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 Console, 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 Console 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 ashes 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 recongures 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 frontpanel 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 (<F4>: More\
Hotkey Menu) every time the left <CTRL> key is pressed twice.
• Left Ctrl refers to the <CTRL> 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 atthe 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:
left Ctrl + left Ctrl + 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:
left Ctrl + left Ctrl + 6 + C

mode:
left Ctrl + left Ctrl + F3
The StarView gives o 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.
left Ctrl + left Ctrl + F4
The StarView gives o 1 to 4 beeps indicating 10, 15, 20 and 30 characters/sec
respectively.

Instruction Manual

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 O. When set to On, audio selection follows computer selection. When
set to O, 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.
left Ctrl + left Ctrl + F5
The StarView gives o 1 or 2 beeps corresponding to On and O respectively.
Changing Your Conguration
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 o before connecting them to the Master KVM
switch.
