What switch should I turn on to make the Spectra IV work with older coaxitron transmitters and third party control systems?

Issue

What switch should I turn on to make the Spectra IV work with Coaxitron and third party fiber?

The Spectra IV pan Speed are too slow and will not adjust on the Varispeed controller.

Product Line

Pelco Cameras

Environment

  • Spectra IV all models
  • Third party fiber transmitter and receivers compatible with Coaxitron
  • Speed issues

Cause

Spectra IV will only work when the Coaxitron signal is placed in the correct part of the blanking pulse of video.  Any influence on that portion of the spectrum can cause the Device not to control correctly or at all.

Resolution

Turn on SW2-3 on the Spectra IV dome drive for the following reasons:

  1. 3rd party Controllers or transmitters.
  2. Older Pelco Controllers.
  3. Long Cable runs approaching 600 feet or more.
