Method
Process
4.
If pairing successfully within 60s, remote control COMM indicator
extinguishes after illuminating green 2s, receiver LoRa and RS485 indicators
extinguish, POWER indicator keeps green for a long time. Otherwise, COMM
indicator keeps red for a long time when the pairing fails.
Method 2:
Receiver waits for
remote
control
pairing.
1.
Turn the remote control and receiver to the same channel. (see the
communication channel configuration, default channel is 515MHz.)
2.
Turn on the receiver power, POWER indicator keeps on. Insert a slender
needle less than 3.5mm in diameter into the PAIR hole vertically, then long
press PAIR key 6s, LoRa, RS485 and POWER indicator flash green. Press
PAIR key again during LoRa pairing can cancel pair.
3.
Turn on the remote control power, its power indicator keeps on. Long
press F2 key 6s.
4.
If pairing successfully within 60s, remote control COMM indicator
extinguishes after illuminating green 2s, receiver LoRa and RS485 indicators
extinguish, POWER indicator keeps green for a long time. Otherwise, COMM
indicator keeps red for a long time when the pairing fails.

RS485 INTERFACE
Receiver connects to engine controller via RS485 interface, 120Ω terminal matching resistor is
recommended to use (when RS485 A(+) and TR terminal is short connected), RS485 communication
line must use twisted shielded pair line.
