The entry with key D4 in the unit directory (44Ch in this case) provides the offset for
unit dependent info:

44Ch + 000001 * 4 = 450h

And finally, the entry with key 40 (454h in this case) provides the offset for the camera
control register:

FFFF F00 3C0000h * 4 = FFFF F0F00000h

The base address of the camera control register is thus
FFFF F0F00000h.

The offset entered in the table always refers to the base address of F0F00000h.

L

This means that if you want to use the “DirectControl” program to read or write to a
register, the following value must be entered in the

Address

field:

“F0F Offset”

The following example should make this clear:

The camera has a temperature sensor. It measures the temperature and can be output at
any time in 0.1°C increments. The register with offset 82Ch is available for this. The
“Directcontrol” program can be used to read from this register.
