Encoded And Unencoded Components - Leica SmartTouch Manual

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.
Leica SmartTouch™
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.
