LENS

The camera can accommodate a wide selec- tion of lenses, these lenses include manual iris lenses (see ESC FUNCTION), DC controlled iris lenses, and “Standard” video controlled iris lenses.

A. ELECTRICAL CONNECTIONS

Table 1 shows two different wiring schemes for the 4pin Auto-iris connector.

If a “Standard” auto-iris is to be used, see “(1) VIDEO SIGNAL CONTROL”. (Table 1)

For DC controlled iris, use “(2) DC VOLTAGE DRIVE”.

CAUTION:

The output power for auto-iris lens is +9 VDC and the maximum current capacity is 40 mA.

When using an auto-iris lens requiring voltage and current other than specified, supply lens power only from an external power supply.

Set the Esc switch (#2 switch of Dip Switch) to “OFF“ when using an auto-iris lens type.
