i
!
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
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

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.

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

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
4.2 Connecting RS-485 Devices
You can control up to one AV device by connecting it to the RC-76R/RC-78R via
its RS-485 connection.
To connect a device to the RC-76R/RC-78R via RS-485:
RC-76R/RC-78R - Connecting the RC-76R/RC-78R
9
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).
4.3 Connecting the Ethernet Port
The Ethernet connection of the RC-76R/RC-78R lets you perform all control
functions of the RC-76R/RC-78R over the Internet using a PC running the Kramer
Site-CTRL control program to control AV devices.
To connect the RC-76R/RC-78R to a network:
1. Connect the Ethernet port of the RC-76R/RC-78R 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.

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.
