RC-76M/ RC-712M - Getting Started
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
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-76M/RC-712M 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.

4 Installing the RC-76M/RC-712M
To install the RC-76M/RC-712M:
Configure the buttons
Connect the cables
Mount the room controller onto the Merten compatible housing
Attach button caps with labels
Place the frame
Attach the faceplates
4.1 Configuring the Room Controller Buttons
We recommend that you configure the buttons before mounting the
device onto the Merten compatible on-wall box.
4.2 Mounting the Device
This section describes how to mount the RC-76M/RC-712M onto the Merten
compatible on-wall box (sold by Kramer, P/N: OWB-2G/M).
4.2.1 Connecting the Ports
The following diagrams illustrate a compatible 2 gang on- wall box, but installation
is similar with any compatible wall box.
We recommend that you first detach the male connectors from the rear
panel, connect the relevant wires to them and then reconnect the
assembled male terminals to the unit just before installation in the on-wall
box.

Configure the 6 buttons for RC-76M and 12 buttons for RC-712M using the
K−Config configuration software via the USB port that is located on the front panel
on the board or the Ethernet port located on the rear panel. Use the IR learning
receiver on the front panel to read IR commands from any IR remote control. Note
that the device needs to be connected to the power to configure the buttons. The
K-Config user guide is available on our Web site at

Pass the appropriate cables through any of the four housing cable
pass-through openings on the sides of the box (see Figure 3).
Figure 3: Merten Compatible Housing
Always switch off the power to each device before connecting it to your
RC-76M/RC-712M. After connecting your RC-76M/RC-712M, connect
its power and then switch on the power to each device.
Although the illustration in Figure 4 shows the RC-712M, the following example
applies also to the RC-76M.
To connect the RC-76M/RC-712M as illustrated in the example in Figure 4:
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 4.2.1.1) as follows:
Connect RS-232 port 1 to the projector
Connect RS-232 port 2 to the plasma display

4.2.1.1 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-76M/RC-712M via their RS-232 connection.
To connect a device to the RC-76M/RC-712M 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-76M

4.2.1.2 Connecting RS-485 Devices
You can control up to one AV device by connecting it to the RC-76M/RC-712M via
its RS-485 connection.
To connect a device to the RC-76M/RC-712M via RS-485:
Connect the A (+) pin of the device to the Apin on the RS-485 terminal block
of the RC-76M/RC-712M
Connect the B (-) pin of the device to the Bpin on the RS-485 terminal block of
the RC-76M/RC-712M
Connect the G pin of the device to the GND pin on the RS-485 terminal block
of the RC-76M/RC-712MRC-76M
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-76M/RC-712M lets you perform all control
functions of the RC-76M/RC-712M over the Internet using a PC running the
Kramer Site-CTRL control program to control AV devices.
To connect the RC-76M/RC-712M to a network:
1. Connect the Ethernet port of the RC-76M/RC-712M 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.

4.4 Connecting the K-NET Port
The K-NET port is wired as shown in Figure 5.
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 Mounting the RC-76M/RC-712M onto the Merten Housing
After the cables are connected you can mount the device onto the housing. Note
that the illustrations in this section do not show the cables that are already
connected to the device and passing through the housing cable openings.
To mount the RC-76M/RC-712M:
1. Reconnect the detachable terminals to the rear panel
2. Gently place the RC-76M/RC-712M inside the housing, making sure that all
cables remain connected.
