FINE_TUNING Voltage
Desired Wavelength
Voltage Settings
Shortest wavelength corresponds to –10 V
-FINE_TUNING set to 0 V
+FINE_TUNING set to –10 V
Longest wavelength corresponds to +10 V
-FINE_TUNING set to 0 V
+FINE_TUNING set to +10 V
Note that a differential input stage is used, and thus, both +FINE_TUNING and –FINE_TUNING must
be connected.
Electrical Power and Signal Connectors
There are two connectors located on the left side of the INTUN TL-T. The top connector (6-pin) is the
power connector, and the 40-pin connector carries all digital and analog signals. The figure below shows
the pin configuration of the two connectors. The electrical power connector carries all the required DC
power lines.
The table below lists the signal interface’s pin configuration.
The type of connectors used is specified in the Power Connections section on page 29.

Pin Configuration for the electrical power connector. Note that an increased cable area is recommended
for the +5 V and GND (+5V) connections. The full pin configuration of the INTUN TL-T power and
signal connectors is shown in the following table.
The top (6-pin) connector
is the electrical power
connector, and the lower
(40-pin) connector is the
signal connector.
