Ⅸ Relay Networking Mode Usage
serial
number
After setting the relay mode by configuration, switch to the general mode and the relay starts
1
In repeater mode ADDH,ADDL are no longer used as module address, but correspond to NETID to forward
2 pairing respectively, and if one of the networks is received, it will be forwarded to the other
3 In relay mode, the relay module serial port cannot send and receive data for low-power operation.
Trunking Networking Rules Description:
1、forwarding rules, relay can forward data in both directions between two NETIDs.
2、In relay mode, ADDH\ADDL is no longer used as the module address, as NETID forwarding pair.
3、In relay mode, the data sent should not exceed the set single packet packetization byte
As pictured:
first-rate relay
1
"Node 1" NETID is 08.
"Node 2" NETID is 33.
The ADDH\ADDL of Relay 1 is 08, 33 respectively.
So the signal sent by node 1 (08) can be forwarded to node 2 (33)
Also node 1 and node 2 have the same address, so the data sent by node 1 can be received by node 2.
Secondary Relay
2
The ADDH\ADDL of Relay 2 is 33, 05 respectively.
So relay 2 can forward relay 1 data to network NETID: 05.
Thus node 3 and node 4 can receive node 1 data. Node 4 outputs data normally, node 3 has a different address
from node 1, so it does not output data.
bidirectional relay
3
As configured in the figure: the data sent by node 1 can be received by nodes 2 and 4, and the data sent by
nodes 2 and 4 can be received by node 1.
