Leica SmartTouch™ Manual 16
Encoded and Unencoded Components
The Leica M series has various encoded
and motorized components; this means
that the current status of a component is auto-
matically transmitted to the Leica SmartTouch™.
These data are displayed on the control panel
and included in various calculations. At the
same time, it is possible to control motorized
components remotely via the Leica Smart-
Touch™.
Encoded components
For example, if you adjust the encoded iris
diaphragm on a Leica M205 C using the dial,
the size of the aperture is automatically trans-
mitted to the Leica SmartTouch™. The transmit-
ted value is then used to calculate and display
the depth of field, for example.
For some instruments, such as the Leica M205
A, this also works the other way around: the iris
diaphragm can be opened and closed by input
on the Leica SmartTouch™.
Unencoded components
Not all components of the M series are encoded.
The objectives, spacer rings and eyepieces are
among the unencoded elements.
To ensure that these unencoded elements are
included in the various calculations correctly,
a one-time configuration of these elements is
required. For instructions, refer to page 24.
If an unencoded component is replaced
with another component, this compo-
nent must be detected correctly – otherwise,
the Leica SmartTouch™ will show incorrect
values on the display.
