2 QUICK START
2.1 Overview
As shown in Figure 1, the pan-tilt unit is connected to the pan-tilt controller. Power for the
controller can be supplied from an optional AC/DC power supply or a battery power source. The
pan-tilt controller accepts commands via RS-232 from a host computer, and it drives the position
of the pan-tilt unit. A pan-tilt controller can be connected to other controllers via a multidrop RS-
485 network so that a single host computer serial port can control multiple pan-tilt units.
