DB-9 I/O connections

The DB-9 I/O connector provides a +5 VDC auxiliary output (DC Out), a PWM input, an enable input, and
four status outputs. The user inputs, Laser Enable and PWM Positive/PWM Negative, enable lasing and
provide output power control. User outputs indicate vi30/40 ready, lase, overtempt, and input voltage
status. The OEM vi30/40's PWM inputs are optoisolated; however, all other inputs and outputs operate
using standard 5V logic levels (0V – logic low; 5V – logic high). Both inputs and outputs are ESD
protected but are not optoisolated; all input signals sent to the laser must be clean or conditioned by the
user. The figure below illustrates the pin arrangement of the DB-9 I/O (9-pin female D-type
subminiature) connector on the OEM vi30/40's rear panel while the following table provides connection
descriptions.
