2.0 DESCRIPTION
The Coaxitron® receiver/driver operates on the principle of transferring control in- formation and video on the same line. A train of pulses containing control informa- tion is superimposed on the video at VIS time. This transmitted train of control infor- mation can originate from a variety of Pelco controllers, including the CM6700, CM7500, CM8500, CM9500,
Depending on receiver/driver options, wiring and controller capabilities, the pos- sible range of control information that can be transferred, acted upon and aug- mented by the receiver is covered by the following list of functions:
1. Pan Left | 9. | Iris Open |
2. Pan Right | 10. | Iris Close |
3. Tilt Up | 11. | Camera Power On/Off |
