5. FUNCTIONS
The SCB-1 can be controlled through a key-matrix or via RS-232 (SCOTI).
With the WolfVision SCB-1 Interface board the basic control functions can be done for
evaluation-purposes.
5.1 ZOOM
The SCB-1 uses an 12x zoom lens as well as a 2x digital zoom.
Optical 12x, f=5.8 to 69.6 mm (F=2.8 to 3.0)
The digital zoom is automatically switched ON at the tele end of 12x optical zoom range,
with progressive effect from 1 to 2, giving a total maximum 24x zoom ratio. Digital zoom
increases the picture element size and reduces the resolution.

The minimum focus distance (MOD) is below 50mm at optical wide end and below 500mm
at optical tele end, and is independent of digital zoom. If shorter distance are necessary, a high
quality close up lens is available (see optional accessories). An Auto-Focus (AF) function is
also available (enabled by default).
