Manual of Two-Way Radio System www.FrSky-rc.com P2of9
e) Quick response.
f) Very smooth servo movement.
g) Alarm on events of receiver (low battery voltages, poor reception, etc.)
h) Error-free link, by using 48bits CRC algorithm.
i) Low power consumption.
j) True two-antenna diversity.
k) Firmware upgradable.
4. Function of Two Way communication
a) Two way communication between receiver and transmitter
b) Receiver is able to accept 2 analog inputs, which can be used to monitor battery
voltage, temperature sensor, etc., and transfer them to transmitter. Users can set the
Alarm Level of these analog voltages, when exceed or below these levers, sound alarm
is issued.
c) Receiver is able to accept serial data streams from simple 3-wire RS232 port, such
information as GPS, altitude, and user developed data can be transferred to Tx without
error, and sent at the RS232 port on the Tx.
