System Requirements
• 1 x StarTech.com 1UCABCONS17 or 1UCABCONS19
• CAB831HD, CAB1631HD: StarTech.com’s 2 in 1 USB KVM cables or 3 in 1 PS/2 KVM
cables
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. Connect your KVM module to your 1UCABCONS17 or 1UCABCONS19 as directed in
their user guides.
3. Attach each of your managed computers to your StarView KVM console’s PC ports
using ultra-thin KVM cables. The CAB831HD and CAB1631HD are capable of using
either 2-in-1 USB or 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 Conguration below.
4. Turn on 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 Conguration
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 congure 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 KVMs can support 136 computers, with 8 16-port Slave KVMs, each
connected to 16 computers. The Slave KVMs 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.

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
Auto Scan
Auto Scan automatically scans through power-on computers at a xed interval:
left Ctrl + left Ctrl + F1
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:
left Ctrl + left Ctrl + F2
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:
left Ctrl + left Ctrl +F3
The CAB1631HD gives o 1 to 4 beeps indicating 10, 15, 20 and 30 characters per
second respectively.
