Wiring the Autoiris (AC) Lens
AC lenses have two cables. One cable has a AMP MR (Miniature Rectangle) connector. This provides
connection for the zoom, focus and preset controls. Lenses without the preset function are supplied with a 6-pin
connector, while lenses with presets have a 9-pin connector. The wiring of both connectors is shown in Figure 2.
Table 4 shows the color-coding of the control cables and Table 5 shows the color coding for the control and
preset cables. The second cable is connected directly to the video drive connection on the camera and does not
have a connector. Most cameras provide either a screw terminal connector or a spring-loaded pushbutton
connector on the back of the camera for video-drive autoiris lenses. If the camera requires a separate connector
for the autoiris cable, it is supplied with the camera and should be wired according to the instructions provided
with the camera. The cable controlling the autoiris drive in an AC lens may consist of three or four conductors
and a shield. For proper operation, the shield of the cable MUST be grounded to the same pin as the black
(common) conductor. If the autoiris cable has four conductors, the green conductor is not used and may be cut
off. Table 6 shows the color coding for the autoiris cable.
