/// USB interface
The device can be connected to a PC and operated with the laboratory
software labworldsoft through USB interface.
Please comply with the system requirements together with the
operating instructions and help section included with the software.
The Universal Serial Bus (USB) is a serial bus for connecting the device to the
PC. Devices equipped with USB can be connected to a PC during operation
(hot plugging). Connected devices and their properties are automatically
recognized. Use the USB interface in conjunction with labworldsoft for
operation in „Remote“ mode and also to update the firmware.
/// Installation
First, download the latest driver for IKA devices with USB interface from:
http://www.ika.com/ika/lws/download/usb-driver.zip
. Install the driver
by running the setup file. Then connect the IKA device through the USB data
cable to the PC. The data communication is via a virtual COM port.

/// 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: 0
×
20).
› Each individual command (incl. parameters and data) and each response
are terminated with Blank CR LF (Code: 0
×
20 0
×
0d 0
×
20 0
×
0A) and
have a maximum length of 80 characters.
› The decimal separator in a number is a dot (Code: 0
×
2E).
The above details correspond as far as possible to the recommendations
of the NAMUR working party (NAMUR recommendations for the design of
electrical plug connections for analogue and digital signal transmission on
individual items of laboratory control equipment, rev. 1.1).
The NAMUR commands and the additional specific IKA co 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 transmitted directly to the stirrer equipment. The IKA
software package, labworldsoft, provides a convenient tool for controlling
stirring equipment and collecting data under MS Windows, and includes
graphical entry features, for motor speed ramps for example.
