Anode lead and the red LD Anode Sense lead are both wired to the
laser ground pin (typically pin 3). Similarly, the red PD Anode lead
is wired to the photodiode Anode pin (typically pin 4), while the
blue PD Cathode lead is wired to laser ground (again, pin 3).
When using these mounts, it is necessary to re-wire the flying-lead
end of the cable each time the grounding configuration of the mount
is changed.

TEC cables
Two styles of cable are also available to connect the LDC500 series
controller to a thermoelectric cooler—a flying-lead cable and a double
terminated cable. Both styles are built with the male DB-15 connector
to mate with the TEC output of the controller. All SRS TEC cables
are constructed for high flexibility and high current capacity, and
optimized for use with the LDC500 Series Laser Diode Controllers.
The terminated version of the cable (see Figure 6.3) is available in
two lengths (6 ft and 12 ft).

This cable can be used with customer-built laser mounts with a
male DB-9 connector. Alternatively, these can be used with some
LDC500 Series Laser Diode Controllers
