PLD10000/PLD12500 LASER DIODE DRIVER
INSTALL THE PLD ON THE PLD10EV BOARD
Align the pins of the PLD with the plated holes on the
evaluation board, making sure all pins are aligned before
seating the PLD on the board.

Next, insert the two 4-40 x ¼” screws through the tabs on
the PLD and into the threaded inserts on the PCB; then
tighten. Finally, solder the PLD pins to the PLD10EV board.
It is essential to mechanically secure the PLD to the circuit
board with the 4-40 x ¼” screws. The electrical pins alone
do not provide sufficient mechanical strength to secure the
PLD to the circuit board.
CONFIGURE THE PLD10EV BOARD FOR
YOUR APPLICATION
If you are using the PLD10EV evaluation board to familiarize
yourself with operating the PLD10000 or PLD12500, follow
these instructions to configure the jumpers on the evaluation
board. Refer to Figure 5 .
• Laser Type-Select Jumper . Remove this jumper for
Type A/B laser operation. Install the jumper to tie pin 3
to pin 23 for Type C laser operation. The factory default
configuration is with the jumper removed.
• LD Power Supply Jumper. To operate the PLD and
laser from a single 5 VDC power supply, install this
jumper. If you are operating a high-compliance laser
with a separate power supply, remove the jumper. The
jumper must be removed when using the PLD12500.
The factory default configuration is with the jumper
installed.

WIRE THE PLD LASER DRIVER
Refer to Table 3 for wiring instructions specific to your
configuration. For setup and configuration use a test load.
The same wiring instructions apply whether the PLD is
used on the PLD10EV board or installed on a custom circuit
board.
