Data transfer via IR interface
The heating bath transfers data via IR interfaces� These interfaces are located on the left display
side of the heating bath or on the right side of the drive unit� Do not place any objects between
the two operating units as otherwise the data transfer may be interrupted!
Remote Mode
Using the laboratory device software "labworldsoft
control the device can be operated in "Remote" mode� In this mode, the device can no longer be
hand-operated� (Fig� 12)
Note: Please comply with the system requirements together with the operating instructions and
help section included with the software�

/// USB interface:
The connected devices and their properties are detected automatically� The USB interface is
used in conjunction with software control for "remote" operation and can also be used for
software update of the device�
www.
/// USB device drivers:
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 to the PC via the USB
data cable and follow the instructions�
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 lab device (Slave)�
- The lab device sends only at the computer's request� Even fault indications cannot be sent
spontaneously from the lab device 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 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 recommendations of the NAMUR work-
ing 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 commands serve only as low level
commands for communication between the lab device and the PC� With a suitable terminal or
communications program these commands can be transmitted directly to the lab device� The
IKA software package, labworldsoft
collecting data under MS Windows, and includes graphical entry features, for motor speed
ramps for example�
The following table summarises the (NAMUR) commands understood by the IKA equipment�
