3.2 Pin function
The functions of the pins are more described in the MSA document [1], except for the
pins 31, 33, 29, 35 and 37.
Table 3 . Non MSA pin functions.
Pin Pin# Description
Motor CLK 29
One of the following functions is possible to choose, see
section § 6.3.7.
1. Direction. Signal is high when the channelnumber
is increasing and low when it is decreasing.
2. Stepclock. Pulses (100ns duration) that are
syncronized with motorstepping. One period
corresponds to wavelength change of
≈
1pm .
LaserCurrent 31 Analog output proportional to laser diode current.
LaserPower 33 Analog output proportional to output power.
MeasGround 35 Ground for signals above (internally connected to GND)
+WaveClock 37
Analog output of normalized wavelocker signal.
Peak calibrated to 2V.
Differential pair with pin 39.
-WaveClock 39 Differential pair with pin 37
