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 www.kramerav.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.

3 Overview
The RC-76R/RC-78R is a 6-button/8-button control keypad that fits into standard
1 gang US wall junction boxes. Connected over Ethernet to Site-CTRL™ remote
AV control, site management & monitoring system, as well as LAN-connected
control gateways for extended controlled devices capacity, and over KNET™ to
master room controller and auxiliary keypads for remote keypad control, it can
flexibly serve either as a standalone room controller, part of a multi-unit KNET™
system, or part of a multi-unit Ethernet system managed by the Kramer Site-
CTRL™ site management platform. The RC-76R/RC-78R have identical
functionality.
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
www.kramerav.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 design frame 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
Function is programmed by the K-Config

4 Connecting the RC-76R/RC-78R
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 3
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. Connect the RS-232 ports (see Section 4.1
Connect RS-232 port 1 to the projector
Connect RS-232 port 2 to the plasma display
3. Connect the RELAY terminal block connectors as follows:
Connect RELAY C and 1 to the screen
Connect RELAY C and 2 to the lighting system
4. Connect the GPI/O 1 port to a motion detector.
5. Connect the Ethernet port to a network.
) as follows:

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

Page 13
•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.
