• CTS: (Pin 8) LOW (positive tension)
/ PC recipient
• CTS: (PIN 8) HIGH (negative tension)
/ PC not recipient
• Access method: Data communication from laboratory instru-
ment to processor is only possible on demand
of the processor.
Instruction Syntax
Note the following:
• The instructions are generally sent from the processor (master) to the
laboratory instrument (slave).
• The laboratory instrument exclusively sends on demand of the processor. Even
error codes cannot be spontaneously communicated from the laboratory instru
ment to the processor (automatic system).
• Instructions and parameters as well as subsequent parameters are separated by
at least one blank. (Code: hex 0x20)
• 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 characters.
• The decimal separator in a floating point number is the point (Code: hex 0x2E).
The above statements largely correspond with the recommendations of the
NAMUR-Association. (NAMUR-recommendations for the design of electric plug
connections for the analog and digital signal transmission to laboratory- MSR
individual units. Rev. 1.1)

NAMUR Instructions Function
IN_PV_X X=4 Reading the real-value
OUT_SP_Xn X=4 Setting the actual value to n
up to a maximum of the set
upper speed limit
IN_SP_X X=4; 6 Reading the set rated value
START_X X=4 Starting the instrument's
(remote) function
STOP_X X=4 Switching off the instrument
function. Variables set with
OUT_SP_X are maintained. Con-
tains the instruction MP_STOP
RESET Switching off the instrument
function
STATUS Display of status
