Mentor Radio Model M2115 refers to a family of fully frequency synthesized transceiver radios. Model M2115M refers to the vehicle mounted mobile version of the transceiver, while models M2115B and M2115B refer to the 10W watt base station version. Both the mobile and base station radios use the same core radio. However, there are several differences between them, which are as follows:

1.) Input power required: The M2115M requires 12-14 VDC, whereas the M2115B version operates off of an AC power source (115 VAC or 230 VAC). 2.) Microphone signals: The 500 ohm audio output signal is factory configurable. For mobiles, it is connected to the microphone jack for headset use. On the base unit, it may be connected to the rear panel for remote control connections. 3.) Remote interface: All base radios have remote control capability. The 12-pin rear power plug includes discrete signals for connecting to a variety of remote controls. 5 signal lines (F1 through F5 are available to allow remote frequency selection. Any one of up to 16 channels may be selected. On all base station units, a rocker style power switch on the rear of the base power supply unit controls the AC input power to the unit. A built-in fuse provides circuit overload protection and spare fuse is included in the power plug. The unit is provisioned with a D-shaped AC power plug to allow low cost international power cords to be connected to local AC power.

Radio Cards [4.1]

A M2115 may contain one or two radio cards, while the radio systems main controller is housed only on the VHF voice radio card operating in the 118.025 MHz 136.975 MHz VHF band. Therefore, all M2115s must have this radio card installed. Expanded functionality may be given to the radio by adding a second radio card. Each radio will have its own separate antenna connector on the rear panel which allows for simultaneous dual band operation. The second radio card may operate in one of several bands planned for integration into the M2115 unit. The first radio card to be introduced will be a UHF FM LMR radio operating in the 450-470MHz band for voice and low speed data. As technology progresses, radios in different frequency bands offering diverse functionality will be developed and made available for the second card slot. USB-A and USB-B Ports [4.2]

There are two USB ports available for connecting various devices to the M2115 mobile and 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 a mobile application. There is also a USB-B style connector on the right side of the radio that allows an M2115 to connect to a PC. A user 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:

External speaker wire Mobile and Base Station Radios:

12V-14V DC Power Supply Base Station (BS) Radios (only):

External RF Power Amplifier Monitoring wires (25W and 50W BSs) Remote Frequency Selection, Remote PTT, and Microphone Input wires Phone: 216-265-2315 Fax: 216-267-2915 www.mentorradio.com (10/11) 7 Wireless Solutions for Advancing Communications M2115 OWNERS MANUAL 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 its 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 Radios 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 weeks worth of GPS information. The GPS module is sold separately from an M2115, and customers may install it themselves (See Installation). Receiver [4.5]

The M2115 receiver is a dual conversion super heterodyne with frequency synthesized local oscillators. The first local oscillator (LO1) is 400 MHz above the carrier frequency and the second local oscillator (LO2) is set to 800 MHz. The process for receiving a signal is as follows:

The received signal is mixed with LO1 where only the ~400 MHz mixing product is kept. All other frequencies including those from other channels are filtered out except for the adjacent channels. The resulting signal will henceforth be called MIX1. LO2 is divided by two inside an IQ modulator and mixed with MIX1 to yield two different signals. These two signals are the I and Q baseband components of the received RF signal. All other unwanted frequencies from adjacent channels are filtered out during this process. The I and Q baseband signals go through separate analog-to-digital conversions (ADC) inside a Digital Signal Processor (DSP) and the voice/data is then fully demodulated inside the DSP. o o If the radio card is a VHF/UHF voice radio, then the DSP passes the voice information to the radios main microcontroller. The voice audio is then sent to the local speaker and/or to an external speaker by way of filtered ~9-bit pulse-width modulation (PWM). The audio level may be adjusted from the front panel, and may even be shut off completely if desired. The squelch level and channel frequency may also be adjusted from the front panel. If the radio card is a UHF data radio, then the data may sent to a PC over the USB-B port and/or saved to a flash memory stick. While receiving, the radio cannot be transmitting as well. Since transmit supersedes receive, pressing the PTT will cause any signal that is being received on the current channel to be cut off from being sent to the M2115s speaker(s). By default, the radio is in receive mode and will send audio to the speaker at all times when not in transmit mode so long as the squelch level is set to 0%. Setting the squelch level above 0% will always cut out noise being sent to the speaker when there is no audio being received. Each saved channel has its own squelch setting, so make sure to set each channel to the squelch level desired. To see how to adjust the squelch level to get rid of noise or unwanted distant signals, see Screen Control.

