5.5 General Comments
The following comments should be considered for a design with and use of the
module:
•
Standard configuration of serial port (no DR software):
Serial 0 (NMEA) 4800 baud, 8 data bits, no parity, 1 stop bit, no flow control
Serial 2 (DGPS) 4800 baud, 8 data bits, no parity, 1 stop bit, no flow control
•
Standard configuration of serial port (with DR software):
Serial 0 (NMEA) 57600 baud, 8 data bits, no parity, 1 stop bit, no flow control
Serial 2 (DGPS) 4800 baud, 8 data bits, no parity, 1 stop bit, no flow control
•
Antenna (Antenna connected to Antenna Pin – A1029-A only)
Use ground pins (pin 21, pin 23) close to the antenna input for RF ground.
•
Gain Select
Default setting is “open” (identical to logical low), which results in a high gain
(14dB). This setting is recommended.
•
nRST
Do not pull low when in low power mode (ENABLE = LOW)
