  Congratulations on purchasing your Kramer RC-74DL Master Room Controller, which is ideal for the following typical applications:

• Controlling multimedia rooms, such as classrooms, auditoriums, conference rooms, and so on

• Enabling remote control and management of AV equipment

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, and application programs, and to check if firmware upgrades are available (where appropriate).

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, 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.

Safety Instructions

• Caution: There are 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

Recycling Kramer Products

• The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC aims to reduce the amount of WEEE sent for disposal to landfill or incineration by requiring it to be collected and recycled. To comply with the WEEE Directive, Kramer Electronics has made arrangements with the European Advanced Recycling Network (EARN) and will cover any costs of treatment, recycling, and recovery of waste Kramer Electronics branded equipment on arrival at the EARN facility. For details of Kramer’s recycling arrangements in your particular country go to our recycling pages at www.kramerelectronics.com/support/recycling/.

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 software for network remote 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

Connecting the RC-74DL

• Always switch off the power to each device before connecting it to your RC-74DL. After connecting your RC-74DL, connect its power and then switch on the power to each device.

To connect the RC-74DL, as shown in Figure 3 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 4.3) as follows:
   • Connect RS-232 port 1 to the projector
   • 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, the RC-63DL).
7. Connect the 12V DC power adapter to the RC-74DL power socket and to the mains electricity.

Connecting the RS-232 Interface

To connect an AV device to the RC-74DL using the RS-232 port, connect the RS-232 9-pin D-sub port on your AV device to the RS-232 terminal block on the rear panel of the RC-74DL as shown in Figure 4.

RS-232 Device

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 on our Web site.

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.
• Figure 5 shows the grounding screw 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 (0.82mm2) 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.

Operating 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 on 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 Website

Retrieving the RC-74DL Current IP Address

• You can retrieve the RC-74DL current IP address by connecting it to 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 the connection method to USB:
6. Click Connect.
   • Figure 8: K-Config 3 Device Settings WIndow
   • Figure 9: K-Upload Device Properties
   • The current RC-74DL IP address appears.

Front Panel Button Caps and Labels

Installing the Front Panel Button Caps, Labels

To install the button caps and labels:

1. Remove the required labels from the supplied button label sheet.
2. Hold the button cap so that it is oriented as shown in Figure 10 with the “wings” on the left and right sides.
3. Insert the label inside the cap.
4. Retaining the orientation, place the button cap on the buttons of the
   • RC-74DL.
5. Repeat for all caps.
6. Remove the protective foils from both sides of the Perspex (acrylic glass) windows.
7. Place the faceplate on the RC-74DL so that the four screw mounting holes are aligned.
8. Insert the four mounting screws and tighten them with a screwdriver.
