Chapter 2 Setup and Operation
2.1. Connections
Wiring harnesses have been provided to make the proper connections from the
IP250-BV to its power source and the laser diode to be driven. One harness has a
three-pin connector mate the other has a four-pin connector mate.
The wire harness made with the 3-pin connector should be connected to J1 of the
IP250-BV and the ±12 V power supply. Connect to the power supply as follows:
Power Supply
Connector Wire Color Designation
J1-1 Red +12 V
J1-2 Black Common
J1-3 Yellow -12 V
The wire harness made with the 4-pin connector should be connected to J2 of the
IP250-BV and the laser diode to be driven. Connect the laser diode as follows:
Laser Diode Connections
Connector Wire Color Designation
J2-1 Blue Laser Anode
J2-2 Black Laser Cathode Ground
J2-3 Black Monitor Photodiode Cathode
J2-4 Orange Monitor Photodiode Anode
Note: Either the monitor photodiode cathode or monitor photodiode anode MUST
be connected to ground somewhere in this system. Typically this is done at the
laser diode package itself on a common pin. To eliminate errors due to wire losses,
always return the photodiode ground connection on the wire provided. Do not use
a common wire for the photodiode and laser diode ground currents.
If the photodiode is completely isolated from the laser diode, install a wire jumper
into J3 of the IP250-BV to fix the ground connection to the photodiode cathode.
Refer to Figure 1 on Page 4 for the schematic diagram detailing the laser diode
connections.
This driver is limited to common-cathode (cathode grounded) laser diodes.
