The device can be connected to a PC and operated with the
laboratory software labworldsoft
Note: Please observe the system requirements as well as
the operating instruction and help section of the software�
USB interface:
The Universal Serial Bus (USB) is a serial bus for connecting
the device to the PC� Equipped with USB devices can be con-
nected to a PC during operation (hot plugging)� Connected
devices and their properties are automatically recognized�
Use the USB interface in conjunction with labworldsoft
operation in "Remote" mode and also to update the firm-
ware�
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 through the USB data cable to the PC�
The data communication is via a virtual COM port�
The above details correspond as far as possible to the recommendations of the NAMUR working party (NAMUR rec-
ommendations 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 device and the PC� With a suitable terminal or communications programme these commands can be transmit-
ted directly to the device� The IKA software package, Labworldsoft
and collecting data under MS Windows, and includes graphical entry features, for motor speed ramps for example�
Commands
Function
IN_PV_2
Read the internal actual temperature
IN_SP_2
Read the internal setting temperature
IN_SP_3
Read the safety setting temperature
IN_SP_4
Read the flap setting
OUT_SP_2 X
Set the internal setting temperature, X = 0 to 250
OUT_SP_12@n
Setting WD safety limit temperature with set value echo
OUT_SP_4 X
Set the flap setting, X = 0 to 100
OUT_WD1@m
Watchdog mode 1: if event WD1 should occur, the heating functions are switched off and PC1 is
displayed� Set watchdog time to m (20 - 1,500) seconds, with watchdog time echo� This command
launches the watchdog function and must be transmitted within the set watchdog time�
OUT_WD2@m
Watchdog mode 2: if event WD2 should occur, the temperature target value is changed to the
WD safety temperature limit value� The warning PC2 is displayed� The WD2 event can be reset
with OUT_WD2@0 - this also stops the watchdog function� Set watchdog time to m (20 - 1,500)
seconds, with watchdog time echo� This command launches the watchdog function and must be
transmitted within the set watchdog time�
START_2
Start the heating function
STOP_2
Stop the heating function
RESET

Command syntax and format:
The following applies to the command set:
- Commands are generally sent from the computer (Master)
to the device (Slave)�
- The device sends only at the computer's request� Even
fault indications cannot be sent spontaneously from the
device to the computer (automation system)�
- Commands are transmitted in capital letters�
- Commands and parameters including successive parame-
ters 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 maxi-
mum length of 80 characters�
- The decimal separator in a number is a dot (Code: hex
0x2E)�
, provides a convenient tool for controlling the device
