1 Introduction Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis.
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 • Use Kramer high performance high resolution cables i 2.1 Go to http://www.kramerelectronics.com to check for up-to-date user manuals, application programs, and to check if firmware upgrades are available (where appropriate).
3 Overview The RC-52A is a 2 gang room controller with an analog volume control adjustment knob, an RS-232 port, an IR control port and six backlit and label capable buttons with three levels of lighting intensity available (set via the K-Config application). It sends an RS-232 or IR command—with the push of a button—to a device (such as a projector, display or switcher) via serial control protocols. The RC-52A includes a front panel built-in IR Receiver for IR-command learning and IR repeating.

4 Connecting the RC-52A Room Controller ! Always switch off the power to each device before connecting it to your Transmitter and Receiver pair. After connecting your Transmitter and Receiver pair, connect their power and then switch on the power to each device. To connect the RC-52A, as shown in the example in Figure 3, do the following: 1. Connect an IR emitter to IR OUTPUT 1 and attach the emitter to the DVD player. 2. Connect the DVD output to the input of a projector. 3.