General Operation [4.6.1]

There are multiple power output levels for the transmitter, where each channel has a unique power setting. There are 0W, 1W, 5W, and 10W output power settings that may be set using the front panel for the M2115M. For the 25W and 50W base stations, the power setting selection changes accordingly but still implements different settings. The 0W setting disables the transmitter and so the M2115 functions as a receive-only device in this case. When the microphone push-to-

talk switch is pressed from the remote controller or front panel the microprocessor detects it, shuts down the receiver, and then enters transmit mode. It does not matter what screen on the display a user is on in order to go into transmit mode, but the user will have the message TRANSMIT appear on the upper left side of the screen if on the main screen. Also note that all front panel operations are disabled when in transmit mode. Hot Microphone Detection [4.6.2]

There is a hot-microphone automatic shut down function that kicks in after 30 seconds of continuous transmitter on time which is useful for when a user has accidentally has the PTT in a pressed state while they are not present. Base Station PTT Operation [4.6.3]

For base station radios, the audio input that is used depends on which PTT is pressed when a remote interface is installed. The remote audio input is used when the remote PTT is pressed, and the local audio input is used when the local PTT is pressed. If the PTT is pressed from the remote controller AFTER the PTT has been pressed from the local controller, the PTT from the remote controller is ignored by the main processor. Any audio put on the remote controller audio line is also ignored. If the remote controllers PTT was pressed first, the same procedure holds true. High Voltage Standing Wave Ratio (VSWR) Detection [4.6.4]

While in transmit mode, the M2115s transmitter output is applied to forward and reverse power detector circuits. This allows the radio to keep the power output stable while transmitting. The radio cards processor can also detect if the PA breaks or prevent the PA from breaking by shutting it off when the reflected power voltage reads too high (VSWR) when transmitting. The front panel display shows VSWR when on the main screen when a high reflected power is detected to let the user know that the transmitter has been turned off due to high VSWR. A user may disable this feature altogether, although it is not recommended (see VSWR). AM Modulation Control [4.6.5]

For voice radios, the AM modulation index can be as high as 95% and will never go over 100% due to processor monitoring and control while under normal operation. All radios in this family are capable of operating at 100% duty cycle. Front Panel Control [4.7]

Overview [4.7.1]

The M2115 front panel control consists of a power on/off momentary button, a power status LED, four menu buttons, an optical rotary encoder with built in push button, a USB-A port, a USB-B port, a graphical liquid crystal display (GLCD), and a locking microphone/headset jack. Each M2115 radio includes a handheld noise canceling microphone with a heavy duty 5-pin XLR locking connector. 5-Pin XLR Locking Microphone/Headset Connector [4.7.2]

The M2115 can be configured to operate with a headset using a headset adapter which may be purchased through Mentor Radio. A Bluetooth adapter which is also sold through Mentor Radio may be connected to this plug and allows a user to use nearly any off-the-shelf Bluetooth headset on the market. The adapter comes with a wireless PTT so that the user needs to buy only the Bluetooth headset from a third-party vendor. Phone: 216-265-2315 Fax: 216-267-2915 www.mentorradio.com (10/11) 9 Wireless Solutions for Advancing Communications M2115 OWNERS MANUAL Power Control Button [4.7.3]

The power for the M2115 is controlled by a front panel momentary power on-off button. This is the button that is directly underneath the green LED on the front panel. Pressing the power on-off button while the radio is off will turn the radio on which will be apparent by the illumination of the green LED. Of course, the radio must have a power supply connected or nothing will happen. Also, if the radio turns off instantly, then the button was not held down long enough. To turn the radio off, it is highly recommended to only use the method that uses power on-off button. This is done by holding the power on-off button down for about 3 seconds while the radio is in receive mode. The green LED will turn off to indicate the main processor is trying to shut the radio down. The radio will only fully turn off after the button is released. If the radio is non-responsive to the button press, then the radio may need to be shut down by turning the power supply off. This method should only be used if absolutely necessary as configuration data may be lost. Menu Buttons [4.7.4]

