HIPPO

This document describes the format of the Host Independent Positioning Protocol
Object (HIPPO) protocol and messages implemented in the DR GPS module.
HIPPO is one of three communication modes of the DR GPS module, and is the
one present in normal usage. The serial port operates at 38400 baud, eight data
bits, no parity, one stop bit.
The other two modes are monitor mode, used for manufacture and low-level
diagnosis and control, and flash-loading mode, used for updating the firmware.
The receiver enters monitor mode through HIPPO command. The receiver will
also enter monitor mode if the firmware ROM checksum fails. The only way to
enter flash-loading mode is through the monitor mode. For detailed descriptions
of these two modes, see the document “DR GPS Flash Loading Requirements”,
Trimble PN 45058-XX-SP, Rev 1.20.
