- Each individual command (incl. parameters and data) and each re-
sponse 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 recommenda-
tions 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 equip-
ment, 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 communica-
tions programme these commands can be transmitted directly to the
stirrer equipment. The IKA
® software package, labworldsoft ® , pro-
vides a convenient tool for controlling stirring equipment and collect-
ing data under MS Windows, and includes graphical entry features,
for motor speed ramps for example.
The following table summarises the (NAMUR) commands under-
stood by the IKA
® control equipment.
