7. Relay Network Mode Use
No. Relay mode description
1
After setting the relay mode through the configuration mode, switch to the normal mode and the relay starts
to work.
2
In relay mode, ADDH and ADDL are no longer used as radio addresses, but correspond to NETID
forwarding and pairing respectively. If one network is received, it will be forwarded to another network.
The network ID of the repeater itself is invalid.
3 In the relay mode, the relay station cannot send and receive data, and cannot perform low-power operation.
4
When the user enters other modes from mode 3 (sleep mode) or is in the reset process, the radio will reset
the user parameters, during which AUX outputs low level.
Description of relay networking rules:
1
、
Forwarding rules, the relay can forward data in both directions between two NETIDs.
2
、
In the relay mode, ADDH\ADDL is no longer used as a DTU address, but as a NETID forwarding pairing.
As shown:
①
Primary relay
"Node 1" NETID is 08.
"Node 2" NETID is 33.
The ADDH\ADDL of relay 1 are 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.
