3 Quick Start
In order to allow an easy and quick start with the A2035-H module, this chapter
provides a short overview on the important steps to be taken to receive NMEA
messages with position information on a serial port (UART).
NOTE 1
: The A2035-H needs an external pull-up resistor to be configured for
UART operation. Please consider the pull-up resistor in your design or pull the
GPIO up right after reset by other means.
NOTE 2
: The ON_OFF input of the A2035-H needs to be connected to output of
a microprocessor. For a wake-up, including the initial one after power on, a
LOW-HIGH transmission is mandatory.
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
A2035-H.
Figure 5: Minimum configuration A2035-H
NOTE
: It is recommended to supply Vcc continuously! Use SiRFaware
TM
or
other low power modes to reduce power consumption of the module while no
position information is required.
