Introduction

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. In recent years, we have redesigned and upgraded

most of our line, making the best even better! Our 1,000-plus different models

now appear in 11 groups1

Thank you for purchasing the Kramer RC-74DL Master Room Controller,

which is ideal for controlling multimedia rooms, such as classrooms,

auditoriums, conference rooms, and so on, while enabling remote control

and management of AV equipment.

that are clearly defined by function.

Each package includes the following items:

•The RC-74DL Master Room Controller

•3 Gang US Installation mud ring

•Power supply and this user manual2

2 Getting Started

We recommend that you:

•Unpack the equipment carefully and save the original box and

3 Overview

The RC-74DL is a highly versatile, 3 gang US, master room controller that

acts as an 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.

Overview

The RC-74DL Master Room Controller features:

•12 configurable, RGB backlit, front panel buttons in three groups

(configured using the K-Config configuration software1

•1 configurable rotary up/down controller with direction indicator LEDs

(configured using the K-Config configuration software)

)

•2 general purpose I/O ports that can be configured by K-Config as

digital inputs, digital outputs or analog inputs for interfacing with a

variety of devices such as sensors, switches, LEDs, or relays

•3 bidirectional RS-232 ports that can control AV equipment such as

projectors, LCD and PDP displays, power amplifiers, switchers and

scalers

•4 relay contact closure ports that can control other room items related to

the AV system, such as, raising and lowering drapes, a screen or a

projector

•IR control on 2 outputs (terminal blocks)

•IR Learning that learns commands from any IR remote

•Compatibility with Kramer Site-CTRL software for network remote

control and management over the Ethernet port

•2 K-NET™ control channels2

•Flexible control via Ethernet and K-NET

that connect compatible user interfaces

and supply power and control data over a single cable

To achieve the best performance:

•Connect only good quality connection cables, thus avoiding 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 and position

your RC-74DL away from moisture, excessive sunlight and dust

To connect1Figure 3the RC-74DL, as shown in the example in , do the

following:

1. Connect the IR outputs as follows:

Connect an IR emitter to IR OUTPUT 1 and attach the emitter to the

DVD player

Connect an IR emitter to IR OUTPUT 2 and attach the emitter to the

power amplifier

2. Connect the RS-232 ports (see Section 6

) as follows:

Connect RS-232 port 3 to the plasma display

3. Connect the RELAY terminal block connectors as follows:

Connect RELAY 1 and 2 to the screen

Connect RELAY 3 and 4 to the lighting system

4. Connect the GPI/O 1 port to a motion detector.

5. Connect the Ethernet port to a network (not shown in Figure 3).

6. Connect the K-NET port to any RC device with K-NET (for example,

5.2 Connecting the Ethernet Port

The Ethernet connection of the RC-74DL lets you perform all control

functions of the RC-74DL over the Internet using a PC running the Kramer

Site-CTRL control program.

To connect the RC-74DL to a network:

1. Connect the Ethernet port of the RC-74DL to the Ethernet port on a

network hub or network router, via a straight cable with RJ-45 connectors.

2. At the other end, connect the Internet to a PC running Site-CTRL.

3. 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 Software Guide available from our Web site1
