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 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 <ipaddress>
Once connected to the DMR, 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. 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.
