Interface connections
Sample output circuit
You can monitor OEM v30 laser status remotely by connecting one or more outputs to an
isolated 5 VDC solid state relay or PLC input module. Figure below illustrates the connec-
tions required to monitor the DB-9’s Lase Indicator status, or any other DB-9 output, using an
isolated 5 VDC input module.

Lase Indicator output to PLC input
Interface B (RJ45) connector
The Interface B (RJ45) connector provides a +15 VDC auxiliary output (DC Out), a PWM input, an en-
able input, and three status outputs. The user inputs, Laser Enable and PWM Positive/PWM Negative,
enable lasing and provide output power control. User outputs indicate v30 ready, 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

damage
Turn off DC power before installing or removing any plug or cable
from the Interface B (RJ45) 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.
Figure below illustrates the pin arrangement of the Interface B (RJ45/8P8C) connector on the OEM v30’s
rear panel while Table 3-6 on the next page provides connection descriptions.
