(Connector Part Number: 51004-1000)
Pin
Number
Pin Label Function
1
VDC
Power supply, 5 - 12 V. Standard operation can use 5V. For units with > 1W output power,
at least 9V is required. Pins 1 & 6 connected.
2
SET
ENABLE
Enable external laser power control through pin 8 (LD SET):
High = Disable
Low = Enable
3
TX/SCL
I2C: SCL standard (RS232: TX, by request)
4
RX/SDA
I2C: SDA standard (RS232: RX, by request)
5
GND
Ground. Pins 5 & 10 connected.
6
VDC
Power supply, 5 - 12 V. Standard operation can use 5V. For units with > 1W output power,
at least 9V is required. Pins 1 & 6 connected.
7
ENABLE
Laser enable (Modulation):
High = Enable
Low = Disable
8
LD SET
Laser power setpoint
Apply a voltage bias in 1:1 ratio to drive current - be aware that this approach may cause
laser mode hopping behavior in single-mode lasers. Ground Pin 2 to enable this option.
9
PD
Photo diode voltage output (0.0 - 3.3 V)
10
GND
Ground. Pins 5 & 10 connected.
