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.

The RC-74DL Master Room Controller features:

• 12 configurable, RGB backlit, front panel buttons in three groups

(configured usi ng the K-Config configuration software

1

• 1 configurable rotary up/down controller with direction indicator LEDs

(configured usi ng the K-Config configuration software)

)

• 2 general purpose I/O ports that can be configured by K-Config as

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

• 2 K-NET™ control channels

2

• 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

5.2 Connecting the Ethernet Port

The Ethernet connection of the RC-74DL lets you perform all control
functio ns of the RC-74DL over the Internet using a PC running the Kramer
Site-CTRL control program.

To connect the RC-74DL to a network:

1. Connect the Ethernet port of the RC-74DL to the Ethernet port on a
network hub or network r oute r, vi a a st raight cabl e with RJ-45 connectors.

2. At the other end, connect the Internet to a PC ru nning Site-CTRL.

3. After connecting the Ethernet p ort, you have to install and config ure it.
For detailed instructions on how to install and configure your Ethernet
port, see the K-Config Software Guide available from our Web site

6 Grounding the RC-74DL Master Room Controller

The gro unding screw is used to earth the chassis of the unit to the building
ground preventing static electricity from impacting the performance of the
unit.

Figure 5 and Table 3 defines the grounding s crew components.

Figure 5: Grounding Connection Components

Table 3: Grounding Component

Descriptions

# Component Description

1 M3X6 screw
2 1/8" Toothed Lock Washer
3 M3 Ring Tongue Terminal

To ground the RC-74DL:

1. Connect the Ring Tongue terminal to the buildi ng ground ing point wire
(it is recommended to use a green-yellow AWG#18 (0.82mm

2

) wire,

crimped with a proper hand-tool).

2. Insert the M3x6 screw through the toothed lock washers and the tongue
terminal in the order sho wn a bove.

3. I ns ert the M3x6 screw (with the two toothed loc k washers and ring
tongue terminal) into the grounding screw hole and tighten t he screw.

7 Operating the RC-74DL Master Room Controller

You can operate your RC-74DL using:

• Front panel buttons. These are configured using the K-Config software.

For instructions on using the software, see the K-Config Software Guide
available from our We b site