Pressing a menu button changes either some value on the screen or changes what screen a user is viewing entirely. Menu buttons are referred to menu buttons 1-4, going from left to right when looking at the front panel head on (see the front panel diagram for visuals). Text above each button describes what each button will do on any given screen, while the high VSWR override functionality is accessible from every screen and only requires that a user is not in transmit mode to change the state. Rotary Knob [4.7.5]

The rotary knob serves several purposes on some screens and none on others. Most uses are for increasing or decreasing the value of a selected field on a screen, but that is not all it is used for. When there is a screen that includes an Enter and/or Exit menu option, users may press the rotary knob once for Enter and twice for Exit. Each screen uses the rotary knob differently. See the individual screens for rotary knob functionality in its entirety. Internal Speaker [4.7.6]

A 2x2 speaker is mounted on the bottom panel on the M2115M for mobile applications. A 3.5x2 speaker is mounted on the front panel of the power supply for base station units. The M2115B also includes an interface for a variety of remote control connections. Phone: 216-265-2315 Fax: 216-267-2915 www.mentorradio.com (10/11) 10 Wireless Solutions for Advancing Communications M2115 OWNERS MANUAL VSWR [5]

VSWR is an acronym for Voltage Standing Wave Ratio. VSWR is a measure of the ability of the transmitter to radiate RF power through the antenna and into open space compared to the signal that is reflected back into the transmitter. The more reflected power that does not leave the antenna, the higher the chance that there is excess energy may damage the transmitter components. Therefore, it is very important to shut down the transmitter when there is a high reflected power to help prevent damage to the transmitter. Under normal operating conditions, the transmitter is shut down when a high VSWR is read. Recognizing that there are times in the aviation industry where communications capability may be the difference of life and death, Mentor Radio has provided the ability to override the high VSWR transmitter shut down function of the M2115. To disable the high VSWR transmitter shut down function, a user needs only to hold down menu buttons 1 and 3 for around 3 seconds while the radio is powered up and in receive mode. Realize that if the PA blows up when VSWR control is overridden, then any warranty is instantly void. To re-enable the high VSWR control function hold down buttons 1 and 3 for another 3 seconds. It does not matter what screen that a user is on to enable or disable the override, but the main screen shows that the control is disabled by displaying OV on the upper left of the screen. When a high VSWR is encountered, a user should cut the power to the radio and inspect/ repair the transmission line as soon as possible.

Notice [5.1]

The first consideration for installation is to choose a suitable location. For both mobile and base installations, installation of the M2115 radio requires connecting the radio to a suitable antenna and a suitable power source. NOTICE: For geographic locations where lightning is prevalent, Mentor Radio recommends installing a lightning protector on the antenna coax. If used as a base station radio, another lightning protector on the AC line is recommended. M2115M [5.2]

The M2115M is intended to be installed into a vehicle. A suitable location should be selected to allow viewing of the GLCD and access to the front panel controls. A mounting bracket is provided that will allow mounting the M2115M under the dash or on any flat surface. The bracket may be installed above or below the radio. Mobile antennas are available in two versions; a thru-hole type and a magnetic mount type. Installing a thru-hole requires drilling a hole in the vehicle or mounting on a hood or roof of a vehicle. Magnetic mount antennas require routing the coax through the vehicle door where water may leak in or where the coax may be pinched. This may shorten the life of the antenna. Therefore, it is recommended to use a magnetic mount antenna for short term applications where the antenna may be removed and a thru-hole type for a permanently mounted antenna. Install the antenna and connect to the antenna connector on the rear panel. Some antennas for aviation band frequencies come with a UHF connector. In this case, a UHF to TNC adapter may be used to connect the antenna to the radio. The M2115M includes a built in speaker. However, an external speaker may be used with or instead of the internal speaker. If an external speaker is to be used, install 18 AWG wires to the power plug as follows: Green wire to pin 12

(Speaker audio out signal) and a black wire to pin 2 (GND). A power cable is available which includes a 6 foot speaker cable. External speakers and cables sold separately. Verify that the vehicle power is no greater than 14VDC. Connect the power cable to the vehicle power or battery (Red to

+, Black to -). Connect the 12-pin connector to the rear of the M2115M radio. M2115B [5.3]

