PIN DESCRIPTION

Pin	Symbol	Name	Description
1,17,20	VeeT	Transmitter signal ground	These pins should be connected to signal ground on the host board.
2	TX fault	Transmitter fault out(OC)	Logic“1 ”output = laser fault (laser off before t_fault) Logic“0”output = normal operation This pin is open collector compatible, and should be pulled up to Host Vcc with a 10k Ω resistor.
3	TX disable	Transmitter disable in(LVTTL)	Logic“1 ”input (or no connection) = Laser off Logic“0”input = laser on This pin is internally pulled up to Vc cT with a 10 kΩ resistor.
4	SDA	Module definition identifiers	Serial ID with S FF 8472 diagnostics module Definition pins should be pulled up to Host Vcc with 10kΩ resistors.
5	SCL
