209		-RS485-BL can connect to either RS485 sensors or TTL sensor. User need to specify what type of sensor need to connect.
	209	+To use RS485-LN to read data from RS485 sensors, connect the RS485-LN A/B traces to the sensors. And user need to make sure RS485-LN use the match UART setting to access the sensors. The related commands for UART settings are:

211		-**~1. RS485-MODBUS mode:**
212		-
213		-AT+MOD=1 ~/~/ Support RS485-MODBUS type sensors. User can connect multiply RS485 , Modbus sensors to the A / B pins.
214		-
215		-**2. TTL mode:**
216		-
217		-AT+MOD=2 ~/~/ Support TTL Level sensors, User can connect one TTL Sensor to the TXD/RXD/GND pins.
218		-
219		-RS485-BL default UART settings is **9600, no parity, stop bit 1**. If the sensor has a different settings, user can change the RS485-BL setting to match.
