Introduction
Thank you for purchasing a StarTech.com 1U KVM module. Designed for use with
StarTech.com’s CABCONS17 or CABCONS19 integrated cabinet consoles, these

Auto scan modes for easy monitoring of your PCs.

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

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 Conguration 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 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 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.

The port number (or channel address) of the currently selected computer is displayed
in red in the top right of the screen.
The device name is green if the device has power and is ready for selection or white if
it has no power. The OSD menu automatically updates the color when it is activated.
On the 16-port models, use the <Page Up> and <Page Down> keys to view the other

select it.
Press <ESCAPE> to exit the OSD menu and remove the OSD menu from the screen.
A triangle mark on the right side of the screen indicates the port is cascaded to a
Slave KVM; the number at the left of the triangle mark shows the number of ports the
Slave has. With that port highlighted, press <ENTER> to bring up a screen listing the
computers connected to that Slave. The name of the Slave KVM will be shown at the
upper right corner of the OSD menu.
An eye mark on the right side of the screen indicates that the computer has been
selected to be monitored in Scan mode. You can switch this mark on and o using
function key <F2>.
Press <ESCAPE> to exit the OSD and to return to using the selected computer. The
computer name is shown on the screen.
OSD Function Keys

the <UP> and <DOWN> arrow keys to highlight it, then press <F3>. Now, enter up to
4 characters (A to Z, 0 to 9, dash) followed by <ENTER> as new password. A Security-
enabled device is marked with a lock beside its channel number. To permanently
disable the security function from a locked device, highlight it, press <F3> then enter
the password.
If you want to access the locked device temporarily, simply highlight it and
press <ENTER>. Enter the password and you can access the device. The device is
automatically re-locked once you switch to another device. During Scan mode, OSD

Auto Scan
In this mode, the KVM automatically switches from one power-on computer to
the next sequentially in a xed interval. During Auto Scan mode, the OSD displays
the name of the selected computer. 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. To abort Auto Scan mode, press the left <CTRL>
twice, or press any front button. Scan Type and Scan Rate set the scan pattern.
Scan Type (<F4>: More\Scan Type) determines if scanned computers must also
be eye mark selected. Scan Rate (<F4>: More\Scan Rate) sets the display interval
when a computer is selected before selecting the next one.
Manual Scan
Scans through power-on computers using keyboard control. Scan Type (<F4>:
More\Scan Type) determines if scanned computers must also be eye mark
selected. 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 the Manual
Scan Mode.
