Example: The network disconnection recovery time is set to: 30 seconds. After the sender and receiver are
disconnected, the product will continue to search for connections. If the connection between the sender and the
receiver is still disconnected after 30 seconds, the product network indicator "NET" light is off, and the receiver
returns to the default output parameter of 0mA.
(3) Refresh interval: Refers to the time interval for synchronous refresh of the data of the sender and the
receiver. Note: The refresh interval is related to the parameters related to the communication mode, see Table
4-3 below.

(2) I/O configuration parameter writing:
1. Example: Write 4~20mA file, 60s disconnection recovery time, 2s refresh interval.
2. Steps (as shown in Figure 4-12): Select the correct COM port number and correct (default) parameters →
click "Open Serial Port" (if the parameters have been changed and forgotten, they can be restored to factory settings)
→ "Search/Read Device" → "I/O configuration" → pull down to select " 4 ～ 20mA " → input network
disconnection recovery time 60s (0s, 30～57600s) → pull down to select the desired refresh interval time 2s →
click "write" in "3.I/O configuration" Enter " → the log column prompts success → According to Table 4-2,
configure the LoRa wireless airspeed to 2.4Kbps → click "Write" in "2.LoRa Configuration" → log column
prompts success → click "Save" → read next Check whether the verification is successful → click "Restart"
→ Repeat "
