1.1 Preface
Warranty
Data backup
Update CD
for paperless
recorder
For interlinking the modules, you will need the JUMO mTRON-iTOOL project
design software, which has been created especially for devices from the
mTRON series.
For this reason, the driver data for the paperless recorder must be re-installed
in the module library.
Operating
Instructions
B 70.6570.2.1
HIf any problems should arise during start-up, you are asked not to
carry out any manipulations on the unit. You could endanger your
rights under the warranty. Please contact the nearest subsidiary or
the head office in such a case.
ABack up your configuration files at regular intervals.
If you reformat the hard disk, the projects that you have created with
the JUMO mTRON-iTOOL will also be deleted!
HAll necessary information for operating the interface is contained in
these operating instructions.
Please read this manual before starting up the interface. Keep the
manual in a place which is accessible to all users at all times.
Please assist us to improve this manual, where necessary.

1.2 Typographical conventions
1.2.1 Warning signs
The signs for Danger and Caution are used in this manual under the following
conditions:
1.2.2 Note signs
1.2.3 Presentation
VDanger This symbol is used when there may be danger to personnel if
the instructions are disregarded or not followed correctly!
!Caution This symbol is used when there may be damage to equipment
or data if the instructions are disregarded or not followed cor-
rectly!
ECaution This symbol is used where special care is required when han-
dling components liable to damage through electrostatic dis-
charge.
HNote This symbol is used when your attention is drawn to a special
remark.
"Reference This sign refers to further information in other handbooks,
chapters or sections.
abc1Footnote Footnotes are notes which refer to certain points in the text.
Footnotes consist of two parts:
Marking in the text and the footnote text.
The markings in the text are arranged as continuous super-
script numbers.
The footnote text (in smaller typeface) is placed at the bottom
of the text and starts with a number and a full stop.
0x0010 Hexadecimal
number A hexadecimal number is identified by being preceded by a
“0x” (here: 16 decimal).

2.1 Applications
The LON interface is available for the connection of external modules of the
JUMO mTRON automation system, in order to expand the functionality of the
paperless recorder.
All mTRON modules can be connected.
2.2 System requirements
The following requirements have to be met for the connection of external mo-
dules to the recorder :
- Paperless recorder with LON interface
- Configured modules of the JUMO mTRON automation system
2.2.1 Configuring the mTRON modules
The mTRON modules are configured using the JUMO mTRON-iTOOL project
design software. A setup interface is required for connecting mTRON modules
to a PC.
HThe JUMO mTRON-iTOOL project design software can only be
dispensed with if the mTRON modules have been configured by
JUMO GmbH & Co. KG prior to delivery. In order for this to happen,
the customer must have specified the required configuration in de-
tail when ordering his measuring system.
HThe recorder can also operate without internal (built-in) analog
channels. In this case, the measurements are obtained exclusively
from the mTRON modules.

2.3 Identifying the interface
The LON interface is available as an extra. The contents of the menu
Device info rInterface show whether it is implemented in the system.
If the entry Device info rInterface 21 is set to “ExtExpansion”, the LON inter-
face is available.

3 Connecting the interface
3.1 Connection diagram
The recorder is connected to the modules of the “JUMO mTRON automation
system” series using the connections Net_A and Net_B. The technical details
are described in the corresponding installation instructions for the mTRON
modules. Further information on bus termination can be taken from Chapter
3.2 “Connecting configured mTRON modules”.

Connection
diagram
HWhen connecting the LON interface, care must be taken not to mix
up connectors 20 and 21. Connector 20 is reserved for the serial
interface. Measurements, as well as device and process data, can
be read out from the recorder with the aid of the serial interface.
The connection and functionality of the serial interface are ex-
plained in detail in the Interface Description B 70.6570.2.0.

3.2 Connecting configured mTRON modules
The mTRON modules are connected to the recorder using a screened twisted
pair. The pre-configured mTRON modules are labelled according to customer
specification.
Example: 1 paperless recorder and 2 analog input modules
In the example shown, two analog input modules are connected to the record-
er in the “line structure” type of connection. The physical ends (recorder and
module 2) must be fitted with a termination resistor.
The bus termination resistor (50Ω) of the recorder is activated through a wire
link between pin 4 and pin 8 (see Chapter 3.1 “Connection diagram”).
Further details on the bus termination of the analog input modules can be ob-
tained from the installation instructions for the modules.
