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-74DL 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 neighboring electrical appliances that may adversely

influence signal quality

• Position your Kramer RC-74DL away from moisture, excessi ve sunli ght 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.

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.

The RC-74DL features:

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

using the K-Config configuration software)

Available from Kramer Electronics on our Web site at

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

• 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 s oftware for net work remot e control

and management over the Ethernet port

• 2 K-NET™ control channels that connect compatible user interfaces and

supply power and control data over a single cable

K-NET™ is a proprietary Kramer protocol for interconnecting Kramer units

• Flexible control via Ethernet and K-NET

4.2 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 o th er 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 site.

4.3 Grounding the RC-74DL

The grounding screw is used to earth the chassis of the unit to the building ground
preventing static electricity from impacting the performance of the unit.

10 RC-74DL - Connecting the RC-74DL

Figure 5

shows the grounding screw components.

Figure 5: Grounding Connection
Components

To ground the RC-74DL:

1. Connect the Ring Tongue terminal to the building grounding point wire (it is
recommended to use a green-yellow AWG#18 (0.82mm

2

) wire, crimped with

a proper hand-tool).

2. Insert the M3x6 screw through the toothed lock washers and the tongue
terminal in the order shown above.

3. Insert the M3x6 screw (with the two toothed lock washers and ring tongue
terminal) into the grounding screw hole and tighten the screw.

5 Ope rating the RC-74DL

You can operate your RC-74DL using:

• The front panel buttons. These are configured using the K-Config software.

For instructions on using the software, see the K-Config Software Guide
available from our Web site

• A PC running Site-CTRL control software:

To operate your device using Site-CTRL, see the Site-CTRL User Guide
available at the Kramer Web site

5.1 Retrieving the RC-74DL Current IP Address

You can retrieve the RC-74DL current IP address by connecting it t o your PC via
the USB port using either Kramer K-Config or K-Upload software.

To retrieve the current IP Address:

1. Connect the 12V DC power adapter to the RC-74DL power socket and to the
mains electricity.

2. Wait for RC-74DL to complete initialization (the front panel buttons flash and
LED labels appear).

3. Connect the PROGRAM USB port to your PC.

4. Open K-Config/K-Upload.

5. Click Connect and set connection method to USB:
