2 RC-52A - Getting Started

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

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).

2.1 Achieving the Best Performance

To achieve the best performance:

•Use only good quality connection cables to avoid interference, deterioration

in signal quality due to poor matching, and elevated noise levels (often

associated with low quality cables)

•Avoid interference from neighboring electrical appliances that may adversely

influence signal quality

•Position your Kramer RC-52A away from moisture, excessive sunlight and

dust

Caution: No operator serviceable parts inside the unit

Warning: Use only the Kramer Electronics input power wall

adapter that is provided with the unit

Warning: Disconnect the power and unplug the unit from the wall

before installing

RC-52A – Overview 3

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. The IR commands that are learned are used for the customized

control of external sources, receiving the IR commands from different remote

transmitters without the need for an external IR remote control unit.

By connecting to the USB port, each button can be assigned, using K-Config (see

USection 5U), with a trigger including up to eight actions (serial and/or IR and/or set

light and/or lock and/or delay, see USection 5.2U)

The RC-52A is available in European (80mm and 86mm height versions) and

American versions.

The RC-52A also features:

•Remote analog audio level control

•Button lighting configuration

•A front panel lock that can be unlocked by a secret code which can be set by

the configuration application

In addition, the RC-52A supports:

•Start up, timeout, and schedule macros

•Power supply over USB during configuration

•IR repeating through its IR receiver

4 RC-52A - Overview

3.1 Defining the RC-52A Room Controller Front Panel

The RC-52A is available in three versions (see Figure 1): 80mm and 86mm for

Europe and a version for the United States:

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. Connect the RS-232 port (see Section 4.1

4. Connect the audio potentiometer PINs to the remote control terminal block

connectors of a power amplifier (for example, the Kramer 912 Power

Amplifier, see

) to the projector.

Section 4.2

5. Connect the 5V DC power adapter to the RC-52A power socket and to the

mains electricity.

4.3 Connecting the IR-OUT

Figure 6 shows how to connect the Kramer IR emitter (3.5mm to IR Emitter Control

Cable, P/N: C-A35/IRE-10). The white striped side connects to IR OUT, the black

side connects to the Ground, and the LED Emitter Shell is affixed to the IR sensor

window with the adhesive layer.

Figure 6: IR Emitter Wiring

4.4 Using the RC-52A as an IR Repeater

Once the RC-52A is mounted and powered, and the IR emitter is connected to a

piece of A/V equipment (for example, a DVD), you can use it as an IR signal

repeater, to extend the IR signal to that machine, which has no direct line-of-sight

(see Figure 7).
