GPS configuration
The three jumper blocks illustrated below let you configure the mode of operation of
your GPS receiver module. The topmost jumper is the GPS receiver hardware reset,
the ROM jumper configures whether settings from the EEPPROM are used during
startup or not, NMEA jumper sets the protocol mode of the receiver. Table 2-3
describes in detail the operation of these jumpers. Note that if you change the jumper
settings for ROM or NMEA you should perform a reset of the receiver by closing the
contacts of the RST-jumper for the changes to take effect.
(Factory setting: ROM disabled, NMEA)

RESULT
NMEA message format, communication at
4800bps, NO parity, 8 data, 1 stop. The
receiver operates from default initialization
values stored in ROM and will output
default NMEA message set from ROM
NMEA message format, communication at
4800bps, NO parity, 8 data, 1 stop. The
receiver selects the default NMEA output
message set and uses initialization values
from the data stored in SRAM or EEPROM
Binary message format, communication at
9600bps, NO parity, 8 data, 1 stop. The
receiver operates from default initialization
values stored in ROM
Data stored in SRAM or EEPROM
determines message format, host port
communication settings, and default mes-
