 The The RV-M7-U UHF GPS transponder with the weatherproof housing option (-WX) is a rugged high-speed UHF data modem with a built-in 12-channel GPS receiver. It has all of the features of Raveon's RV-M7 GX transponders as well as an IP65 weatherproof enclosure and connections. With up to 5 watts of RF power output, and operates as both a GPS transponder for tracking, and a radio modem for sending and receiving data.
The The M7 GX may be configured for a number of different GPS applications, including:
| Transponder: |
|
Periodically transmit position and status |
| GPS display: |
|
Connect M7 GX to a hand-held or mobile GPS, and icons will appear on the display showing the location of all other M7-GX radios in the system. |
| Radar Display: |
|
Radar Display: Connect M7-GX to a marine plotter or radar display, and icons will appear on the display showing the location of all other M7-GX radios in the system. |
| RavTrack PC: |
|
Connect the M7-GX to a personal computer running RavTrack PC (or other PC software) to view a map showing location, status, log movement, set alerts, and make reports from the data. |
As well as transmitting its position and status over the air, the M7-GX also has a radio modem with integrated RS232/422/485 interface for sending and receiving data.
For privacy and security, over-the air encryption is standard on every M7-GX radio. For network versatility, the M7-GX incorporates a 16-bit identification code, allowing up to 65,000 objects to be identified in one system. For wide-area coverage, all M7-GX transponders may be set to store-and-forward messages from other M7-GX transponders. Although the M7-GX is the easiest to use modem on the market, and makes the easiest to set-up Automatic Vehicle Locations (AVL) system available, 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.
The transponder may be programmed and configured using Raveon's Radio Manager software program. More Details...
