5.1 ON and RESET Push-Button
The EVA2200-A has two push-buttons:
•
ON (ON / OFF functionality)
•
nRST (RESET functionality)
After power on pushing the “ON” button will start the A2200-A module. This is ab-
solutely necessary to get t
he module going. The “ON” button must be used as well in
other cases, e.g. in order to request a position when in SiRFaware
TM
state or to go to
hibernate mode and wake up again.
The
“nRST” button is used to get a full reset of the GPS module. All parameters are
stored in non-volatile memory. After pushing this button the module starts again from
the beginning.
5.2 Antenna Connector
The A2200-A supports one antenna input. Both active and passive GPS antennas
can be connected to GPS input as below. Only active GPS antenna was equipped
inside evaluation kit.
