IKA ULTRA_TURRAX Mode D'emploi page 20

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. Configuration, command
syntax and commands of the virtual COM ports are as described
in RS 232 interface.
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 in-
dications cannot be sent spontaneously from the 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 recommen-
dations 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. 2.9).
The NAMUR commands and the additional specific IKA commands
commissioning serve only as low level commands for communica-
tion between the tube driver and the PC. With a suitable terminal
or communications program these commands can be transmitted
directly to the tube driver. The IKA software package, labworldsoft,
provides a convenient tool for controlling tube driver and collecting
data under MS Windows, and includes graphical entry features, for
motor speed ramps for example.
The following table summarize the (NAMUR) commands under-
stood by the tube drive control up to Version 2.9.
