3 Overview
The RC-74DL is a highly versa tile, 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.

digital inputs, digital outputs or anal og inputs for interfacing with a
variety of devices such as sensors, switches, LE Ds, or relays
• 3 bidirectio nal RS-232 ports that can control AV equipment s uch as
projectors, LCD and PDP displays, power amplifiers, switchers and
scalers
• 4 relay contact closure ports that can con trol 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 ove r the Ethernet port

• Flexible control via Ethernet and K-NET
that connect compatible user interfaces
and supply power and control data over a single cable
To achieve the best performance:
• Connect only good quality connection cables, thus avoiding interference,
deterioration in signal q uality 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 moi s ture, excessive sunlight and dust
