1. How do I switch from NMEA protocol to SiRF protocol for REB-12R and get the ID 2 message?
Ans:
1. Please refer the "Set Serial Port Command" on page 16 of REB-12R operational manual
(http://www.royaltek.com/eng/products/REB-12R.pdf) for switching from NMEA to SiRF protocol.
For example, if want to change to SiRF binary 9600, 8, N, 1. The command is:
$PSRF100,0,9600,8,1,0*0C
2. Please refer page 19 for "Calculating checksums for NMEA input".
3. After it switches to SiRF protocol, it will continuously output ID 2 message.
