1 Introduction
1.1 Preface
Please read this interface description before commissioning the interfaces for
the instrument. Keep the interface description in a place which is accessible to
all users at all times.
Please assist us to improve this interface description, where necessary.
Your comments will be appreciated.

All the necessary information for operating the interface is
contained in this interface description. However, if any difficulties
should still arise during start-up, please do not carry out any
unauthorized manipulations. You could endanger your rights under
the instrument warranty!
Please contact the nearest subsidiary or the head office in such a
case.
E
When returning modules, assemblies or components, the
regulations of EN 100 015 “Protection of electrostatically sensitive
components” must be observed. Use only the appropriate ESD
packaging for transport.
Please note that we cannot accept any liability for damage caused
by ESD.
ESD = electrostatic discharge

1.2 Typographical conventions
1.2.1 Warning signs
The symbols for Danger and Caution are used in these operating instructions
under the following conditions:
1.2.2 Note signs
1.2.3 Representation modes
Danger This symbol is used when there may be danger to personnel if
the instructions are ignored or not followed correctly!
Caution This symbol is used when there may be damage to equipment
or data if the instructions are ignored or not followed correctly.
E
Caution This symbol is used where special care is required when
handling components liable to damage through electrostatic
discharge.
Note This symbol is used when your special attention is drawn to a
remark.
abc1Footnote Footnotes are remarks that refer to specific points in the text.
Footnotes consist of two parts:
A marker in the text, and the footnote text.
The markers in the text are arranged as continuous superscript
numbers.
0x0010 Hexadecimal
number A hexadecimal number is identified by being preceded by an “0x” (here: 16 decimal).

2 General
2.1 Areas of application
The paperless recorder has several interfaces:
- as standard: a TTL setup connector on the front panel, and on the back
(only for a Modbus slave)
- as standard: serial interface RS232 or RS485 (Modbus slave, Modbus
master, bar code)
for communication with the bus system or a PC. This can be used to read
out measurements or other device and process data from the paperless
recorder.
- as standard: Ethernet 10/100 Mbit/sec
for communication with the instrument via a network (setup, browser,
Modbus-TCP, e-mail alarm)
- optionally: serial interface RS232
for the connection of a bar code reader (Modbus slave, Modbus master, bar
code)
2.2 System requirements
The following items are required for operating the serial interface:
- Connecting cable:
for RS232 / RS485 e.g.
PC interface
with TTL/RS232 converter and adapter Part No. 70/00350260
PC interface
with USB/RS232 converter and adapter Part No. 70/00456352
for Ethernet interface, e.g.
RJ 45 patch cable, CAT 5 or better (crossover)
- setup or evaluation program, e.g.
setup program: Part No. 70/00468991
PC evaluation software PCA3000 Part No. 70/00431882
PCA communications software PCC Part No. 70/00431879
JUMO SVS-2000 visualization: data sheet 70.0753
- PC or notebook
2.3 Identifying the interface
The interface for RS232 or RS485 and the Ethernet interface are available in
every instrument.
The RS232 serial interface for connecting a bar code reader and the Profibus-
DP interface are options.

To see whether the instrument already has an additional option interface, use the
menu Device info !Hardware to check.

Setup interface
Use either the setup interface on the front panel or the setup
interface on the back!
The connection on the front panel can only be made through the
setup interface with the connecting cable for “PC interface with
TTL/RS232 converter and adapter”, Part No. 70/00350260.
If the PC or notebook does not have a serial interface, then the
connecting cable “PC interface with USB/RS232 converter and
adapter”, is also required (Part No. 70/00456352).
The transmission parameters for the interface are fixed in the
instrument, and cannot be altered.
- baud rate = 9600 bps
- data format = 8 data bits, 1 stop bit, no parity
