UC300 supports 4 digital inputs. Each input can work as either digital input mode to detect high/low level or pulse counter to record counting values. When working as digital input, UC300 will upload the data according to reporting interval or when status changes.

• Interface Name: DI_1, DI_2, etc.
• Enable: Check to enable the input.
• Interface Type: Select 'Digital Input' or 'Counter'.
• Status: Displays current input status. A 'Fetch' button is available to get the current status.
• Digital Filter: Recommended to enable when pulse period is greater than 250 us.
• Counter Values: Displays the current count. 'Refresh' to get latest values, 'Start' to start/stop counting, 'Clear' to reset to 0.

Note: The counting value will lose if UC300 loses the power.

4.3.3 Digital Output Settings

UC300 supports 2 digital outputs to control the devices.

• Interface Name: DO_1, DO_2.
• Enable: Enable the digital output to control the device and upload changed status.

• Status: Displays current output status. 'Fetch' to get status, 'Switch' to change status.

4.3.4 RS485 Settings

UC300 has one RS485 port for Modbus RTU device connection.

1. Connect RS485 device to RS485 port.
2. Go to "General -> RS485" to enable RS485 and configure serial port settings. Serial port settings should be the same as the RS485 terminal devices.

Configuration parameters include:

• Enable: Allow the device to collect RS485 data and upload the data.
• Stop Bit: 1 bit/2 bit are available.
• Data Bit: 8 bit is available.
• Parity: None, Odd and Even are available.
• Baud Rate: 1200/2400/4800/9600/19200/38400/57600/115200 are available.
• Execution Interval (ms): The execution interval between each Modbus channel command.
• Max Resp Time (ms): The maximum response time that the UC300 waits for the reply to the command. If it does not get a response after the max response time, it is determined that the command has timed out.
• Max Retry Time (ms): Set the maximum retry times after device fails to read data from RS485 terminal devices.
• Modbus RS485 bridge LoRaWAN: If this mode is enabled, the device will transmit Modbus RTU commands from network server to RS485 terminal devices transparently and send Modbus reply originally back to the network server.
• Port: Select from 2-84, 86-223.

3. Click to add Modbus channels, then save configurations. The Channel Settings interface allows configuring Channel ID, Name, Slave ID, Address, Quantity, Type, Byte Order, Sign, and Value. A 'Fetch' button is available to test data reading.

Note: Do not click “Fetch” frequently since response time to reply is different for every terminal device.

4.3.5 RS232 Settings

UC300 has one RS232 interface for transparent communication. It usually uses different tunnels from other data interfaces to communicate with the server.

Configuration parameters include:

• Enable: Enable RS232 communication.
• Baud Rate: 1200/2400/4800/9600/19200/38400/57600/115200 are available.
• Stop Bit: 1 bit/2 bit are available.
• Data Bit: 8 bit is available.
• Parity: None, Odd and Even are available.
• Packet Length (byte): When the device receives RS232 data up to this length, it will fragment it as a single packet and send to network server.
• Serial Frame Interval (ms): The interval that the device sends out real serial data stored in the buffer area to the public network. The range is 10-65535 milliseconds. Data will be sent out when real serial data size reaches the preset packet size, even though it's within the serial frame interval.
• Port: Send or receive RS232 data from this port; this port should be different from the Application port. Range: 2-84, 86-223.

4.3.6 Analog/PT100 Settings

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

• 4-20mA_1: Configure Osh (Offset Scale High), Osl (Offset Scale Low), Unit (mA), and Status.
• 0-10V_1: Configure Osh, Osl, Unit (V), and Status.
• PT100_1: Configure Unit (°C) and Status.

PT100 Note:

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

4.4 IF-THEN Command

UC300 supports configuring locally IF-THEN commands to perform actions automatically, even without network connection. One device can be added with up to 16 commands.

1. Go to "Command" page, click “Edit” to add commands.

IF Condition Types:

• Digital Input: Based on DI status (e.g., DI 2 or DI 3 goes active, rising edge-triggered). Can specify if it's 'continued for' a duration. 'Set lockout time' prevents rapid re-triggering.
• Counter: When pulse counter reaches a specific value or any threshold.
• Channel/4-20mA/0-10V/PT100: Based on analog value thresholds, can be 'continued for' a duration. 'Set lockout time' applies.
• Received a message: Triggered when UC300 receives a specific message from the server.
• The Device Restarts: Triggered upon device reboot.
• Received a D2D control command: Triggered by a D2D command. This works with UC300 LoRaWAN® version and D2D feature enabled.

THEN Action Types:

• Send a custom message: Send a custom message to the server.
• Output Trigger: Control Digital Outputs (DO) to be normally open/closed or change status. Can set 'Delay Time' and 'Duration'.
• Restart the Device: Reboot the device.
• Send a D2D control command: Send a D2D control command to another device. Works with D2D feature enabled.
• Send a Modbus command via RS485 interface: Send a Modbus command to RS485 terminal devices. Works with D2D feature enabled.

Example configurations show how to trigger actions based on Digital Input status or received D2D commands.

4.5 Milesight D2D Settings

Milesight D2D protocol is developed by Milesight for transmission among Milesight devices without a gateway. When D2D is enabled, UC300 can act as a D2D controller to send commands or as a D2D agent to receive commands.

1. Go to "General -> Basic" page, enable Milesight D2D feature, and define a unique D2D key (same as controller/agent devices).
2. Go to "LoRaWAN Settings -> Basic" to configure RX2 datarate and RX2 frequency, which will be used for D2D commands when UC300 acts as a D2D controller.
3. Go to "Command" page to set corresponding operations. When DI triggers, UC300 can send control commands to a D2D agent device. The command should be a 2-byte hexadecimal number.

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