2 Getting Started
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 www.kramerav.com/downloads/RC-43SL 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 neighbouring electrical appliances that may adversely influence signal quality
- Position your RC-43SL 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.
2.2 Safety Instructions

Caution: There are no operator serviceable parts inside the unit
Warning: Use only the Kramer Electronics power supply that is provided with the unit
Warning: Disconnect the power and unplug the unit from the wall 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 go to our recycling pages at http://www.kramerav.com/support/recycling/.
3 Overview
The RC-43SL is a highly versatile, 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. It features a keypad with six touch-sensitive, backlit buttons.
Using the Kramer K-Config software, each button on the RC-43SL can be programmed on the room controller with a function, where each function can combine multiple individual actions.
The RC-43SL features:
- 6 touch-sensitive, backlit buttons with indicator LEDs
- 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 for controlling other room items such as raising and lowering drapes, the screen or the projector.
- IR control - 2 outputs (terminals blocks), 1 sensor
- IR learning with one sensor that learns commands from any IR remote
- 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 - Configures with K-Config software
- Compatibility with Kramer Site-CTRL™ software for network remote control and management over the Ethernet port
• 1 gang US wall plate size

| 12 | RELAYS Terminal Blocks | Connect to low-voltage relay-driven devices (from 1 to 3) |
4 Connecting the RC-43SL

Always switch off the power to each device before connecting it to your RC-43SL. After connecting your RC-43SL, connect its power and then switch on the power to each device.

You do not have to connect all the inputs and outputs, connect only those that are required.

Do not connect the power to the unit until after the front plate is mounted.
To connect the RC-43SL as illustrated in the example in Figure 2:
- Connect the RELAY terminal block connectors as follows:
■ Connect RELAY 1 and 2 to blinds
■ Connect RELAY 3 to a screen
- Connect the IR outputs as follows:
■ Connect IR OUTPUT 1 to DVD player 1
■ Connect IR OUTPUT 2 to DVD player 2
- Connect the RS-232 ports as follows:
■ Connect RS-232 port 1 to a projector
■ Connect RS-232 port 2 to a display
-
Connect the Ethernet port to a network.
-
Connect the K-NET port to any RC device (in this example, an RC-63D) over K-NET.

4.1 Setting the DIP-Switches
DIP-switches are located at the bottom of the K-Net terminal block connector.
To access the DIP-switches, remove the K-Net connector.
With the unit upright and the K-Net connector in the upper right corner:
- The left-hand DIP-switch is reserved for internal use.
- The right-hand DIP-switch is the K-Net terminator.
If the K-Net line ends here, slide the switch up for 120Ω termination.
If the K-Net line continues to another device, slide the switch down.

Figure 3: RC-43SL DIP Switches
4.2 Connecting the RS-232 Port
To connect an AV device to the RC-43SL, connect the RS-232 9-pin D-sub port on your device to the RS-232 terminal block on the rear panel of the RC-43SL controller as shown in Figure 4:
![RS-232 Device Pin 5 Ground Pin 3 Rx Tx Pin 2 FS-43SL RS-232 [RX1 TX1 G RX2 TX2]](/content/2026/05/999114/images/2f05c88bcd13983405770f10620a5a9058f6b9a52900d28db8a0d4fdbc7cac5b.jpg)
Figure 4: RS-232 Connection
4.3 Connecting the Ethernet Port
The Ethernet connection of the RC-43SL allows you to perform all control functions of the RC-43SL over the Internet using a PC running the Kramer Site-CTRL control program.
To connect the RC-43SL to a network:
- Connect the Ethernet port of the RC-43SL to the Ethernet port on a network hub or network router, via a straight cable with RJ-45 connectors.
- Over the network, connect to a PC running Site-CTRL.
After connecting the Ethernet port, you have to install and configure it. For detailed instructions on how to install and configure your Ethernet port, see the K-Config Configuration Guide available for download at the Kramer Web site:
http://www.kramerav.com.
4.4 Installing the Front Panel Buttons
The RC-43SL is supplied with preprinted buttons from which you can choose the six that best represent the functions you wish to assign the buttons.
To install the front panel buttons:
- Remove the cover plate by carefully prying it away from the printed circuit board (PCB) frame using a small screwdriver being careful not to damage it.
- Remove the stock buttons from the front panel.
- Insert the buttons into the front panel taking care to ensure that they are oriented correctly.
- Place the PCB and frame onto the front panel ensuring that the mounting orientation tongue is in line with the cutout on the front panel.
- Press the front panel and PCB frame together securely.

Each time the front panel is removed and remounted you must recalibrate it by powering off and powering on the unit.
4.5 Connecting the K-NET Port

Do not connect the power to the unit until after the front plate is mounted.
The K-NET port is wired as shown in Figure 5.
