Holux GR-213USB User manual

GR-213USB GPS Receiver
 Features:
 SiRFstarIII chipset with embedded ARM7TDMI CPU available for customi ed applications
in firmware
 High performance receiver tracks up to 20 satellites while providing first fast fix and low
power consumption.
 Compact design ideal for applications with minimal space.
 A rechargeable battery sustains internal clock and memory. The battery is recharged during
normal operation.
 Users can adjust power-saving percentage (20%~80%), which achieves the best power
efficiency.
 User initiali ation is not required.
 LED display status: The LED provides users visible positioning status. LED “ON” when
power connected and “BLINKING” when GR-213U got positioned.
 Water proof design for industry standard.
