Remote Modulation Control Configuration
8.5 SELECTIVE PULL-UP/PULL-DOWN OF CONTROL SIGNALS
By default, the main laser control signals are actively pulled down to ground through 20K resistors as
shown in the following figure. If necessary, jumper selectable pull-up resistors may be applied to
permit setting these signals to a high state during power-up cycles. The use of these jumpers is laser
specific. Please consult your laser manual for best practices in this regard.
