of unique, creative,and affordablesolutions to the vast range of problems that confrontthe
video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we
have redesigned and upgraded most of our line, makingthe best even better!
Getting Started
We recommendthat you:
•Unpack the equipment carefully and save the original box and packaging materials for
possible future shipment.
•Reviewthe contents of this user manual.
Go to www.kramerav.com/downloads/VS-42H2tocheck forup-to-date user manuals,
application programs, and to check if firmwareupgrades are available (where appropriate).
Achieving Best Performance
•Use only good quality connection cables (we recommendKramerhigh-performance,
high-resolution cables) to avoid interference, deterioration in signal quality due to poor
matching, and elevated noise levels (oftenassociated with low quality cables).
•Do not secure the cables in tight bundles or roll the slack into tight coils.
•Avoid interferencefrom neighboring electrical appliances that may adversely influence
signal quality.
•Position your Kramer VS-42H2 away from moisture, excessivesunlight and dust.
Safety Instructions
Caution:
•This equipment is to be used only inside a building. It may only be connected to other
equipment that is installed inside a building.
•For products with relay terminals and GPI\O ports, please referto the permitted rating
for an external connection, located next to the terminal or in the User Manual.
•There are no operator serviceable parts inside the unit.
Warning:
•Use only the power cordthat is supplied with the unit.
•To ensure continuous risk protection, replace fuses only according to the rating
specified on the product label which located on the bottom of the unit.

Typical Applications
VS-42H2 is ideal for the following typical applications:
•ConferenceRooms.
•Education.
•Sports Bars.
•Restaurants.
•Casinos.
•HomeTheaters.
Controlling your VS-42H2
Control your VS-42H2 directly via the front panel push buttons (with on-screen menus), or:
•By RS-232 serial commandstransmitted by a touch screen system,PC, or other serial
controller.
•Remotely,from the infrared remote-control transmitter.
•Via the Ethernet using built-in user-friendly web pages.
Using the IR Transmitter
You can use the RC-IR3IR transmitter to control the machine via the built-in IR receiveron
the front panel or, instead, viaan optional external IRreceiver. The external IR receivercan
be located up to 15m away from the machine. This distance canbe extended to up to 60m
when used with three extension cables.
Beforeusing the external IR receiver,be sure to arrange for yourKramerdealer to insert the
internal IR connection cable with the 3.5mm connectorthat fits into the REMOTEIRopening
on the rear panel. Connect the external IR receiver to the REMOTEIR 3.5mm connector.
