ILX Lightwave LDC-3700 Series User Manual

2.18.3 TEC Grounding Considerations
The TEC outputs of the LDC-3700 Series Laser Diode Controller are isolated from chassis ground;allowing either
output terminal to be grounded at the user's option. The thermistor's
(-) terminal and the TEC module's (-)
terminals are internally connected.
2.18.4 The LASER Connectors
At the lcft of center, u hen facing the back panel, you will find a 9-pin D-connector for the LD connections. The
p~nout diagram for this connector is shown in Figure
2.13.

2.18.5 Connecting to Your Laser
\E'l~cn connecting laser d~odes and other sensitive devices to the LDC-3700 Series Laser Diode Controller, we
recommend that the un~t be powered up and the LASER output be off (LASER MODE ON LED unlit). In this
co~~d~t~on.
;I lo11 ~rnpcdilnce shunt IS active across the output temnals. When disconnecting devices, it is only
ncccss:ln. to turn the
LASER Output off.
2.18.6 Li~scr Diode Connections and Shielding
IMPORTANT
Before connecting the laser diode to the LDC-3700 Series Laser Diode
Controller, be sure that the front panel (LASER MODE) ON switch
is in the
OFF position (ON LED unlit). Before tur'ning on the LASER output, be sure
thi~t the current limit has been correctly set.
The interlock pins
(1 and 2) on the LASER connector must be shorted in
order lo turn on the LASER output current.
