Overview  
IOGEAR’s new eight-port Miniview® Ultra+ KVM switch is the ideal tool to help reduce redundant hardware.  
Eight monitors, mice and keyboards are simply too expensive, bulky and inconvenient for most system  
administrators. Why bother when you can control all eight, or even up to 512 computers with a single  
keyboard, monitor and mouse? The added audio support allows you to enjoy music while working. Just think  
of the time, space and money you’ll save, and added fun.  
The New Miniview® Ultra+ is much more than a simple eight-port KVM switch. The dual interface support  
allows you to connect both PS/2 and USB computers on the same switch. The multi-platform support allows  
you to control Windows-based computers, Sun Solaris systems, Linux, or even Macs by a single KVM  
switch. IOGEAR extended the multi-platform support by supporting the special keys on both Sun and Mac  
keyboards. This KVM switch also comes with the IOGEAR VSE technology, which provides excellent video  
resolution - up to 2048 x 1536. Built-in AutoScan mode lets you conveniently monitor every attached  
computer for a specified amount of time, while our On Screen Display (OSD) technology allows you to assign  
a unique name to each computer and access it via a smooth menu-driven interface. With its 1U, 19” rack-  
mountable casing and status-monitoring LEDs, the Miniview® Ultra+ is the perfect switch for your server  
room or any other multi-computer environment.

Hot Plugging Console Ports:  
Hot Plugging  
The Miniview® Ultra+ supports hot plugging.  
Components can be removed and added back into  
the installation by unplugging and replugging their  
cables from their respective ports without the need  
to shut the switch down. For hot plugging to work  
properly, the following procedures must be  
observed:  
The unit supports hot plugging of the keyboard,  
monitor, and mouse.  
Note: If there is no response to mouse and/or PS/2  
keyboard input after hot plugging (or at any other  
time), simultaneously press and hold Port Select  
buttons 1 and 2 on the First Stage unit for 3  
seconds to perform a PS/2 Keyboard and PS/2  
Mouse reset.  
Hot Plugging CPU Ports:  
When hot plugging cables from the CPU ports:  
1. The cable must be plugged back into the same  
port it was removed from.  
2. After plugging the cable back in, you must  
perform a KVM Reset on the First Stage unit (by  
pressing the Reset switch In).

Operation  
Port ID Numbering:  
Powering Off:  
Each CPU Port on a GCS1758 installation is  
assigned a unique Port ID.You can directly access  
any computer on any level of the installation by  
specifying the Port ID of the CPU port that the  
computer is connected to - either with the Hotkey  
port selection method (see p. 20), or with the OSD  
(see p. 27).  
If it becomes necessary to power off one of the  
GCS1758 units, you must do the following:  
Shut down all the computers that are attached to the  
unit which do not support hot plugging feature, such  
as PS/2 computers or computers with Novell OS, etc.  
The Port ID is a one, two, or three digit number. It is  
determined by the Stage Level and CPU Port number  
of the switch that a computer is connected to.  
The first digit represents the CPU Port number of the  
First Stage unit; the second digit represents the CPU  
Port number of the Second Stage  
unit; the third digit represents the CPU Port number  
of the Third Stage unit.  
16  
 
Operation  
´ A computer attached to a First Stage unit has a  
one digit Port ID (from 1-4 for the CS-1754; from 1-  
8 for the CS-1758), that corresponds to the CPU  
Port number that it is connected to.  
Second Stage unit, which, in turn, links back to CPU  
Port 2 of the First Stage unit.  
Port Selection:  
´ A computer attached to a Second Stage unit has a  
two digit Port ID. The first digit represents the CPU  
Port number on the First Stage unit that the  
Second Stage unit links back to; the second digit  
represents the CPU Port number on the Second  
Stage unit that the computer is connected to. For  
example, a Port ID of 2 3 would refer to a computer  
that is connected to CPU Port 3 of a Second Stage  
unit that links back to CPU Port 2 of the First  
Stage unit.  
The Miniview Ultra+ provides three methods to  
obtain instant access to any computer in your  
installation: Manual, Hotkey, and OSD.  
• Manual - Simply press the appropriate Port  
Selection Switch on the GCS1758’s front panel.  
After you press the switch, the Selected LED  
lights to indicate that the port has the KVM  
focus. The OSD (see p. 27) automatically  
switches to highlight the computer that you  
have selected.  
´ Likewise, a computer attached to a Third Stage  
unit has a three digit Port ID. As in the previous  
example, a Port ID of 2 4 1 would refer to a  
computer that is connected to CPU Port 1 of a  
Third Stage unit, that links back to CPU Port 4 of a

