Function
SCB
VCC
VCC3
Safety Circuit Bypass. Connect to GND or leave open for normal operation.
Connect to VCC to allow the bias and modulation outputs to operate even if
the safety circuitry indicates a fault.
SCB
24 kΩ
48 kΩ

DISDLY
VCC
(M02061-12
only)
DISDLY
190 Ω
Disable delay control. Connect to ground for normal operation. In burst mode
operation add a capacitor from this pin to ground to set the maximum disable
time. Disable times greater than this maximum will engage the âslow-startâ
circuitry.

MODMON
Modulation Current Monitor. Connect directly through a resistor to GND
VCC
VCC3
(MONPOL high) or to VCC3 (MONPOL low). The current through this pin is
approximately 1/100th of the MODULATION current to the laser.
This pin may be left open if the feature is not needed and the M02061 current
consumption will be reduced by 0.5mA typically.
