To install and test the pan/tilt you will need to assemble the connector parts pro-
vided. Refer to Section 3.3 for connector assembly.

The PT280 series pan/tilts are prewired for all control functions (pan/tilt, motorized
zoom lens, 24 VAC camera power, and video. All connections are made at the input
connector, eliminating the need for wiring harnesses made in the field. When using
Coaxitron Control Systems, consider using the C1906, C1906/PP, C1925 or C1925/
PP factory assembled pretested cables which are wired for inverted applications.
Wire the control cable per the wiring diagram provided in the PT280 Series Pan/Tilt
manual, C324M, for the specific pan/tilt you are using. (The PT280-24P basic pan/
tilt wiring diagram is included in this manual for reference only.)

If you are not using the

C1906, C1906/PP, C1925, or C1925/
PP pretested cable you must reverse
the left/right and up/down function
pins as shown in Figure 1.
