2.1 Achieving the Best Performance
To achieve the best performance:
•Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
•Do not secure the cables in tight bundles or roll the slack into tight coils
•Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
•Position your Kramer VS-41HC away from moisture, excessive sunlight and
dust

6 VS-41HC - Overview
3.2 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 (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.

4.1 Using the PC and DVD Modes
The VS-41HC has two operation modes that can be set individually for each input:
the PC mode (default) and the DVD mode:
•Use the PC mode when connecting one or more computers to the inputs
using a DVI-to-HDMI converter cable
For example, the Kramer HDMI-DVI gold-plated cable in various lengths (3”, 6”, 10” and
15”).
•Use the DVD mode when connecting one or more DVDs to the inputs
In the PC mode, an input always has access to the EDID (default or acquired) to
prevent the computer from resetting if the output is not connected.
In the DVD mode, an input only has access to the EDID when it is switched to the
connected output.

VS-41HC - Connecting the VS-41HC 9
The PC mode and the DVD mode can be applied to a single unit or to several
inputs. For example, if you want to connect computers to INPUTS 1 and 2, and
DVD machines to INPUTS 3 and 4, set INPUTS 1 and 2 to the PC mode and
INPUTS 3 and 4 to the DVD mode.
To set the inputs to either the PC or DVD mode, do the following:
1. Turn off the VS-41HC power.
2. Press the PANEL LOCK button while turning the power on again.
3. Keep pressing and holding the PANEL LOCK button for a few seconds and
then release it.
The LOCK button flashes.
If an input button illuminates, this indicates that that input is set to the DVD
mode.
If an input button is not illuminated, this indicates that that input is set to the
PC mode.
4. Press an input to toggle between the PC mode (input button not illuminated)
and the DVD mode (input button illuminated).
5. To exit this mode, press the PANEL LOCK button.
6. Connect a computer to the input that is set to the PC mode and a DVD to the
input that is set to the DVD mode.
The following table summarizes the differences between the PC mode and the
DVD mode:

The input EDID source is the default EDID
or an acquired EDID (see Section 5.1) The input EDID source is acquired directly
from the connected output
