commands on Port B1. In this mode Port B2 provides differential buffered pulse-and-direction
outputs for another axis.
Below are the signals on the Auxiliary Feedback ports when set up to run as a single-ended
pulse-and-direction input:

Table 11: Pulse-and-Direction Auxiliary Encoder Pin Assignment on FEEDBACK B
FEEDBACK B on the “top” of the Falcon has a 15-pin high density D-Sub socket. Connect the
Auxiliary Feedback cable from the Pulse and Direction Controller to FEEDBACK B using a 15-pin,
high density D-Sub plug with a metal housing. When assembling the Auxiliary Feedback cable,
follow the instructions in Section 3.4.4 (Feedback and Control Cable Assemblies).
