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
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.

before installing
2.3 Recycling Kramer Products
!
The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC
aims to reduce the amount of WEEE sent for disposal to landfill or incineration by
requiring it to be collected and recycled. To comply with the WEEE Directive,
Kramer Electronics has made arrangements with the European Advanced
Recycling Network (EARN) and will cover any costs of treatment, recycling and
recovery of waste Kramer Electronics branded equipment on arrival at the EARN
facility. For details of Kramer’s recycling arrangements in your particular country

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

1. Connect the RELAY terminal block connectors as follows:
Connect RELAY 1 and 2 to the projector lift
Connect RELAY 3 and 4 to the screen
Connect RELAY 5 and 6 to the blinds
Connect RELAY 7 and 8 to the lighting system
2. Connect the GPI/O ports as follows:
Connect GPI/O 2 to motion detector 1
Connect GPI/O 4 to motion detector 2
3. Connect the IR outputs as follows:
