INSTALLATION
The lens must be either a C- or CS-mount type of less than 2.2 pounds (1 kg). The protru-
sion behind the mounting surface must be within the limits as shown in Figure 3.
The camera is supplied with a lens connector for inserting the power and control cable of
an auto iris lens. Before connecting an auto iris lens, however, you first have to replace the
lens cable plug with the one supplied with this camera. To replace the plug:
a.
Detach the old plug from the lens cable.
b.
Solder the wires to the pins of the new plug (refer to Figure 4). For cable pin as-
signments, refer to the instruction manual for the lens.
