Geo MACRO Drive User Manual
36 Connections
EnDat Interface
The Geo Drive will read the absolute data from the EnDat ( En coder Dat a) interface only if the
appropriate option is ordered. (Not yet released firmware)
Hardware Setup
The differential format provides a means of
using twisted pair wiring that allows for
better noise immunity when wired into
machinery.
The wiring diagram to the right shows an
example of how to connect the Geo Drive to
an EnDat interface.

Note: We assume the EnDat
Interface power requirements are
for 5V, else use of an external
power supply for the EnDat is
required. Tie together the Geo
Drive GND and the power supply
GND for noise immunity.
