The Arrow
fx
has a removeable encoder housing which allows
for easy serviceability. The encoder housing contains the Read
heads which intrepret the coordonates from the magnetic rings
located on the pan and tilt modules on the fluid head.
To remove the encoder housing simply unscrew the 2 x M5
screws (fig. 5).
The encoder housing contains the ports (RJ 45) for pan and tilt
output (fig. 6). The housing has a LED lights to indicate correct
RJ45 connection (green) and the reference point on the magnetic
ring (red).

Output Diagram
The output signal from the Arrow
fx
fluid head is a pulse
signal (A,-A, B, -B) with a reference signal (Z,-Z) (one count
per revolution). The interface box then transmits this
calibrated information to your downstream workflow.
