3.1 About Fast Switching
Older display devices required a longer time between the loss of one digital signal
and the introduction of another, as well as a physical disconnection of the
interconnecting cable in order to be able to detect and adjust to the new video
attributes and parameters. Normal switching, therefore, introduced a 5V signal
disconnection along with a delay in switching. Many newer display devices,
however, are now capable of “on-the-fly” switching.
Depending on the display device in use, the VS-44HN allows for fast switching
(minor reset and the connection kept alive) and extra fast switching (no reset and
the connection kept alive). Using the fast and extra fast switching modes allows for
fraction-of-a-second switching times when using high performance display devices
or when using a scaler on the video output.

3.3 Using the IR Transmitter
You can use the RC-IR3 IR transmitter to control the machine via the built-in IR
receiver on the front panel or, instead, via an optional external IR receiver (Model:
C-A35M/IRR-50). The external IR receiver can be located up to 15 meters away
from the machine. This distance can be extended to up to 60 meters when used
with three extension cables (Model: C-A35M/A35F-50).
Before using the external IR receiver, be sure to arrange for your Kramer dealer to
insert the internal IR connection cable (for example, P/N: 505-70434010-S) with
the 3.5mm connector that fits into the REMOTE IR opening on the rear panel.
Connect the external IR receiver to the REMOTE IR 3.5mm connector.

4. Press the EDID button.
The default EDID is stored on the selected input when the display returns to
normal.
6.3 Storing and Recalling a Switching Setting from a Preset
You can use the STO and RCL buttons to store up to 8 setups and then recall
them using the OUT (1-4) and IN (5-8) selector buttons (see Figure 4).
Figure 4: Store-Recall Button Configuration

VS-44HN - Operating the VS-44HN 4x4 HDMI Matrix Switcher
15
To store a switching setting (for example, to preset 8):

2. Press the STO button.
The STO button flashes.
3. Select an OUT or IN SELECT button to store the device setting (for example,
IN 4 for preset 8).
4. Press the STO button to store the current setup.
You have to press the STO button within 10 seconds or the procedure automatically
times out.
To recall a switching setting (for example, from preset 3):
1. Press the RCL button.
The RCL button flashes.
2. Press the relevant OUT or IN button that stored the preset (for example,
OUT 3/preset 3).
3. Press the RCL button to recall the stored preset.
The RCL button stops flashing.
6.4 Changing the Port Switching Speed
The switching speed can be set per port to any of the following:
3—Normal (default)
2—Fast
1—Extra fast
To change the port switching speed:
1. Ensure that the device is in normal switching mode, (that is, not Store, Recall
or EDID mode).

16
VS-44HN - Operating the VS-44HN 4x4 HDMI Matrix Switcher
2. Press the RCL and EDID buttons at the same time.
The RCL and EDID buttons flash, and the display indicates the switching
speed mode of each port.
IN 1, IN 2 and IN 3 are illuminated (red).
3. Press one or more (or ALL) of the OUT buttons to select the port to change.
The selected port setting on the LED display flashes.
4. Press one of the IN 1/IN 2/IN 3 button to toggle the switching speed, (to Extra
fast/Fast/Normal, respectively).
The switching speed displayed changes for the selected ports.
5. Press the LOCK button to confirm the change.
The switching speed for the selected port is changed and the device reverts
to the normal switching mode.
Note: If the LOCK button is not pressed within about 12 seconds, the device exits
the port speed switching mode automatically and all changes are lost.
6.5 Setting HDCP to On/Off
HDCP support can be enabled (On) or disabled (Off) for each of the HDMI inputs,
allowing the source to transmit a non-HDCP signal if required (for example, when
working with a Mac computer)
To set the HDCP:
1. Turn the power off on the machine.
2. Press and hold the IN 1, IN 2 and LOCK buttons simultaneously and turn the
power on while pressing these buttons (you will need more than one person
to perform this step).
The machine is set to the HDCP enable/disable mode.
The input front panel buttons’ status indicates the HDCP state of each input:
HDCP enabled (ON) on an input –that input button is illuminated
HDCP disabled (OFF) on an input –that button is not illuminated

17
3. Press an input button to change its status.
You can press one or more inputs.
4. Once you have changed the status of HDCP on the inputs as desired, press
the EDID to save the changes and exit the HDCP enable/disable mode to
return to normal operation.
Note: If the EDID button is not pressed within about 12 seconds, the device exits
the port HDCP On/Off mode automatically and all changes are lost.
6.6 Resetting the IP Parameters
This procedure resets only the IP related parameters. All switching and
preset values remain unchanged.
To reset the IP parameters to their default values (see Section 9):
Press and hold the RESET button on the rear panel while powering up the
device
6.7 Switching Between Protocol 2000 and Protocol 3000
To switch from Protocol 2000 to Protocol 3000 and back again using the
front panel buttons:
1. On the TO OUTPUT 1 row, press Output buttons 1 and 3 at the same time.
Protocol 3000 is active.
2. On the TO OUTPUT 1 row, press Output buttons 1 and 2 at the same time.
Protocol 2000 is active.
Note that when sending consecutive protocol commands make sure to
maintain at least a 200ms delay between commands.
After performing EDID get/store commands, a 1 sec delay is required
before sending another protocol command.
