External interface standard six wires

1、power line:Red is positive,Black is ground electrode ground electrode and serial port line is shared , input voltage +±5% deviation ,over high can lead to burning device。

2、Communication is half duplex mode, green line is TX of UART .Serial data output format:ByteH, ByteL, $FF three bytes For example 305m=01H,31H, FFH

3、When data output is error:88H, FFH and FFH.

4、Blue line is control line, Ground work, disconnect or high level ( +5V) stop

5、Yellow is positive、blue is negative。

Two cores group:

Red dot indication: power supply two lines : green line: +3V-5V, grey line: ground line

Laser class I class

Humidity range:0% -100%
