8: Use of the relay network mode
After setting the relay mode through the configuration mode, switch to the general mode, and the relay starts working.
In relay mode, ADDH, ADDL is no longer the module address, but corresponding to NETID forwarding pairing, if one of the
networks is received, it is forwarded to another network;
The repeater's own network ID is invalid.
In relay mode, the relay module cannot send and receive data and cannot perform low-power operation.
The user enters another mode from mode 3 (sleep mode), or during the reset process, the module resets the user parameters,
during which the AUX outputs a low level.
Description of the relay networking rules:
1、 Forward rules, the relay can forward data between two NETIDs.
2、In relay mode, ADDH \ ADDL is no longer used as a module address and serves as a NETID forwarding pairing.
as shown in the figure:
① Level 1 Relay
"Node 1" NETID is 08.
"Node 2" NETID is 33.
The ADDH \ ADDL for relay 1 was 08,33, respectively.
So the signal sent by node 1 (08) can be forwarded to node 2 (33)
At the same time, node 1 and node 2 have the same address, so the data sent by node 1 can be received by node 2.
② Secondary Relay
The ADDH \ ADDL for relay 2 was 33,05, respectively.
So the relay 2 can forward the data of the relay 1 to the network NETID: 05.
Thus, the nodes 3 and the node 4 can receive the node 1 data. Node 4 normally outputs data, and node 3 has different
addresses from node 1, so it does not output data.
③ bi-directional relay
As configured, data nodes 2 and 4 sent by nodes 1 may be received, and data sent by nodes 2 and 4 can also be received
by nodes 1.
