both the Matrox 4Sight EV6 auxiliary output and the serial resistor to make sure
that the voltage seen at the input of the sinking field device can reliably assure the
detection of a high logical state.
The diagram below illustrates the difference between connecting a sinking field
device to Matrox 4Sight GPm and connecting it to Matrox 4Sight EV6:
PREVIOUS: Matrox 4Sight GPm auxiliary output wired to a sinking field device requiring a pull-up resistor

in a sinking configuration
NEW: Matrox 4Sight EV6 auxiliary output wired to a sinking field device requiring a serial resistor
+
Up to 24V
–

in a sourcing
 Note that with the above wiring modification, there will be a logical inversion to
take into consideration. The sinking field device will not detect an ON condition
when the Matrox 4Sight EV6 auxiliary output is closed.
