There is no password protection on
this interface and, by default, the
RS-232 port is enabled. However, the
administrator has the ability to disable
the serial control port from the Web
Portal.
See below for a list of the available commands.
For more information on external control, please refer
to the MediaPOINTE Command Line Interface document.
Telnet
The telnet client within the DMR HD provides access
to the Command Line Interface through the TCP/IP
protocol. By default, telnet is disabled but can
be activated from the Web Portal with an optional
password. The available commands are the same as
listed in the RS-232 section.
To access the telnet client, open a command prompt on
your computer and enter: telnet
Once connected to the DMR HD, a connect message will
be displayed.

Infra-Red
The Infra-Red (IR) receiver for the remote control is
located on the front of the DMR HD. It can also be
used for IR control via control systems such as AMX or
Crestron.
Remote Contact Closure (Relay)
A relay contact closure connection is mounted on the
back as a 1/8th (3.5mm) phone plug. Either a mono or
stereo plug can be used, but in the case of the stereo
phone plug, short the sleeve to the ring as the negative
connection. This connection can be wired to a simple
switch closure and will start or stop a recording.
Note: There is a +5V on the tip
This closure can be in the form of a relay, manual
switch or semi-conductor switch. This allows for relay
control via external control systems such as AMX,
Crestron, or by a plain momentary trigger, such as a
footswitch.
Semi-conductor closures are found on AMX or Crestron
controllers in the form of a D I/O port. If using a semi-
conductor closure, polarity is important. The phone
plug tip must be wired to the + or individual input of
the D I/O port, and the sleeve connected to the ground
or - connector. Note that, unlike relay connections,
these connections are not isolated and can form
grounding or hum loops.
