Description of the computer
Computers with black plastic end plates have
program “version 8.xx” installed.
These computers can be operated with HORSCH
terminals, external ISOBUS terminals and with
ISOBUS compatible tractor terminals.
Machines with two computers
On machines with two metering drives two
computers are installed in the machine and
tightly connected together with a cable.
On drills which are temporarily combined with
an additional metering drive, like DuoDrill or
Maistro, the computers of both machines are
connected with a 16-pin plug.
The socket of this connection has an integrated
ISO-Bus termination and can thus can only be
replaced by an original cable in case of a repair.
Computer version
The computer is available in three dierent
hardware versions, whereby two of these
versions look optically exactly the same. It is
therefore very important to look for the article
numbers when carrying out repair work.

two computers
¾Supports the main computer in the control of
the third metering drive

Programs
The programs can be identied by their ending,
e.g. 8.xx 49 for the master version and 8.xx 4a
in the slave version. This ending can only be
recognized during programming.
On machines with dual computers the new and
old computer versions must not be combined.
When replacing an old computer it may be
necessary to replace both computers.
The programs in both computers must also be of
the same version, e.g. 8.52 49 only with 8.52 4a.
In case of incorrectly combined program
versions errors and malfunctions may
occur.
