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.
