PICO D is controlled and monitored by a set of analog and digital
control and status signals.
The user needs to implement the following electrical connections:
DC power +5, and
±
15 V, see paragraph 2.5.1
DC voltage, low noise, [ -10 V, 10 V] for setting the output wavelength, see
paragraph 2.5.4.1.
DC voltage, low noise, [ -1 V, 10 V] for setting the optical output power level,
see paragraph 2.5.4.2.
Setting appropriate digital control signals (0 V / 5 V logical levels), see para-
graph 2.5.3.1
Reading the status of appropriate digital status signals (0 V / 5 V logical levels),
paragraph see 2.5.3.3.
The electrical signals are accessible via the two connectors located on the rear side
of PICO D, see Figure 2–8. The top (6 pin) connector connects the DC power supply
to PICO D and the lower (40 pin) connector contains all other electrical control and
status signals, see Figure 2–8.