The M2115B can rest on a shelf or a desk. Since this unit contains a cooling fan, when located on a desk or shelf do not place equipment, papers, magazines, etc. where they would restrict air flow through the left and right side vent ports thereby reducing its cooling. Install a suitable power cord for local power used. A line replaceable fuse is inside power plug. To remove the fuse, the cord must be removed first which is done with lightly prying pressure. The exposed fuse is the operating fuse and a spare fuse is located inside the fuse holder tray. The antenna connector is a TNC style connector. If the antenna coax does not mate with this type, adapters are available from Mentor Radio or from many electronic distributors. Connections for remote operation, when needed, are made via the 25 pin connector (type DB25) on the rear of the cabinet. Phone: 216-265-2315 Fax: 216-267-2915 www.mentorradio.com (10/11) 21 Wireless Solutions for Advancing Communications M2115 OWNERS MANUAL The antenna should be either a wideband type (118-137 MHz) or a narrow band type tuned to single channel or a very narrow range of frequencies. If a 3 or 6 dB gain antenna is used, communications range can be increased, because gain antennas effectively increase both receiver sensitivity and transmitter power. Care should be taken using gain antennas as many specify gain in a specific direction only. A directional antenna may reduce range in other directions in order to increase gain in a single direction. Depending upon your application, this may be acceptable. Low loss coaxial cable is also recommended, especially if the cable length exceeds 30 feet (10 meters). Plug the included microphone into the microphone jack on the front panel of the M2115. Be sure the plug is pushed all the way into the jack before turning the radio on. If remote operation is to be used, refer to the remote section in this manual. This information is provided for planning and installing remote controls to work with the M2115B. Global Positioning System (GPS) Module [5.4]

** To install the GPS module a #2 Philips Head screwdriver is required 1.) Remove the rear panel GPS module cover plate by unscrewing the two screws that hold the plate on. 2.) Press the GPS module connector onto the mating connector on the rear panel. Press firmly to ensure the connector is fully seated. 3.) Install cover plate over module and fasten the two screws removed from step 1. 4.) Install GPS antenna in a suitable location. Route antenna cable to radio. Connect to the GPS module mating connector (SMA style connector). NOTE: the GPS antenna must be exposed to the sky although placing it on a dashboard may be acceptable. For optimal sky view an externally mounted antenna is better. Review user requirements before deciding on antenna installation location. 5.) To enable the GPS feature of the radio, see the screen controls. ** This feature is not currently available.

Planning [5.5.1]

As a general guide and for basic system design planning purposes, the following may help you in your equipment requirement and selection process. Review Figure 1 for a summary of the pros and cons of each system. REMOTE Local Extension Control:

Tone Remote Control:

BENEFITS Less expensive controllers Not distance limited Easy to add controllers Uses low cost phone wire to connect between adapter and radios. Allows remote frequency selection No tools required to install units. DOWNSIDE Distance limited (<1K ft) Hard to add controllers Requires special expensive cable between each controller and radio. NO remote frequency selection Requires tools and technical skill to connect wires to a terminal board. More expensive controllers Requires a tone remote adapter Figure 1 - Comparison between Remote Control Systems Installation [5.5.2]

The M2115B provides the connections necessary at the rear panel 12-pin power plug. This plug contains all the connections needed for connecting various types of remote controllers to allow remote users to operate the M2115B base station radio. Each basic remote control type requires a different adapter cable to connect between the radio and the controllers. There are four basic styles of controllers available for connecting to the M2115B, which are:

1. Telephone Style handset 2. Desktop Style with a Pedestal Style Desktop microphone 3. Hands Free Voice Operated Transmit (vox) box 4. Dispatch style controller with a Gooseneck microphone Each of these 4 styles is available for both the local extension and tone remote controllers. Further, it is also possible to interface the M2115B to a dispatch console. Most consoles allow the interfacing many different types of radios and so make sure the M2115B is configured as an analog radio.

