3.7.4.1 Configuration
The Machine Interface laser inputs and laser outputs may be configured as sinking or
sourcing. There are two switches on the M/C interface panel that individually set the inputs
and outputs as sinking or sourcing.
3.7.4.2 Switches in SINK Position
When the I/P switch is set to SINK, the external Controller output must “pull” current through
the laser input. Likewise, when the O/P switch is set to SINK, the external Controller input
must “pull” current through the laser output.
