4 External Connections ITC8xxxDS15
The ITC8000DS15 Combined Controllers come with a single output connector that accommodates
the external connections for both the laser current and the temperature controllers. The functionality
is the same, except for the TEC controller status LED. Therefore, in this section are stated the
external connections of the common 15 pin output connector with respect to the different pin
assignment.
