	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 in the **process sensor returns area**.
79	79
	80	+**Example:**
80	80
	82	+User configure below commands :
81	81
	84	+* Poll Command 1: 04 03 00 00 00 02 C4 52
	85	+* Poll Command 3: 08 03 00 00 00 02 C4 92
	86	+* Poll Command 5: 11 03 00 00 00 02 C6 9B
	87	+
	88	+Then Click "Test RS485 Commands". End Node will then send these three commands to RS485 sensors one by one and waiting for returns.
	89	+
	90	+Their returnes will be shown in "RS485 Return Data" Area, such as below:
	91	+
	92	+[[image:image-20230930193108-1.png]]
	93	+
	94	+Use can choose to get "Discrete Data Bytes" or "Bytes Blocks":
	95	+
	96	+[[image:image-20230930193257-2.png]] Select the 1st ~~ 3rd bytes from the return.
	97	+
	98	+[[image:image-20230930193357-3.png]] Select the 3rd, 6th, 9th bytes from the return.
	99	+
	100	+[[image:image-20230930193456-4.png]] After select the byte fetch method. User can see preview the result. This photo shows to fetch the Block 1~~3 from the first return.

	108	+**AT+CMDDL**: This specify the delay for RS485 End Node to wait for the RS485 sensors return. If RS485 sensors doesn't reply in this time. End Node will consider there is no reply.
	109	+
	110	+**Generate AT Instructions**: After All testing goes fine with Poll Command & Return Process. User can press this button to generate the AT Commands which is for the Ene Node.

	114	+
	115	+This window show the commands to be flash into the RS485 end node.
	116	+
	117	+* **Import Commands**: Import commands from txt.
	118	+* **Save Commands**: Save commands to a txt.
	119	+* **Write**: Write Commands to End Node
