KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview
4
 Digital microphone input level control and digital master audio level
control
 Microphone talk-over mode
1
 A CAT 5 output, with a transmission range of more than 300 feet (over 100
meters) that transmits VGA/UXGA signals
2
to a remote acceptor via a
receiver
 An internal 5-Watt per channel (24kHz, 3dB) power amplifier for
connecting the speakers directly to the machine
 A panel LOCK button to prevent tampering with the front panel
 Recall of the previous setup from non-volatile memory
 Audio output level change (via RS-232)
3.1.2 Understanding the Media / Room Controller Section
The Media/Room Controller section controls A/V equipment—especially
projectors and associated equipment
3
—in media rooms (such as classrooms,
boardrooms, or auditoriums), as well as room functions such as lights, blinds,
a projector lift and/or a screen motor.
The VP-23RC Media/Room Controller section includes:
 Eight configurable buttons to set up any supported commands
 An Ethernet port
4
for configuration and control
 Two bidirectional RS-232
5
serial ports for universal display (for example,
projectors) and control of the VP-23RC (or other) switcher
 Four relays for the simplified and centralized control of room functions
(such as lights, blinds, screen settings, and so on). The relays have
normally open (NO) and normally closed (NC) contacts
 Three IR control ports
 An IR-learner for the customized remote transmitters, without the need for
an external unit IR remote control
 Macro mode operation, for programming up to 15 commands with the
press of a single button
 Firmware upgrade support
1 The microphone input signal lowers the line audio output level when the connected microphone detects sound
2 Excludes audio
3 Including the A/V equipment connected to the VP-23RC Presentation Switcher section
4 Also for controlling the Presentation Switcher section
5 The RS-232 terminal block port (item 14 in Figure 3) is also used for firmware upgrade
