Issue
How is the D7038 or DS9484 configured to make all four outputs trip on one input?
Solution
Connect a supervised, 12 or 24 VDC NAC to input 1, terminals IN1-(terminal 14) and IN1+ (terminal 15). Then connect the EOL resistor for the input NAC to the second IN1+ (terminal 16) and EOL1 (terminal 17).
Input 2 (terminals 10 through 13) will not affect operation and can be left completely unconnected.
Set DIP switch 1 to the ON position.
**After making any DIP switch changes, to the D7038 or DS9484 the unit must be powered down and then back up for those changes to take effect.
