 The connections to the TECs and thermistors are made to an 8-pin Hirose connector (see <tabref TECconnectortable> for identity of connectors).  The pin definitions are:

 NOTE:  Earlier models use a push-pull connector for the 8-pin connector to the DBR module.  To remove take care to apply opposition forces with the thumb and forefinger knuckles against the housing.  Excessive force could displace the output beam and require realignment.

 Never connect or disconnect the D2-100 Laser to a laser controller that is energized.  Always power down the laser controller completely before making connections to this laser.

-=====Aligning the DBR Laser Module=====
-The module should not need adjustments, but if necessary the following procedure can be used to fine tune the beam positioning.
-  - Loosen the three locking screws on the back of the DBR module ½ turn past the crack point.
-  - With a 0.050" Allen driver, adjust the vertical adjustment setscrew on the top of the DBR housing to level the beam.
-  - Adjust the horizontal adjustment 4-40 set screw on the left side of the DBR housing (See <imgref DBR_lock_screws>).
-  - Alternatively, use the spectroscopy module as a beam target.  Place the spectroscopy module as far down the table as possible, bolt it down, and center the beam to the input hole.
-  - Gently retighten the three locking screws.
