CCI.TECU – Introduction
1.3 About CCI.TECU
A vast range of electronic components are used in modern tractors. In addition to
sensors for the capture of operating data these are, above all, comprised of
electronic control units (ECUs) for the control of various tractor functions. The
electronic components are, as a rule, interconnected via a so-called bus system
and use this to exchange tractor information such as driving speed or power take
off speed.
The tractor ECU (TECU) is required so that information such as driving speed,
power take off speed or the current position of the 3-point hitch can also be made
available to an ISOBUS implement.
On an ISOBUS tractor, the TECU establishes the connection between the tractor
bus system and the ISOBUS and thus provides the implement with the
aforementioned information.
New tractors are often already ISOBUS-compatible ex works and fitted with a
TECU. Such TECUs are hereinafter identified as primary TECUs.
The vast majority of tractors in use are, however, not ISOBUS-compatible but can
be retrofitted using an upgrade cable set. However these cable sets do not usually
include a TECU, i.e. the connection from ISOBUS implements is possible but
access to tractor information is not.
The CCI.TECU described in these operating instructions closes this loophole. The
app concerned is an upgrade solution.
Using CCI.TECU, tractor information is read out via the signal connector and
transferred to the ISOBUS implement.
