About the MLC 226 Series MediaLink
™
Controllers
The Extron MLC 226 Series MediaLink
™
Controllers are capable of controlling a
projector and various other items such as lights, a projector lift, or a screen motor.
Throughout this manual they are referred to as the MLC 226, MLC, or controller.
All models offer RS-232 and IR-based projector (display) control along with IR or
serial control of other devices (typically A/V input sources); relays for controlling
items such as a projector lift, motorized projection screen, and lights; and RS-232
remote control of an Extron switcher.
• The IP models can be configured and controlled either via RS-232 serial
communication or via an Ethernet network using standard Internet protocol.
• The non-IP models have nearly all the features of the IP models, but they can be
configured and controlled via RS-232 only.
MLC 226 Series features
All models can be configured and controlledvia a host computer using RS-232
communication or via IP Link
™
Ethernet control. Setup and control can be
accomplished by simple ASCII commands (Simple Instruction Set, SIS
™
) or via the
included Windows
®
-based configuration program. The software offers many more
setup options than does SIS programming.
All models offer front panel controls. The optional IR 402 remote control and
optional SCP 226 Series hard-wired control pads can be used with the MLC, and
they mimic the MLC’s front panel controls.
Additional features for MLC 226 IP models
Via Ethernet/IP communication the MLC 226 IP models can make use of the
controller’s embedded Web pages, which include online diagnostics and
monitoring of basic control features. As an integrated part of the MLC 226 IP,
IP Link provides the following advantages:
Global compatibility — The switcher uses standard Ethernet communication
protocols, including ARP, DHCP, ICMP (ping), TCP/IP, Telnet, HTTP, and
SMTP.
Embedded Web page serving — The MLC 226 IP offers up to 7 MB of flash
memory for storing Extron and user-supplied Web pages, configuration
settings, and device drivers. Data in flash memory is served at a transfer rate
of 6 Mbits per second.
Multi-user support — Two hundred (200) simultaneous connections enable each
IP Link device to support many concurrent users and improve system
throughput by sending information in parallel.
Management ability via IP Link Global Viewer ver. 1.5 or later — The included
management application software allows you to control, monitor, and
schedule various functions of products connected to IP Link products.
E-mail notification — The MLC 226 IP can be set up to send an e-mail when the
projector has been disconnected or the projector’s lamp has been used for a
designated number of hours.
Controlling other devices
The MLC 226 Series offers two methods of projector and source device control:
RS-232 or infrared (IR). The MLC can learn IR signals from remote controls to
communicate with sources such as VCRs and DVD players. Users can create their
own device drivers (IR or RS-232) or go to the Extron Web site (www.extron.com)
to obtain device drivers.
