3 Overview
The RC-74DL is a highly versatile, 3 gang US, master room controller that
acts 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). It streamlines operations
and simplifies control by integrating audio, video, and computer-video
sources into a centralized system.
The RC-74DL Master Room Controller features:
12 configurable, RGB backlit, front panel buttons in three groups
(configured using the K-Config configuration software1)
1 configurable rotary up/down controller with direction indicator LEDs
(configured using the K-Config configuration software)
2 general purpose I/O ports that can be configured by K-Config as
digital inputs, digital outputs or analog inputs for interfacing with a
variety of devices such as sensors, switches, LEDs, or relays
3 bidirectional RS-232 ports that can control AV equipment such as
projectors, LCD and PDP displays, power amplifiers, switchers and
scalers
4 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
IR control on 2 outputs (terminal blocks)
IR Learning that learns commands from any IR remote
Compatibility with Kramer Site-CTRL software for network remote
control and management over the Ethernet port
2 K-NET™ control channels2 that connect compatible user interfaces
and supply power and control data over a single cable
Flexible control via Ethernet and K-NET
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
your RC-74DL away from moisture, excessive sunlight and dust

Avoid interference from neighboring electrical appliances that may
adversely influence signal quality
Position your Kramer RC-74DL away from moisture, excessive sunlight
and dust
