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 video, audio, presentation, and broadcasting professionals on a daily basis.
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 i 2.1 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).
2.2 Safety Instructions ! 2.3 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.
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.
3.1 Defining the RC-76R/RC-78R Room Controllers This section defines the RC-76R/RC-78R.
# Feature 11 RESET Button Function Press to reset to factory default definitions: IP number 192.168.1.39, Mask – 255.255.0.0, Gateway – 0.0.0.0 First, disconnect the power supply and then connect it again while pressing the Reset button.
4 Connecting the RC-76R/RC-78R i Always switch off the power to each device before connecting it to your RC-76R/RC-78R. After connecting your RC-76R/RC-78R, connect its power and then switch on the power to each device. To connect the RC-76R/RC-78R as illustrated in the example in Figure 2: 1. Connect the IR outputs as follows: Connect an IR emitter to IR OUTPUT 1 and attach the emitter to the DVD player 1 Connect an IR emitter to IR OUTPUT 2 and attach the emitter to the DVD player 2 2.
Figure 2: Connecting the RC-76R/RC-78R Room Controllers 4.1 Connecting RS-232 Devices You can control up to two AV devices such as a projector or an RS-232 display by connecting them to the RC-76R/RC-78R via their RS-232 connection. To connect a device to the RC-76R/RC-78R via RS-232: Using a straight cable, connect pin 2 to TX, pin 3 to RX and pin 5 to GND on the RS-232 terminal block connector of the RC-76R/RC-78R 4.
Connect the A (+) pin of the device to the A pin on the RS-485 terminal block of the RC-76R/RC-78R Connect the B (-) pin of the device to the B pin on the RS-485 terminal block of the RC-76R/RC-78R Connect the G pin of the device to the GND pin on the RS-485 terminal block of the RC-76R/RC-78R If your device is the first or last device on the line, slide the RS-485 termination switch up otherwise make sure it is set to down (see Figure 1). 4.
4.4 Connecting the K-NET Port The K-NET port is wired as shown in Figure 3. Figure 3: K-NET PINOUT Connection If your device is the first or last device on the line, slide the K-Net termination switch up otherwise make sure it is set to down (see Figure 1). 4.5 Grounding the RC-76R/RC-78R 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 4 defines the grounding screw components.
To ground the RC-76R/RC-78R: 1. Connect the ring tongue terminal to the building grounding point wire (a green-yellow, AWG#18 (0.82mm2) wire, crimped with a proper hand-tool is recommended). 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 Operating the RC-76R/RC-78R You can operate your RC-76R/RC-78R using: 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 www.kramerelectronics.com 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 12 The built-in Web server.
6 Front Panel Button Caps and Labels The RC-76R/RC-78R are supplied with a button label sheet and 6/8 clear, button caps to house the labels. Figure 5 illustrates a sample button label sheet.

6.1 Installing the Front Panel Button Caps and Labels To install the button caps and labels: 1. Remove the required labels from the supplied button label sheet. 2. Unscrew the Decora front plate from the device. Put the plate and screws aside. 3. To access the buttons, remove the two button cover plate mounting screws (see Figure 6) and remove the button cover plate. Put the plate and screws aside. Figure 6: Removing the Button Cover Plate Mounting Screws 4. Lift each cap away from its button. 5.
Figure 7: Button Cap Orientation with Label 6. Retaining the orientation, return each cap to its correct button. Figure 8: Replacing the Button Cap 7. Repeat for all caps. 8. Replace the button cover plate and screw it into place with its mounting screws. 9. Replace the Decora face plate over the unit and screw it into place with its mounting screws.
