1 The letter in the part number identifies the revision of the module. For example, part
number 185715A-02 identifies a revision A cFP-PWM-520. The part number is
printed on a label on the module. On the FP-PWM-520, the label is on the bottom of
the module. On the cFP-PWM-520, the label is on the back of the module.
