PPpretested cable you must reverse the left/right and up/down function pins as shown in Figure 1.
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/
PPfactory 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
