RC-52A – Overview 3
3 Overview
The RC-52A is a 2 gang room controller with an analog volume control adjustment
knob, an RS-232 port, an IR control port and six backlit and label capable buttons
with three levels of lighting intensity available (set via the K-Config application). It
sends an RS-232 or IR command—with the push of a button—to a device (such as
a projector, display or switcher) via serial control protocols.
The RC-52A includes a front panel built-in IR Receiver for IR-command learning
and IR repeating. The IR commands that are learned are used for the customized
control of external sources, receiving the IR commands from different remote
transmitters without the need for an external IR remote control unit.
By connecting to the USB port, each button can be assigned, using K-Config (see
USection 5U), with a trigger including up to eight actions (serial and/or IR and/or set
light and/or lock and/or delay, see
USection 5.2U)
The RC-52A is available in European (80mm and 86mm height versions) and
American versions.
The RC-52A also features:
• Remote analog audio level control
• Button lighting configuration
• A front panel lock that can be unlocked by a secret code which can be set by
the configuration application
In addition, the RC-52A supports:
• Start up, timeout, and schedule macros
• Power supply over USB during configuration
• IR repeating through its IR receiver
