• Each individual instruction including parameters and data as
well as each reply are terminated with CR LF (Code: hex
0x0D and 0x0A) and have a maximum lenght of 80 charac-
ters.
• The decimal separator in a floating point number is the point.
(Code: hex 0x2E)
The above statements largely correspond with the recommen-
dations of the NAMUR-Assocation (NAMUR-recommendati-
ons for the design of electric plug connections for the analog
and digital signal transmission to labortory - MSR individual
units. Rev. 1.1).
Overview of the NAMUR-instructions
Abbreviations:
X,y = numbering parameter (integer number)
m= variable value, integer
n= value of variable, floating point number
X=1 Pt1000 medium temperature (external temperature
sensor)
X=2 temperature (incubations room)
X=3 safety temperature
X=4 speed
X=6 safety speed
X=50 Pt1000.60 medium temperature sensor offset in K

NAMUR instuctions
Function
IN_NAME Input description name
IN_PV_X Reading the real value
X=1;2;3;4;
IN_SOFTWARE Input software ID number
date, version
IN_SP_X Reading the set rated value
X=1;2;3;4;6;12;
42;50;52;53;
IN_TYPE Input laboratory unit ID
OUT_NAME name
Output description name. (Max. 10 characters,
default: KS4000 ic)
OUT_SP_12@n Setting the WD safety temperature with the
echo of the set value
OUT_SP_42@n Setting the WD safety speed with the
echo of the set value
OUT_SP_X n Setting the rated value to n
X=1;2;4;50;52
OUT_WD1@m Watchdog mode 1: When a WD1 event occurs,
the heating and shaking functions are shutdown
and message PC 1 is displayed.
Set the watchdog time to m (20...1500) seconds,
with echo of the watchdog time. This instruction
starts the watchdog function and must be sent
within the set watchdog time.
OUT_WD2@m Watchdog mode 2: When a WD2 event occurs,
the speed setpoint will be set to the WD safety
setpoint speed and the temperature setpoint
will be set to the WD safety setpoint temperatu-
re. The PC 2 warning is displayed.
The WD2 event can be reset with OUT_WD2@0-
resetting also blocks the watchdog function. Set
the watchdog time to m (20...1500) secondes,
with echo of the watchdog time. This command
starts the watchdog function and must be sent
within the set watchdog time.
RESET Switching off the instrument function.
