Used for user encryption to avoid intercepting
airborne wireless data by similar modules.
The module will internally use these two bytes as
a calculation factor to transform and encrypt the
over-the-air wireless signal.

No.
Description
1
After setting the repeater mode by configuration, switch to the normal mode and the repeater starts working.
2
In the repeater mode, ADDH, ADDL are no longer used as the module address, but is correspondingly paired with the
NETID. If the data of one of the networks is received, it is forwarded to another network. The network ID of the repeater
itself is invalid.
3
In repeater mode, the repeater module cannot transmit and receive data, and cannot perform low-power operation.
4
The user enters the other mode from mode 3 (sleep mode) or during the reset process, the module resets the user
parameters during which the AUX outputs low level.
Repeater networking rules:
1. Forwarding rules, the repeater can forward data in both directions between two NETIDs.
2. In repeater mode, ADDH\ADDL is no longer used as the module address, and it is used as a NETID forwarding pairing flag.
