Quad View (DDC Mode)

To expand your installation from Dual View displays to Quad view displays, you can use the DDC Mode

port to connect two GCS1642 / GCS1644 units together. After doing so, you will be able to congure the

quad displays video settings on the computer in extended mode or Mirrored mode.

To set up DDC mode, power off all devices, refer to the installation diagram on the next page.

1. Connect all the computers to the Host as described in Hardware Setup, Cable Connection on page 18.

2. On the Client, using two custom DVI Dual Link cables, plug the DVI connectors into the DVI sockets A
and B in the same KVM port section of the switch.

3. At the other end of the two custom DVI Dual Link cables, plug the monitor cable into the respective
ports on the computer.

4. Repeat steps 2 and 3 for all computers.

5. On the rear of the second GCS1644, set the DCC switch to Client.*

Firmware Upgrade

Note: In order to perform a rmware upgrade, you need to use a computer that’s not connected to the

KVM.

Step 1

Make sure that the power adapter is connected to the KVM. Shut down all other computers connected to
the GCS1642A / GCS1644A installation, except the computer connected to port 1.

Step 2

If you have a Quad View installation, remove the cable connected to the DCC port, which connects the
two GCS1642A / GCS1644A units, and set both DCC switches to Host.

Step 3

Invoke Firmware Upgrade Mode (see Firmware Upgrade Mode, page 23). The front panel LEDs ash

together to indicate Firmware Upgrade Mode is in effect.

Step 4

Remove keyboard and mouse from the KVM, then plug these into the computer connected to port 1.

Step 5

Choose the Firmware Upgrade Package you want to install you downloaded from the IOGEAR website for
the GCS1642A / GCS1644A.

27

Step 6

Read the License Agreement and click “I
Agree” then click “Next” if you wish to continue

with the rmware upgrade. Otherwise, click

“Cancel” to exit.

28

Step 7

Choose the correct KVM that you wish to

perform rmware upgrade from the “Device

List” and then click “Next” to continue. Then
the Firmware Upgrade Utility will verify if there
is a KVM connected to the computer by the
firmware upgrade cable. (Check Firmware
Version checkbox is optional)

29

Step 8

If you have checked the “Check Firmware Version” checkbox, then the utility will check the current rmware
that is on your KVM. If the current rmware is newer than the rmware that you wish to upgrade to, a window

will popup and prompt you to ask if you wish to proceed. Simply click “Yes” to start the upgrade and “No”
to cancel the upgrade.

Note: If you did not check the “Check Firmware Version” checkbox, utility will perform the upgrade

automatically no matter what version of rmware you have in the KVM.

30

Step 9

When the rmware upgrade is done, you will

see “Firmware upgrade OK” in the “Status
Messages” window. Then simply click “Finish”
to complete the whole firmware upgrade
process.

Final Step

Now the KVM will reset by itself and it will be
ready for usage after the rest.

31

Upgrade Fail

If the Upgrade Succeeded screen doesn’t appear, it means that the upgrade failed to complete successfully.
In this case you should do the following:

Step 1

Power off the CS1642A / CS1644A by removing the power jack.

Step 2

Invoke Firmware Upgrade Mode by holding down the Mode Selection push button on the front panel
(see Mode Selection Push button, page 9) and power on the CS1642A / CS1644A. The orange LEDs

ash together.

Step 3

Go through the rmware upgrade procedure again.
