CONFIGURING THE DEMO BOARD
STEP 3: INSTALL THE LASER DIODE CONFIGURATION BOARD
CAUTION: If the WLD3393 is confi gured incorrectly for the type of laser diode you are using,
damage can result to your laser diode and/or the WLD3393.
Refer to Figure 5 to determine the
type of laser diode being used. To confi gure the WLD3393 for your laser diode type, connect the
confi guration board to the bottom of the WLD3393 so that the arrow on the protruding edge of the
confi guration board points to either A/B or C. Refer to Figure 6 for example installation.
