Antennas Connection

Each antenna is connected to some JNSGyro-4T board. The boards are
connected to each other through the serial ports as shown in Figure 3-4.
The first board is referred to as Master. The other three boards (2nd, 3rd,
and 4th) are called Slaves.
Master sends raw data to Slaves. They process the data and send results
back to Master. It processes the results and calculates the attitude. To
provide data exchange between the boards, they are interconnected as
shown in Figure 3-4.
The modem for receiving the differential corrections from the remote base
can be connected to any port of any Slave, for example, to the port A of
Slave2 as shown in the figure. To instruct Slave2 to transmit the differential
corrections to Master, the following GRIL commands must be sent to
Slave2:
set,dev/ser/a/imode,echo
set,dev/ser/a/ewrap,on
set,dev/ser/a/echo,/dev/ser/b
