M2115 OWNERS MANUAL
Solutions for Advancing Communications
USB-A and USB-B Ports [4.2]
There are two USB ports available for connecting various devices to the M2115 mobile and most base units. There is a
USB-A style connector on the front panel of the radio that will allow the connection of a flash memory stick to either
read/write configuration information, save audio in a base station application, or save GPS data when used in mobile
applications. There is also a USB-B style connector on the right side of the radio that allows an M2115 to connect to a
PC. Users may configure an M2115 remotely through the use of a PC program. Configuration information is either
entered into a simple-to-use graphical interface, or is read in from a file that contains configuration information
downloaded to a PC from an M2115. Once the information is loaded into the graphical interface, the user may then load
the configuration information into the M2115 over the USB-B port. This makes configuring the radio quick and easy as no
front panel operation is needed to program the M2115. Another use of the USB-B port is for when two radio boards are
installed in the M2115. When used in tandem with an LMR radio PC application data may be sent over the UHF radio link
to the base station for Business-to-Business (B2B) applications. Live (“real time”) GPS data may also be sent to a
dispatcher for vehicle tracking purposes (e.g.: optimal resource scheduling, etc…).
The LMR and GPS applications are
future implementations.
Rear Panel [4.3]
The rear panel includes a 12-pin power connector, two TNC style antenna connectors for radio cards 1 and 2, and an
optional GPS module. The radio includes a cover plate for the GPS interface when the GPS module is not in use. The
12-pin power connecter may also have wires for an external power amplifier, remote frequency control, external
microphone input, and/or external speaker output for base stations. If an external power amplifier is used, the number of
frequencies made available by remote selection goes from a maximum of 16 to a maximum of 7 channels as the power
amplifier uses two of the remote frequency selection lines. The 12-pin power connector implements functions that are
dependent on the type of M2115. The available options are as follows:
Mobile and Base Station Radios:
•
External speaker wire
•
12V-14V DC power supply
Base Station Radios (only):
•
External RF power amplifier monitoring wires (25W and 50W BS’s)
•
Remote frequency selection, remote PTT, and microphone input wires
Global Positioning System (GPS) [4.4]
Note: The GPS unit is a future option.
The Global Positioning System (GPS) is a satellite based system that allows an M2115 to know it’s location with an error
in horizontal distance of only 10.5 meters. The GPS module updates its position once every second and main controller
polls this data and uses it for reporting the position of the radio. Some users may want to know where their vehicles are in
real time (resource scheduling applications), while others may want to review their vehicles’ locations periodically.
Depending on whether the radio is a mobile, base station, or dual card radio determines what implementation may be
used with any given M2115. Mentor Radio’s live tracking system requires using the UHF LMR radio to send location data
in real time. Users with less stringent time requirements may have the radio set up to access the data by manually
extracting it with a flash memory stick (sold separately). The radio may store up to a week’s worth of GPS information.
The GPS module is sold separately from an M2115, and customers may install it themselves (
See Installation
).
