8. Relay networking mode
No.
Relay mode description
1
After setting the relay mode through configuration, switch to the general mode and the relay starts to work.
2
In the relay mode, ADDH and ADDL are no longer used as module addresses, but are forwarded to the
NETID respectively. If one network is received, it is forwarded to the other network. The repeater's own
network ID is invalid.
3
In the relay mode, the serial port of the relay module cannot send and receive data and cannot perform
low-power operation.
4
When the user enters other modes from mode 3 (sleep mode) or during the reset process, the module will
reset the user parameters, during which AUX outputs low level.
Relay network rules:
1. Forwarding rules. The relay can forward data in both directions between two NETIDs.
2. In relay mode, ADDH \ ADDL is no longer used as the module address, and is forwarded and matched as NETID.
3. In the relay mode, please do not send more than the set single packet sub-byte
As shown in the figure:
①
Primary relay
"Node 1" has a NETID of 08.
"Node 2" has a NETID of 33.
ADDH \ ADDL of relay 1 is 08 and 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 of relay 2 is 33,05, respectively.
So relay 2 can forward the data of relay 1 to the network NETID: 05.
Thus node 3 and node 4 can receive node 1 data. Node 4 normally outputs data. Node 3 and Node 1 have different
addresses, so no data is output.
③
Two-way relay
As shown in the figure, the data sent by node 1 can be received by nodes 2 and 4, and the data sent by node 2 and 4
can also be received by node 1.
