RC-76R/RC-78R - 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)

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 RC-76R/RC-78R 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.

RC-76R/RC-78R - Overview

3 Overview

The RC-76R/RC-78R are highly versatile master room controllers that act 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). They streamline operations and simplify control by

integrating audio, video, and computer-video sources into a centralized system.

The RC-76R/RC-78R have identical functionality. The RC-76R has six buttons and

the RC-78R has eight buttons.

The RC-76R/RC-78R features:

6/8 configurable, RGB backlit, front panel buttons, configured using the

K-Config configuration software

Available from Kramer Electronics on our Web site at

http://www.kramerelectronics.com/support/?soft=k-config.

1 general purpose I/O port that can be configured by K-Config as a digital

input, digital output or analog input for interfacing with a variety of devices

such as sensors, switches, LEDs, or relays

2 bidirectional RS-232 ports that can control AV equipment such as

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

2 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

2 IR control ports with an IR learning receiver behind the front plate that

learns commands from any IR remote

1 RS-485 control 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, supply

power and control data over a single cable

Flexible control via Ethernet and K-NET

Decora compatible, wall plate size of 1 gang US
