3.2.2 Pulse width control instruction structure
1) Control system send the serial input instruction to fiber laser through Pin2, meanwhile send
the clock signal through Pin3. Instruction description will be transmit in binary system, and
first transmit the most significant bit.
2）Fiber laser instruction structure as below：
3）OxA5(A5h) is the data transmission activated byte of activated pulse width control interface,
OxA5 and all data byte is transmit to Pin2 serial input.
The data length is 4 bytes.
The first byte of instruction code is 0x01.
The fiber laser will be at high level status at least 10us in advance before changing “Enable”
at any connector, and will be at low level status at least 10us after all change finished.
All instruction design start with 0xA5 byte
4）Please setup low Pin19 before use the extend configuration
