MR-350 Water Proof GPS Receiver

Discontinued. No longer available.

External weatherproof mounting
SiRF Star III chipset
15' cable
Operating Temp -40C~ 85C

The MR-350 is a "mini" external GPS receiver, which utilizes a bulkhead (through-hole) mounting design for applications that require a more permanent weatherproof mounting solution. The built-in GPS receiver is self-contained with the latest "20" channel SiRF Star III high performance GPS chipset for accurate positioning and an active patch antenna.

The extended 15' data cable allows for easy routing to your laptop behind headliners and side panels and terminates to a custom PS/2 connector for interfacing with one of the available BR305 cable sets that can be purchased separately (USB/RS232/ PDA). NB: A BR305 cable set is REQUIRED for the MR-250 to function.

The MR-350 can be used in a wide variety of applications including being mounted on police and fire trucks, utility/commercial vehicles, boats and aircraft.
