Bluetooth data flows via the RX (L-band) cable. All data are transported by Bluetooth,
except for the RX signal and DC power.
The ACU Bluetooth connects with the preset PCU Bluetooth when the ACU is initializing.
The antenna is initializing when the connection of ACU Bluetooth and PCU Bluetooth is a
success.
Bluetooth was paired in a factory, but the user must re-pair the Bluetooth if the Bluetooth
module is changed. Refer to Figure 5-3 below.

NOTE: You can see the Bluetooth systems around the ACU when pairing the Bluetooth,
so you have to select the proper Bluetooth module. Our Bluetooth module's name is 'ESD'
and Bluetooth module's address is on the top side of the Bluetooth module.
