HAll the necessary information for operating the interface is con-
tained in these operating instructions. However, if any problems
should still arise during start-up, you are asked not to carry out any
prohibited manipulations. You could endanger your rights under
the warranty!
Please contact the nearest subsidiary or the main factory.
EWhen returning chassis, modules or components, the rules of
EN 100 015 “Protection of electrostatically sensitive devices” have
to be observed. Use only the appropriate ESD packaging material
for transport.
Please note that we cannot be held liable for any damage caused
by ESD (electrostatic discharges).

1.2 Typographical conventions
1.2.1 Warning signs
The signs for Danger and Warning 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 accurately!
!Warning This symbol is used when there may be danger to equipment
or data if the instructions are disregarded or not followed accu-
rately!
EWarning This symbol is used where special care is required when han-
dling components liable to damage through electrostatic dis-
charges.
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 raised
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 General
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 screen recorder
functionality.
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 screen recorder :
- Screen recorder with LON interface
( program version1from 100.02.01)
- 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. An interface cable is required for connecting mTRON modu-
les to a PC.
1. The program version can be requested in the menus of the screen recorder via
Instrument info #Version number.
HThe JUMO mTRON-iTOOL project design software can only be
dispensed with if the mTRON modules have been configured by
M.K. JUCHHEIM GmbH & Co prior to delivery. In order for this to
happen, the customer must have specified the required configura-
tion in detail when ordering his measuring system.
HThe screen recorder can also operate without internal analogue
channels. In this case, the measurements are obtained exclusively
from the mTRON modules.

2.3 Identifying the interface
The LON interface is available as extra Code. The contents of the menu
Instrument info rInterface show whether it is implemented in the system.
If the entry Instrument info rExt. I/O supplement is set to Yes, the LON inter-
face is available.

3 Connecting the interface
3.1 Connection diagram
The screen 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 in-
structions for the mTRON modules. Further information on bus termination
can be taken from the Section 3.2 “Connecting configured mTRON modules”.

Connection

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 instrument and process data,
can be read out from the screen recorder with the aid of the serial
interface. The connection and functionality of the serial interface
are explained in detail in the Interface Description B 95.5010.2.2.

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