9. Repeater networking mode
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.
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.