Connections to the mating connector may use #22 gauge wire. Note that there are four ground terminals and two terminals for the 4 ohm receiver audio output. The ground terminals may be used as needed for various remote connections; in some circumstances it may be desirable to double-up, using two ground pins in parallel (Each pin is rated for 1 ampere). The 4 ohm audio receiver outputs can be used with one 4 ohm or two 8 ohm external speakers. The +14 VDC is available to operate external remote control equipment. The 500/600 ohm receiver audio output can be used for remote stations or for a tape recorder output. Its level is factory adjusted to 0 dBm

(0.77 v rms) but may be adjusted internally for any level from -7 to +10 dBm by a trimmer potentiometer on the printed circuit board inside the M2115. The remote microphone audio input should be in the range -10 to -16dBm (0.3 to 0.15 V RMS). If this voltage is too high the modulation may be distorted when transmittingthat is, the voice transmissions may not sound as clear. Phone: 216-265-2315 Fax: 216-267-2915 www.mentorradio.com (10/11) 24 Wireless Solutions for Advancing Communications M2115 OWNERS MANUAL User Security Notice [6]

Mentor Radio has incorporated security into the M2115M and M2115B to help prevent inadvertent frequency changes that may result in unauthorized emissions. However, the M2115M and M2115B may be programmed without enabling security. Operating the M2115 radio without enabling security allows faster configuration changes but cannot help prevent unauthorized users from making inadvertent frequency changes that may potentially result in transmissions on unauthorized frequencies. It is up to the licensee or responsible person to determine if security is required for the M2115 radio. If more than one user is to operate the radio, Mentor Radio recommends that security be enabled. Enabling security requires adding at least one user to the radio. Once one or more users are entered into the configuration, no changes to the configuration are allowed until a user logs in. A prompt requests that a user enter his/her user identification (displayed on the LCD as USERID) and password. RF Exposure Affirmative Statement [7]

The M2115M and M2115B are restricted to occupational/controller use to satisfy FCC RF Exposure Limits. Use only authorized accessories and antennas. The use of non-authorized accessories or antennas may exceed FCC RF Exposure Limits. Maintenance [8]

No routine maintenance is necessary, other than to remove accumulated dust. If the equipment is accidentally impacted or dropped, operation should be fully checked and an internal inspection made for loose or broken parts. Servicing and Repair [9]

Should the M2115 require servicing, return it to us with a description of the problem. SERVICE SHOULD ONLY BE ATTEMPTED BY TECHNICIANS EXPERIENCED WITH THIS TYPE OF EQUIPMENT AND WHO HAVE AVAILABLE THE APPROPRIATE TEST EQUIPMENT. Phone: 216-265-2315 Fax: 216-267-2915 www.mentorradio.com (10/11) 25 Wireless Solutions for Advancing Communications M2115 OWNERS MANUAL Trouble Shooting and User Repair Guide [10]

In the event of a malfunction the following information may help isolate the malfunction to a line replaceable component. 1.) Unit will not turn on after pressing the power button.

- For a mobile installation check that the power connections are secure and verify the polarity is correct.

- For a base unit, verify that the fuse has not blown. A spare fuse is inside the fuse holder tray. 2.) LCD is hard to read in day light.

- Adjust the backlight setting to a more suitable level for your existing lighting condition. See screen. 3.) Radio has continuous noise when in receive mode.

- Adjust squelch level. Increase level until the noise stops. This is the point of maximum sensitivity squelched. It will be necessary to set this level for each operating channel.

- You may need to adjust to a lower setting if you are trying to receive very weak signals. 4.) The receiver volume level is set to low.

In normal operate mode the volume may be adjusted by rotating the front panel rotary knob while on the main screen. 5.) The unit tries to transmit then stops and the VSWR enunciator illuminates on the LCD.

- This is an indication that there is a malfunction in the transmission line (coax cable) or antenna. If this happens a qualified technician should check the cabling and antenna installation for the problem. 6.) The base unit is connected to a tone remote adapter, and remote operations fail to operate the radio properly.

- Try disconnecting the remote control and operate the M2115 locally. If the unit operates properly, replace the tone remote adapter. 7.) The wrong frequency appears on the main menu screen for a previously programmed channel.

- This is an indication that there may have been an inadvertent change in the configuration of the radio. If security is not enabled, enable it by adding a user. After security is enabled, only a user with a password can gain access to change configuration data. It is also possible that there was a firmware malfunction that the configuration needs to be reloaded. 8.) The volume is different from when the unit was last turned off.

- This is because the unit was not turned off from the front panel on-off button. Phone: 216-265-2315 Fax: 216-267-2915 www.mentorradio.com (10/11) 26 Wireless Solutions for Advancing Communications M2115 OWNERS MANUAL Licensing [11]
