	29	+
	30	+== Overview ==
	31	+
	32	+Below is the block diagram of the RS485 Tool:

	35	+
	36	+
	37	+== 3.1 General Configure: ==
	38	+
	39	+* **Port**: COM port in PC to connect to RS485 End Node.
	40	+* **Node Baud Rate**: The Baud Rate for RS485 End Node.
	41	+* **5VT**: 5v Power_On_Duration for external RS485 Sensors. Unit: ms.
	42	+* **Connect End Node**: Connect to RS485 End Node.
	43	+* **Disconnect End Node**: Disconnect RS485 End Node.
	44	+
	45	+* **Sensor Baud Rate**: Baud Rate of RS485 Sensors.
	46	+* **Sensor Data Bit**: Data Bit of RS485 Sensors
	47	+* **Sensor Check Bit**: Check Bit of RS485 Sensors.
	48	+* **Sensor Stop Bit**: Stop Bit of RS485 Sensors
	49	+* **Configure Devices**: Send General Configure Command to End Node.
	50	+
	51	+== 3.2 Console Window: ==
	52	+
	53	+After **Connect End Node**. The Console Window will shows all the output from RS485 End Node.
	54	+
	55	+User can also Send AT Commands to RS485 End Node in this window.
	56	+

	58	+
	59	+
	60	+== 3.3 RS485 Commands to Sensor ==
	61	+
	62	+This area is used to configure what RS485 Commands the End Node should send to the RS485 sensors to get the sensor value.
	63	+
	64	+* There are totally 15 commands max.
	65	+* Each command should be set according to the sensor manual.
	66	+* It is HEX format and no need 0x. Each byte should have a space in between (will be fix in next version so no need space).
	67	+* User should calculate the CRC if needed
	68	+
	69	+**Example**:
	70	+
	71	+* Sensor Command: FE 03 00 00 00 03 11 C4  (11 C4 is CRC). User need to input: FE 03 00 00 00 03 11 C4 as poll command.
	72	+
	73	+**Test RS485 Commands**: After configure poll commands. Click this button then the tool will generate related AT+COMMANDS and send to the End node to test and get return.
	74	+
	75	+
	76	+== 3.4 Process Sensor Returns ==
	77	+
	78	+RS485 sensors will return a string, to make it more efficient to process via LoRaWAN packets, we can fetch the valid chars from the returns by this area.
	79	+

	83	+
	84	+~1. Add Payload Structure Window
	85	+
	86	+2. Modify Chars to looks nicer
	87	+
	88	+3. Each COmmand can have seperate return process command.
