Interfaces And Outputs - IKA EUROSTAR 60 control Betriebsanleitung

The device can be operated in "Remote" mode via an RS 232 or
USB interface using the laboratory software labworldsoft
The RS 232 interface at the back of the device is fitted with a
9-pole SUB-D port which can be connected to a PC. The pins are
assigned serial signals.
The USB port at the rear of the stirrer is used for the connection
between the PC and the Wireless Controller (WiCo). The Wireless
Controller also has a USB port, located on its right side. It can also
be used to connect to a PC for "remote control".
Note: Please comply with the system requirements together with the
operating instructions and help section included with the software.
USB interface
The Universal Serial Bus (USB) is a serial bus system which allows
the stirrer to be connected to the PC. Devices that support USB
can be connected to each other whilst they are running (hot plug-
ging) and provide automatic recognition of the connected devices
and their properties.
Use the USB interface in conjunction with labworldsoft
tion in "Remote" mode and for loading the update.
To load the update, open http://www.ika.net/ika/lws/download/
EUROSTAR.cfg.
Installation
Once the EUROSTAR 60 / 100 control is connected to the PC
using the USB data cable, it will then transmit information to the
Windows operating system to tell it which device drivers are re-
quired. Windows will then either:
- Load the driver
- Install the driver automatically, if it is not already installed
- Prompt the user to perform a manual installation

Serial interface RS 232 (V24)
Configuration
- The functions of the interface connections between the stirrer ma-
chine and the automation system are chosen from the signals speci-
fied in EIA standard RS 232 in accordance with DIN 66 020 Part 1.
- For the electrical characteristics of the interface and the alloca-
tion of signal status, standard RS 232 applies in accordance with
DIN 66 259 Part 1.
- Transmission procedure: asynchronous character transmission in
start-stop mode.
- Type of transmission: full duplex.
- Character format: character representation in accordance with
data format in DIN 66 022 for start-stop mode. 1 start bit; 7
character bits; 1 parity bit (even); 1 stop bit.
- Transmission speed: 9600 bit/s.
- Data flow control: none
- Access procedure: data transfer from the stirrer machine to the
computer takes place only at the computer's request.

Command syntax and format
. The following applies to the command set:
®
- Commands are generally sent from the computer (Master) to the
stirrer machine (Slave).
- The stirrer machine sends only at the computer's request. Even
fault indications cannot be sent spontaneously from the stirrer
machine to the computer (automation system).
- Commands are transmitted in capital letters.
- Commands and parameters including successive parameters are
separated by at least one space (Code: hex 0x20).
- Each individual command (incl. parameters and data) and each
response are terminated with Blank CR Blank LF (Code: hex 0x20
hex 0x0d hex 0x20 hex 0x0A) and have a maximum length of
80 characters.
- The decimal separator in a number is a dot (Code: hex 0x2E).
The above details correspond as far as possible to the recommen-
dations of the NAMUR working party (NAMUR recommendations
for the design of electrical plug connections for analogue and
® for opera-
digital signal transmission on individual items of laboratory control
equipment, rev. 1.1).
The NAMUR commands and the additional specific IKA
mmands serve only as low level commands for communication
between the stirrer machine and the PC. With a suitable terminal
or communications programme these commands can be transmit-
ted directly to the stirrer equipment. The IKA
