Interface connections
The Interface connections section includes subsections:
■ Interface A (DB-9) connector
■ Interface B (RJ45) connector
Two built-in interface options are available for integrating OEM v30 lasers—a DB-9 and an RJ45 interface
connector. The RJ45 (Interface B) connector is useful when integrating v30’s into existing integrated laser
systems previously congured for an RJ45 interface. For new Firestar OEM v30 installations, use the DB-9
(Interface A) connector. Although both interface connectors provide the same functionality, the DB-9
connector contains an additional output, Lase Indicator, that activates when the v30 is actively lasing.
Interface A (DB-9) connector
The Interface A (DB-9) connector provides a +5 VDC auxiliary output (DC Out), a PWM input, an en-
able 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 v30 ready, lase, over temperature,
and input voltage status. 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.
Caution
possible
equipment
damage
Turn o DC power before installing or removing any plug or cable
from the Interface A (DB-9) connector. Ensure that user connections
are made to the appropriate pins and that the appropriate signal
levels are applied. Failure to do so may damage the laser.

connector on the OEM v30’s rear panel while the following table on the next page provides connection
descriptions.
