Operating elements at the rear panel
The rear panel of the laser diode controller LDC340 contains the mains connector
with fuse, the output jack (9pin D-SUB), the external monitor diode input (BNC), the
temperature window protection input (BNC) as well as the preset DIP switch bank
and the PD gain control potentiometer.
If the LDC340 is equipped with the IEEE488.2 interface ( LDC340-IEEE) there is an
additional DIP switch bank to set the IEEE 488 device address. You will also find the
24pin IEEE488 jack.
