connections for maximum space efficiency. Each KVM can be cascaded to support 64 (CAB831HD) or

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 off.

2. Connect your KVM module to your 1UCABCONS or 1UCABCONS17 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. The CAB1631D1U 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.

4. 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 know 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
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.

A slave KVM module may be mounted to the rear vertical poles inside a rack cabinet by the rear brackets
with the connectors facing out.

The connectors (keyboard and mouse) at the Local port on the rear of the KVM module are not applicable
when the module is connected to the drawer by the C-36 connector. When its C-36 connector is not
connected to the drawer, the KVM module can act as a rear-mount stand-alone KVM switch. The Local
VGA port can be connected to an external VGA monitor at any time.

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

A solid red indicator reflects the port selected. 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 front­panel 7 and 8 buttons simultaneously to enter Auto Scan mode.

OSD Operations

By hitting the left <CTRL> key twice within two seconds, you may see the 'Hotkey Menu' if it is enabled
(an OSD option). Or, by hitting the left <CTRL> key three times within two seconds, you will see a 'KVM
MENU' screen (below) showing a list of the computers with corresponding channel addresses, names and
status.
