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.

! verify ThaT The pLD is properLy orienTeD on The

boarD

, wiTh pin 1 aT The correcT LocaTion. refer To

Figure 5.

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.
