Chatper 9 Repeater networking mode

No.
User need to set the repeater function in configuration mode. After setting, switch module to the normal mode. Then
1
the repeater starts working.
In the repeater mode, ADDH/ADDL is no longer used as the module address, it is used as a NETID to pair and
2 forwarding. If the reperater receive the data from a network, then it will forward the data to the other network.
The network ID of the repeater itself is invalid in this case. (See below examples)
3 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. It is used as a NETID to pair and forwarding.
As shown in the figure：
① Primary repeater
"Node 1" NETID is 08.
"Node 2" NETID is 33.
ADDH\ADDL of Repeater 1 are 08，33 respectively.
So the data sent by node 1 (08) can be forwarded to node 2 (33)
Meanwhile,node 1 and node 2 have the same address, so the data transmitted by node 1 can be received by node 2.
② Secondary repeater
ADDH\ADDL of Repeater 2 are 33，05 respectively.
Therefore, Repeater 2 can forward the data of Repeater 1 to the network NETID: 05.
Thus node 3 and node 4 can receive the data from node . Node 4 outputs data normally, but no ourput from Node3 because Node 3 has
a different address from Node 1.
③ Two-way repeater
As shown in below：The data sent by Node 1 can be received by Node 2 and Node 4; The data sent by by Node 2 and Node 4 can also
be received by Node 1.
