DESCRIPTION
For TYPE C laser diodes only. See page 12.
For TYPE C laser diodes only. See page 12.
Enable Output Current = +3 to +5 V
Disable Output Current = Ground or Floating
LIMIT status. LIMIT = Ground Normal Operation = High Impedance
If Limit is detected, laser diode current will turn off, Limit I LED will light.
Toggle LD ENABLE to restart laser diode current.
Current Limit setpoint monitor. Impedance = 1 k
Ω
Output 0 to 2.5 V
NOTE: Current limit needs to be set 0.2 V above desired limit level.
Measurement ground. Low current return used only with pins 5, 7, 8, & 9.
Shorted to pin 11 internally.
Laser Diode current monitor. Impedance is 1 k
Ω
Output 0 to 2.5 V
Power monitor (PD current monitor). Impedance = 1 k
Ω
Output 0 to 2.5 V
Remote setpoint or modulation input. Input impedance = 1 M
Ω
Input 0 to 5 V
Connect Pin 9 to Pin 6 when not in use.
Supply voltage to control electronics. Min +4.5 V Max +5.5 V
Power supply ground. Used with pin 10 for high current return.
Laser Diode Anode and laser diode supply connection.
RecomLD Supply for single laser is +5 V. M30 V.
CAUTION: Too high a voltage may thermally damage the PLD.
Laser Diode Cathode
For Type A or B laser diodes, Photodiode Anode.
See page 12 for use with Type C laser diodes.
For TYPE C laser diodes only. See page 12.

The following laser diode / photodiode configurations are
currently manufactured - Type A, Type B, and Type C. Setup
and operation vary according to your type of laser diode.
Please identify which laser diode you will be using with
the PLD and follow the appropriate operating instruc-
tions.
Operating instructions for lasers of Type A or B are detailed
on page 8.
Operating instructions for Type C Lasers are detailed on
page 12.