on the installation. OSD operation is discussed in  
detail beginning on p.27.  
2. Simultaneously pressing Port Selection buttons 7  
and 8 on the First Stage unit initiates the Auto  
Scan feature (see F7 SCAN, p. 20), in which all  
the ports currently selected for Quick View  
scanning (see Set Quick View Ports, p. 30), are  
cycled through. The length of time spent on each  
port is determined with the Scan Duration setting  
under the OSD’s F3 SET function (see p. 31).  
• Manual - Simply press the appropriate Port  
Selection Switch on the GCS1758’s front panel.  
After you press the switch, the Selected LED lights  
to indicate that the port has the KVM focus. The  
OSD (see p. 27) automatically switches to highlight  
the computer that you have selected.  
• Hotkeys - allow you to conveniently provide KVM  
focus to a particular computer from the keyboard,  
instead of having to manually select them by  
pressing Port Selection switches. Hotkey operation  
is discussed in detail beginning on p. 19.  
• OSD - OSD (On Screen Display), provides a menu  
driven interface to handle the computer switching

Operation  
Hot Key Mode (HKM):  
2. There is an alternative key combination to  
invoke HKM. See p. 22 for details.  
The GCS1758 provides an extensive, easy-to-use,  
hotkey function that makes it convenient to control  
and configure your KVM installation from the  
keyboard. All hotkey operations begin by invoking  
Hotkey Mode.  
When HKM is active, the Caps Lock, and Scroll  
Lock LEDs flash in succession to indicate  
that HKM is in effect. They stop flashing and revert  
to normal status when you exit HKM. A Command  
Line appears on the monitor screen. The command  
line prompt is the word Hotkey: in yellow text on a  
blue background. Ordinary keyboard and mouse  
functions are suspended - only Hotkey compliant  
keystrokes and mouse clicks (described in the  
sections that follow), can be input.  
To invoke HKM, do the following:  
1. Press and hold down the Num Lock key  
2. Press and release the Minus key  
3. Release the Num Lock key  
[Num Lock] + [-]  
At the conclusion of some hotkey operations, you  
automatically exit hotkey mode. With some  
operations, you must exit manually. To exit Hot Key  
Mode manually, press the Esc key, or the  
Spacebar.  
Note: 1. The minus key must be released within one  
half second, otherwise Hotkey invocation is  
canceled.

Hotkey Port Control  
Hotkey Port Access:  
3. Press [Enter]. The KVM focus switches to the  
computer associated with the specified Port ID,  
and you automatically exit Hotkey Mode.  
Hotkey Port Access allows you to select which  
computer has the KVM focus. The Miniview® Ultra+  
provides the following Hotkey Port Access features:  
Selecting the Active Port and Auto Scan Mode.  
Auto Scan Mode:  
The GCS1758’s Auto Scan feature automatically  
switches among all the active CPU Ports that are  
accessible to the currently logged on User at regular  
intervals (see Scan Mode of the OSD F3 SET  
function, p. 31), so that he can monitor their activity  
automatically.  
Selecting the Active Port:  
You can bring the KVM focus to any computer with a  
hotkey combination that specifies its Port ID (see p.  
16 for Port ID Numbering details):  
To start Auto Scanning, key in the following Hotkey  
combination:  
1. Invoke Hot Key Mode (HKM) (see p. 19).  
2. Key in the computer’s Port ID number.  
1. Invoke HKM (see p. 19)  
The Port ID numbers display on the Command Line  
as you key them in. If you make a mistake, use  
[Backspace] to erase the wrong number.  
2. Key in [A]. After you press A, you automatically  
exit Hotkey Mode, and enter Auto Scan Mode.  
To exit Auto Scan Mode, press [Esc] or [Spacebar].

