2.4. Laser Interface (TB102)

The Laser Interface connector (two 8-pin, terminal block-style connectors) provides connections to the laser
control outputs as well as the ESTOP sense input. There are three laser output signals and they are
available in optically-isolated open drain/open source format or as RS-422 differential signals. The open drain
/ open source setting is a factory configured option.
N O T E : The three laser outputs are configured in the software; refer to the A3200 Help file for more
information.
The active polarity of the laser output signals is set using Switch S1 located on the top edge of the Nmark
CLS (see Section 2.12.). In the "OFF" position, the output transistor is turned on to activate the laser (this is
the Normally-Open (N.O.) configuration).
The opposite polarity (Normally Closed (N.C.)) can be selected by moving the switch to the "ON" position.
This state is not maintained while the Nmark is powered off and it is not considered fail-safe.
W A R N I N G : The installer of this product is responsible for providing operator safeguarding
measures. Please refer to your laser manual for additional information.
Jumpers JP4-JP9 are set at the factory for sinking (-SINK) or sourcing (-SRC) operation and cannot be
changed in the field.
The connector pin assignment is shown below and the following figures show electrical connection options.
