Overview

3 Overview
The RC-7B / RC-7BE is a highly versatile controller interface panel for the
control of A/V equipment in any multimedia room, especially the control of
a projector or other display device, via RS-232 and/or IR emitter cable. The
RC-7B / RC-7BE is 12V DC fed. The RC-7B is a one-gang wall plate. The
RC-7BE is two-gang wall plate intended for the European market.
In particular, the RC-7B / RC-7BE features:
VOLUME Up and VOLUME Down buttons
ON, OFF, PC, DVD and VCR buttons, each of which can be
programmed to carry out up to 15 commands, in sequence, with one
press of a button
In addition, the RC-7B / RC-7BE includes:
Two IR ports
Two RS-232 serial ports for universal display
An RS-485 serial port
A 3.5mm CONFIG jack connector on the front panel for RS-232
configuration and control
An IR learner on the front panel for the customized control of external
sources, absorbing the IR commands from different remote transmitters
Control via the front panel buttons, and remotely, via RS-232
To achieve the best performance:
Connect only good quality connection cables, thus avoiding
interference, deterioration in signal quality due to poor matching, and
elevated noise- levels (often associated with low quality cables)
Avoid interference from neighboring electrical appliances and position
the RC-7B / RC-7BE away from moisture, excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit1.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.

The example in Figure 6 shows a rear view perspective of a typical RC-7BE
configuration. It connects to the projector via RS-232. Each source—the PC,
DVD and VCR—connects to the dedicated video and audio inputs of the
projector:

Figure 7 shows the RC-7BE built into a podium in an auditorium with an
overhead projector and a cabinet with a VCR and a DVD inside, all
controlled via the RC-7BE. The presenter’s laptop is located on the podium,
next to the RC-7BE. It is also controlled by the RC-7BE and is used for
presentations and slide shows.

5.2 Using the Macro Buttons
Pressing any button initiates a macro sequence1, during which the button
blinks (as programmed by the system integrator). If during the macro
sequence the button blinks faster than usual2, this indicates that a malfunction
has been detected3 and the RC-7B / RC-7BE exits the macro sequence.
To stop a macro sequence, press and hold that button for 5 seconds. The
sequence will come to an end. You can resume operation by pressing any of
the buttons4. The unit will carry out the macro sequence commands from the
beginning.
5.3 An Example of Operating the RC-7B / RC-7BE
Figure 8 shows an example of how to operate the RC-7B / RC-7BE:
Figure 8: RC-7B / RC-7BE Operation Example
1 The macro sequence can be carried out instantly or can take a while, depending on the delay times included in the sequence
2 Six times per second, as compared with twice per second during normal operation
3 For example, when pressing ON to power up the projector while the projector is still in the power down process
