Connector P1

Connector P1 is not used for this design.

Notes

Limit switches
- GX-12/2 plug
- Normally Closed (NC) switch are recommended.
- When set to Normally Open (NO) in the Rose Engine Butler Settings program, LinuxCNC reads the card's inverted input for that pin (.in_not instead of .in), so no NOT function is needed.
- See also,
  - Limit Switch Cabling
E-Stop Button
- GX-16/2 plug
- E-stop button must be a Normally Closed (NC) switch
- See also,
  - E-stop Button Cabling
Breakout Power
- For more information on jumper W4, see 7I92 Ethernet Anything I/O Manual, pg. 2
Signal Tower
- GX-12/4 plug
- Active low from 7i92
- See also,
Signal Tower Red Light
- On after a following error or limit trip.
Signal Tower Green Light
- On while a program or MDI command runs.
Signal Tower Buzzer
- On when a sound is needed.
