STROBE**
Head case ground shown connected to signal ground via the IntelliHead connector. It is better to
connect the head case ground directly to a separate earth ground if possible, bypassing the closely
spaced PCB connector terminals. If this is not possible, as is the case in many designs, then the
next best thing is to pass the earth ground through the board on its way to earth. Tying earth
ground to signal ground on the PCB is often done, but problems can arise in the case of extreme ESD
events.
Note that the signal
wires do not exit the
potting material of the
IntelliHead in the
orderly arrangement
implied above.

CASE
* The DATA line must be connected to an OPEN DRAIN OUTPUT/INPUT pin.
** STROBE must be an interrupt pin (or polled at least every 100ms) and tri-stateable.
For future compatibility with MagnePrint, the MCU must respond to the interrput and take
STROBE low within 25 us.
