We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
Review the contents of this user manual
Go to http://www.kramerelectronics.com/support/product_downloads.asp
to check for up-to-date user manuals, application programs, and to check if
firmware upgrades are available (where appropriate).
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 SL-1N away from moisture, excessive sunlight and
dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

SL-1N - Overview
3 Overview
The SL-1N is a highly versatile controller; an all-in-one extended remote control
panel for control of AV equipment—especially projectors and associated
equipment—in any room (such as classrooms, boardrooms, or auditoriums). It
streamlines operations and simplifies control by integrating audio, video, and
computer-video sources into a centralized system.
The SL-1N features:
2 bidirectional RS-232 ports to control AV equipment such as projectors,
LCD and PDP displays, power amplifiers, switchers and scalers
3 relay contact closure ports to control other room items related to the AV
system such as raising and lowering drapes, the screen or the projector
IR control - 1 input (3.5mm) and 2 outputs (terminals blocks)
IR Learning that learns commands from any IR remote
Compatibility with Kramer Site-CTRL™ software for network remote control
and management over the Ethernet port
A K-NET™ control channel for connecting compatible user interfaces and
supplying power and control data over a single cable
A USB port for loading device firmware
Flexible control using Ethernet, K-NET™, IR sensors and external IR
commands.

4 Connecting the SL-1N
Always switch off the power to each device before connecting it to your
SL-1N. After connecting your SL-1N, connect its power and then
switch on the power to each device.
To connect the SL-1N, as the example in Figure 2 illustrates, do the following:
1. Connect the RELAY terminal block connectors as follows:
Connect RELAY 1 and 2 to blinds
Connect RELAY 3 to a screen
2. Connect the IR outputs as follows:
Connect IR OUTPUT 1 to DVD player 1
Connect IR OUTPUT 2 to DVD player 2
3. Connect the RS-232 ports as follows:
Connect RS-232 port 1 to a projector
Connect RS-232 port 2 to a display
4. Connect the IR sensor as follows:
Connect IR INPUT to an IR sensor
5. Connect the Ethernet port to a network.
6. Connect the K-NET port to any RC device (in this example, an RC-63D) over
K-NET.
