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-12 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-12 - Overview
3 Overview
The SL-12 is a highly versatile controller that acts as an all-in-one control
processor 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-12 features:
An Ethernet port for controlling several AV products over ETH
4 general purpose I/O ports that can be configured as analog inputs, digital
inputs, or digital outputs for interfacing with a variety of devices such as
sensors, switches, LEDs, and relays
4 bidirectional RS-232 ports that control AV equipment such as projectors,
LCD and PDP displays, power amplifiers, switchers and scalers
8 relay contact closure ports that control other room items related to the AV
system such as raising and lowering drapes, the screen or the projector
IR control on three inputs (one built-in receiver and two IR inputs on 3.5mm
mini jacks) and four outputs (terminal blocks)
IR Learning that learns commands from any IR remote
1 RS-485 serial port
Compatibility with Kramer Site-CTRL software for network remote control
and management over the Ethernet port
A K-NET™ control channel that connects compatible user interfaces and
supplies power and control data over a single cable
A USB port for uploading a configuration file
Status LEDs for all functions
Flexible control via Ethernet, K-NET™, RS-485, IR receiver and external IR
commands

4.1 Using the RC-4 IR transmitter
You can use up to two optional RC-4 IR transmitters as auxiliary control panels
and initiate configured control triggers—refer to the K-Config guide—via the built
in IR receiver on the front panel, and/or via the optional external IR receiver
(C- A35M/IRR) that exists in several cable lengths.
4.2 IR Input Functionality
The SL-12 front panel includes one built-in receiver and two IR inputs on 3.5mm
jacks (shown in Figure 3) for control via the RC-4.
Figure 3: SL-12 IR Inputs
These three IR inputs can be set up differently, as shown in the following table:
Status
Operation in K-Config
None of the external IR receivers are connected:
RC-4 controls the unit through the
built-in receiver
Define IR-1 –RC-4 as the
auxiliary device and set the
triggers
An external IR receiver is connected to IR Input 1:
One RC-4 controls the unit through
the built-in receiver and a second
RC-4 unit controls the unit through
the IR Input 1 external IR receiver:
Define IR-2 –RC-4 as the
auxiliary device for the built-in
receiver and set the triggers
Define IR-1 –RC-4 as the
auxiliary device for the
external IR receiver

An external IR receiver is connected to IR Input 2:
One RC-4 controls the unit through
the built-in receiver and a second
RC-4 unit controls the unit through
the IR Input 2 external IR receiver:
Define IR-1 –RC-4 as the
auxiliary device for the built-in
receiver and set the triggers
Define IR-2 –RC-4 as the
auxiliary device for the
external IR receiver
connected to IR INPUT 2 and
set the triggers
Two external IR receivers are connected to IR Input 1
and IR input 2, respectively:
One RC-4 controls the unit through
the IR Input 1 external IR receiver
and a second RC-4 unit controls the
unit through the IR Input 2 external
IR receiver:
Define IR-1 –RC-4 as the
auxiliary device for the
external IR receiver
connected to IR INPUT 1 and
set the triggers
Define IR-2 –RC-4 as the
auxiliary device for the
external IR receiver
connected to IR INPUT 2 and
set the triggers
The built-in IR receiver is disabled
Note: when using two IR receivers, take care to place them in
separate locations to prevent one IR receiver accepting transmissions
that are sent to the other IR receiver.
4.3 Connecting the RS-232 Interface
To connect an AV device to the SL-12 using the RS-232 port, connect the RS-232
9-pin D-sub port on your device to the RS-232 terminal block on the rear panel of
the SL-12 as shown in Figure 4:
