Thank you for purchasing one of the industry’s most feature-rich dual display KVMs, with USB peripheral
sharing and audio technology. You’ll save money and space by eliminating the need for multiple monitors,
keyboards, mice, as well as USB peripheral devices such as printers, scanners, and more. Up to 127
USB devices can be daisy chained from this KVMP switch. Sharing speakers and a microphone also
offers extra value and convenience for the users.
USB and KVM technology together makes cross-platform management easy. A single USB console can
control a PC and a Mac workstation, and share peripherals and audio between the computers.
We hope you’ll enjoy using your Miniview Dual View USB KVMP switch, yet another first-rate connectivity
solution from IOGEAR

Overview
The GCS1742/GCS1744 USB KVM Switch brings dual head video functionality to IOGEAR’s USB KVM
switch technology. Now, two (GCS1742) or four (GCS1744) dual head computers can be accessed and
controlled from a single console that consists of a USB keyboard, USB mouse, and two VGA, SVGA, or
Multisync monitors.
In addition, the GCS1742/1744 incorporates a two port USB hub that allows each of the computers to
share any USB peripherals connected to the hub on a one-computer-at a time basis. Recognizing the
importance of sound, the switches are also audio enabled. A single microphone can provide audio input
to each of the computers, and you can listen to the audio output of each computer on a single set of
speakers (on a one-at-a-time basis).
The GCS1742/GCS1744 independent (asynchronous) switching feature allows independent switching of
the KVM, USB hub, the second display channel, and audio focus. If you wish, you can give one
computer the KVM console focus, another the USB hub focus, while a third has the audio focus.
Setup is fast and easy; simply plug cables into their appropriate ports. There is no software to configure,
no installation routines, and no incompatibility problems.

Before you Begin
1. Make sure that power to all the devices you will be connecting up have been turned off. You must
unplug the power cords of any computers that have the Keyboard Power On function. Otherwise, the
switch will receive power from the computer.
2. Make sure that all devices on the installation are properly grounded.
Installation

14
Cable Connection
1. Plug your Console devices (USB keyboard, USB mouse, VGA monitors, microphone and speakers),
into the switch’s Console Ports.
Note: Only supports two-piece, powered speakers.
2. Use the Port A KVM cable (the one with the USB connector) to connect any available CPU A port to
the first VGA port and the USB port of the computer you are installing.
3. Use the Port B KVM cable (the one with the microphone and speaker connectors) to connect the
CPU B port to the second VGA port and the audio jacks of the computer you are installing.
Note: Be sure that the Port B cable is in the same CPU port as the Port A cable (ex: if connecting to CPU1, then connect one cable to 1A
port and the other to 1B port)
4. Connect your USB peripherals to the USB ports located on the front and rear panels.
5. If you choose to use external power, plug the power adapter cable into the switch’s Power Jack, then
plug the power adapter into an AC power source.
Note:The power adapter (optional) should be DC5V 2.6A with the inside positive and the outside negative:
6. Turn on the power to the computers.

Hot Plugging
The GCS1742/GCS1744 supports USB hot plugging – components can be removed and added back
into the installation by unplugging their cables from the USB hub ports without the need to shut the unit
down.
Powering Off and Restarting
If it becomes necessary to Power Off the KVM unit, before starting it back up you must do the following:
1. Shut down all the computers that are attached to the switch.
2. Unplug power adapter cable from the switch
3. Wait 10 seconds, then plug the switch’s power adapter cable back in.
4. After the switch is up, Power On the computers.
NOTE: If the KVM switch has become unresponsive or shows erratic behavior, it is highly suggested that you unplug all cables from the
KVM (all KVM cables and power cable) and leave the unit disconnected for 30 minutes. After this, plug all the KVM cables back and
power ON the unit.
Operation

17
Port ID Numbering
Each CPU port on the GCS1742/GCS1744 switch is assigned a port number (1 or 2 for GCS1742; 1 to
4 for GCS1744). The port numbers are marked on the rear panel of the switch.
The Port ID of a computer is derived from the CPU port number it is connected to. For example, a
computer connected to CPU port 2 has a Port ID of 2.
The Port ID is used to specify which computer gets the KVM USB peripheral, and audio focus with the
Hotkey port selection method.
Port Switching
There are two ways to access the computers in your KVM setup:
• Manual switching – pressing the push-buttons on the unit’s front panel
• Hotkey switching – entering commands from the keyboard
Operation

18
Manual Switching
1. Press and release a port selection switch to bring the KVM focus to the computer attached to its
corresponding port. The USB and Audio focus does not change; they stay on the port that they’re
already on.
2. Press and hold a port selection switch for more than 2 seconds to bring the KVM, USB, and Audio
focus to the computer attached to its corresponding port
3. Press and hold port selection switches 1 and 2 for more than two seconds to start Auto Scan Mode.
Tip: To stop Auto Scan mode, simply press any of the port selection switches on the KVM.
