GPS module interface
The GPS pin interface consist of: GND, +3V , RX0. The characteristics are:
Baud rate: 38400
Data bits: 8
Stop Bits: 1
Parity: None
Interface Features: TTL level
Connect the above to the GPS Receiver. The GPS data protocol is a standard NEMA0183 and the statement
must be $ GPRMC, $ GPGGA.
Attention :
DOS fixed-wing aircraft firmware version V1.21 and above is not support connect the Hornet-OSD.
Please do not connect the Hornet-OSD to DOS GPS port
.
Data Radio interface
The UART pin interfaces consist of: GND, power 5V , TX1, RX1. The characteristics are as follow:
Baud Rate: 19200
Data bits: 8
Stop Bits: 1
Parity: None
Interface Features: TTL level
The pin interfaces connects to the Data Radio, PC computer serial port or OSD module. You can set DOS
control parameters through this interface. The port is also used to upgrade DOS firmware. Please read the
procedure for the firmware upgrade.
Attention :
