RV-M7 Data Radio Modem Technical Manual
General Information about the RV-M7
Congratulations on your purchase of a M7 radio modem – the most advance UHF radio modem available today.
Please take a few minutes to read this manual carefully. The information presented here will allow you to derive maximum performance from your radio modem. After reading it, keep the manual handy for quick reference, in case questions arise later on.
Besides the fuse, there are no user-serviceable points inside this transceiver. All service work must be referred to your Authorized Service Center or Raveon Technologies Service Department.
WARNING - DO NOT operate theRV-M7-U radio modem when bystanders are within 2 feet (.6 meters) of the antenna.
Blasting Caps and Blasting Areas
To avoid possible interference with blasting operations, turn off this radio or remove the DC power when you are near electrical blasting caps, in a blasting area, or in areas posted: “Turn off two-way radio.” Obey all signs and instructions.
Potentially Explosive Atmospheres
Turn off your radio prior to entering any area with a potentially explosive atmosphere. Do not install this product for use in areas with potentially explosive atmospheres. Do not remove, install, or charge batteries in such areas. Sparks in a potentially explosive atmosphere can cause an explosion or fire resulting in bodily injury or even death.
Note: The areas with potentially explosive atmospheres referred to above include fueling areas such as below decks on boats, fuel or chemical transfer or storage facilities, areas where the air contains chemicals or particles, such as grain, dust or metal powders, and any other area where you would normally be advised to turn off your vehicle engine. Areas with potentially explosive atmospheres are often but not always posted.
Antennas used for this transmitter must not exceed an antenna gain of 0 dBd. The radio modem must be used in fixed vehicle-mount configurations or at fixed base-station sites. It is not intended for portable applications.
This radio is restricted to occupational use, work related operations only where the radio operator must have the knowledge to control the exposure conditions of its passengers and bystanders by maintaining the minimum separation distance of following range. Failure to observe these restrictions may result in exceeding the FCC RF exposure limits.
Antenna Installation:
For rear deck trunk installation, the antenna must be located at least the following range away from rear seat passengers and bystanders in order to comply with the FCC RF exposure requirements.
For model RV-M7-UC-x:
Radiated frequency and Distance
RV-M7-UC (450-480MHz 5 watts)
1.97 Feet (0.6 m)
FCC ID: SRS-RV-M7-UC
Raveon Technologies Corporation
For vehicular roof top installation, the antenna must be placed in the center of the roof.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
NOTE: The manufacturer is not responsible for any radio or TV interference caused by unauthorized modifications to this equipment. Such modifications could void the user’s authority to operate the equipment.
- Reorient or relocate the receiving antenna.
- Increase separation between the equipment and receiver.
- Connect the equipment to an outlet on a circuit different from which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician.
This product also complies with FCC Part 22, 90 and Part 95 Subpart J of the FCC rules and regulations.
The Federal Communications Commission (FCC), with its action in ET Docket 93-62, has adopted a safety standard for human exposure to Radio Frequency (RF) electromagnetic energy emitted by FCC-certified equipment. This product meets the uncontrolled environmental limits as stated in OET-65C (01-01) when operated in accordance with the operation guidelines described in this manual. Proper operation of this radio device according to the instructions in this publication will result in user exposure substantially below the FCC recommended limits.
This equipment generates, uses, and radiates radio frequency energy, and if not installed and used in accordance with the instructions, may cause harmful interference. However, there is no guarantee that interference will not occur. If this equipment does cause interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to correct the interference by one of the following measures:
Overview
The M7 RF data radio is a rugged high-performance, high-speed narrow-band data modem. It contains a receiver, a transmitter, and modem, creating an easy-to-use transparent data radio link. The M7’s user interface is asynchronous RS-232 data into and out of the M7 (CMOS level optional). Modem operation is virtually transparent to the user and the configuration of the modem is via the user serial port.
Unlike any other radio modem on the market, the M7 may be operated in either a “Packetized Mode” or a “Streaming Real-Time Mode”. There are advantages to each approach, and your choice depends upon how your system operates.
For privacy and network versatility, the M7 incorporates a 16 bit identification code. Its protocol also uses a 16bit CRC to guarantee the integrity of the data. Perfect for SCADA and telemetry applications, the M7 can be used for simple point-to-point data communication applications, or for more sophisticated point-to-multipoint, peer-to-peer, or mesh networks.
Although the M7 is the easiest to use modem on the market, its re-programmability makes it extremely versatile. Most parameters within the modem may be re-configured to optimize it for specialized operations, extended range, or higher data throughput.
- High-speed over the air data rates. 19200bps in 25kHz channel, 9600bps in 12.5kHz.
- Built-in radio transceiver with integrated modem
- Easy to use. Plug-in, Turn-on, and GO. Transmit data in = Receive data out.
- Lowest current draw in industry.
- Wide input voltage with high-efficiency switching voltage regulator.
- Integrated Packet data protocol and built-in Streaming Real-Time operation.
- ARQ error correction and retransmission capability. Totally transparent to the application.
- Capable of store-and-forward repeating operation.
