-Both temp control loops can be toggled with a board-level switch located under the PID tuning switches. If you are experiencing problems with either of your temp loops, please toggle this switch off and then on again, as it's possible for the switch to get bumped into an intermittent position where it looks on, but is off. The most common symptom of this issue is that the faulty temp loop's front panel LED will turn red, but this does not always happen.

 **Laser Temp Output (8-pin connector)**
-An 8-pin Hirose connector (see <tabref TECconnectortable> for identity of connectors) carries the signals for the temperature control of the Laser module.  The wiring diagrams are shown in <tabref TEC_connector_pinout> below, where 1 (2) refer to stage 1 (2) temperature control, which stabilizes the Laser Housing (Laser Diode). Rth and Rth_Rtn are the two ends of a 10 kΩ [[http://www.analogtechnologies.com/ath10kr8.html|Analog Technologies ATH10KR8 Thermistor]].

 **Remote Interlock**
-The remote interlock can be used to disable the laser diode output via an interlock control.  When this input is shorted the laser diode output is ON.  When the input is open the diode output is OFF.  If not used, leave a shorting cap over this BNC. Once the interlock has been tripped, the laser will stay off until it is manually reset with the front panel switch.
