3 Quick Start
In order to allow an easy and quick start with the A2200-A module, this chapter pro-
vides a short overview on the important steps to be taken to receive NMEA mes-
sages with position information on a serial port (UART).
NOTE
UART operation. Please consider the pull-up resistor in your design or pull the
GPIO up right after reset by other means.
NOTE
push-pull output of a microprocessor. For a wake-up, including the initial one
after power on, a LOW-HIGH transmission is mandatory.
NOTE
collector / open drain output of a microprocessor!
3.1 Minimum Configuration
The following picture shows the minimum configuration for NMEA or binary outputs
received and commands sent via an RS232 interface based on the GPS module
A2200-A using a passive antenna.
