Each axis connected to the UMI-7774/7772 has a 25-pin D-SUB feedback
connector to which you can wire incremental encoders, limits, and home
sensors. The feedback connectors for axes 1 and 2 have additional
connections for Hall effect sensors for brushless motors. Figure 3-5 shows
the pin locations of the feedback connector for each axis. Table 3-5 shows
the corresponding signals for each pin.
