Range: 2-84, 86-223.

Analog/PT100 Settings

UC300 has two 4-20mA analog inputs, two 0-10V analog inputs and two PT100 inputs for analog device connection. After wirings, you can click “Fetch” to check if the value is correct.

PT100 Note

1. The temperature unit in the reporting package is fixed as °C.
2. Please modify the command IF condition threshold settings if you change the temperature unit.

Is continued for: the analog value should last for some time.

Set lockout time: after the lockout time, UC300 device will detect if analog value matches the condition. 0 means this IF condition will only be detected once.

Received a message| When UC300 device receive a specific message from server.
The Device Restarts| Reboot the device.
Received a D2D control command| This only works with UC300 LoRaWAN® version and the LoRa D2D feature is enabled. See details on chapter 4.5.

Milesight D2D Settings

Milesight D2D protocol is developed by Milesight and used for setting up transmission among Milesight devices without gateway. When the Milesight D2D setting is enabled, UC300 can work as a Milesight D2D controller to send control commands to other devices or work as a Milesight D2D agent to receive commands to trigger the DO or RS485 devices.

1. Go to “General -> Basic” page, enable Milesight D2D feature, define a unique D2D key which is the same as D2D controller or agent devices. (Default D2D Key: 5572404C696 E6B4C6F52613230313823)
2. Go to “LoRaWAN Settings -> Basic” to configure the RX2 datarate and RX2 frequency. When UC300 works as D2D controller, it will send commands as RX2 settings.
3. Go to “Command” page to set corresponding operations. When DI triggers, UC300 can work as D2D controller to send control command to control the D2D agent device. The command should be a 2-byte hexadecimal number.

When UC300 receives a D2D command, it can work as a D2D agent to trigger the DO or send Modbus command to RS485 terminal devices.

Note: When this feature is enabled and the command is triggered, the device will not send data to LoRaWAN® network server.