Hotkey Port Control  
Alternate Hotkey Invocation Keys:  
Note: While Auto Scan Mode is in effect,  
ordinary keyboard and mouse functions are  
suspended - only Auto Scan Mode compliant  
keystrokes and mouse clicks can be input. You  
must exit Auto Scan Mode in order to regain  
normal control of the console.  
An alternate set of Hotkey Invocation keys is  
provided in case the default set conflicts with  
programs running on the computers.  
To switch to the alternate Hotkey Invocation set, do  
the following:  
While you are in Auto Scan Mode, you can pause  
the scanning in order to keep the focus on a  
particular computer by pressing P. During the time  
that Auto Scanning is paused, the Command Line  
displays: Auto Scan: Paused. Pausing when you  
want to keep the focus on a particular computer is  
more convenient than Exiting Auto Scan Mode  
because when you Resume scanning, you start  
from where you left off. If, on the other hand, you  
Exited and restarted, Scanning would start over  
from the very first computer on the installation.  
After pausing, to resume Auto Scanning, press any  
key. Scanning continues from where it left off.  
1. Invoke HKM (see p. 19)  
2. Press and release the H key. The Hotkey  
Invocation keys become the Ctrl key (instead of  
Num Lock) and the F12 key (instead of Minus).  
Note: This procedure is a toggle between the two  
methods. To revert back to the original [Num Lock]  
[Minus] method, invoke HKM, then press and  
release the H key again.

screen. The OSD Hotkey will bring up the Main  
OSD Screen.

Firmware Upgrade Utility  
The Windows-based Firmware Upgrade Utility  
(FWUpgrade.exe) provides a smooth, automated  
process for upgrading the KVM switch’s firmware.  
The Utility comes as part of a Firmware Upgrade  
Package that is specific for each device. New  
firmware upgrade packages are posted on our  
web site as new firmware revisions become  
available. Check the IOGEAR web site regularly to  
find the latest packages and information relating  
to them.  
2. Choose the Firmware Upgrade Package you want to  
install (usually the most recent), and download it to  
your computer.  
3. Use the Firmware Upgrade Cable provided with this  
unit, to connect a COM port on your computer to  
the Firmware Upgrade Port of your switch.  
BeforeYou Begin  
To prepare for the firmware upgrade, do the  
following:  
1. From a computer that is not part of your KVM  
installation go to our support site and choose

Click Next to perform the upgrade. If you enabled  
Check Firmware Version, the Utility compares the  
device’s firmware level with that of the upgrade  
files. If it finds that the device’s version is higher  
than the up grade version, it brings up a dialog box  
informing you of the situation and gives you the  
option to Continue or Cancel.  
If you didn’t enable Check Firmware Version, the  
Utility installs the upgrade files without checking  
whether they are a higher level, or not. As the

Firmware Upgrade Recovery  
3. Use the Firmware Upgrade Cable (provided with  
this unit), to connect to a serial port on your  
computer with the Firmware Upgrade Port of the  
switch.  
There are basically two conditions that call for  
firmware upgrade recovery:  
• When you begin a firmware upgrade, but decide  
not to proceed with it.  
4. Plug the switch’s power adapter cable back in.  
5. Follow the upgrade procedures that begin with the  
Starting the Upgrade section (p. 39).  
• When the Mainboard firmware upgrade fails.  
Note: If one of the cascaded switches fails to  
upgrade successfully, unplug it from the installation  
and perform the recovery and upgrade operation  
independently. After it has been successfully  
upgraded, plug it back into the installation.  
To perform a firmware upgrade recovery, do the  
following:  
6. After the upgrade completes successfully, unplug  
the switch’s power adapter cable, once again.  
7. Slide the Firmware Upgrade Recovery Switch back  
to the Normal position.  
8. Plug the switch’s power adapter cable back in. This  
completes the Firmware Upgrade Recovery  
operation, and your switch is ready for use.  
1. Unplug the switch’s power adapter cable.  
2. Slide the Firmware Upgrade Recovery Switch (see  
p. 8) to the Recover position.
