Confi guration port
g
Confi g (host control) port — This is a front panel version of the rear panel
Host Control port (the 9-pin D connector), and it is independent of that port.
This port makes it possible to upload and confi gure device drivers and also to
initiate IR learning via a front panel connection after the MLC has been installed.
Connect a Windows-based PC or an RS-232 control system to this 2.5 mm
mini stereo-style (tip-ring-sleeve) connector. You can use the Extron 9-pin D
to 2.5 mm stereo mini TRS RS-232 cable (part #70-335-01) or make your own
cable. See page 2-4 for a wiring diagram and port protocol.
N
This port requires 38400 baud communication, a higher speed than many other
Extron products use. The MLC confi guration software automatically sets
the connection for the appropriate speed. If using HyperTerminal or a similar
application, make sure the PC connected to these ports is set for 38400 baud.
N
Extron recommends confi guring and controlling the MLC via the LAN
connector. Ethernet connections are faster and more reliable.
Optional Control Modules and IR 402 Remote Control
The MLC can “learn” IR commands from a VCR’s, DVD’s, tape deck’s or other
device’s remote control, allowing you to create an IR driver fi le that can be
incorporated into the MLC’s event scripts. A command can be associated with
each of the buttons on an optional infrared control module (such as the Extron
IRCM-VCR, IRCM-DVD, IRCM-DVD+, or IRCM-DV+) in order to allow limited
control of source devices. ACM control modules provide limited remote control of
adjustments to a slaved MediaLink Switcher (MLS).
A total of four control modules (a maximum of four control
module addresses) can be installed with this MLC. Refer to the
Control Modules User’s Manual and the IRCM-DV+ Control
Module User’s Manual for installation details. See chapter 4 of
this manual for special instructions for the IRCM-DV+.
