In relay mode, the relay module cannot send and receive data, and cannot operate with low power consumption.

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.

Description of trunk networking 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 a module address, but as a NETID forwarding pair.。

As shown in the picture:

1. Level 1 relay

"Node 1" has a NETID of 08.

"Node 2" has a NETID of 33.

The ADDH\ADDL of trunk 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.

2. Secondary relay

The ADDH\ADDL of relay 2 are 33 and 05 respectively.

So relay 2 can forward the data of relay 1 to network NETID:05.

Thus node 3 and node 4 can receive node 1 data. Node 4 outputs data normally, and node 3 has a different address

from node 1, so no data is output.

3. two-way relay

Configuration as shown 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

also be received by node
