• RTS: (Pin 7) LOW (positive tension)
/ PC may send
• RTS: (Pin 7) HIGH (negative tension)
/ PC may not send
• CTS: (Pin 8) LOW (positive tension)
/ PC recipient
• CTS: (PIN 8) HIGH (negative tension)
/ PC not recipient
• Access method: Data communication from laboratory instrument to
processor is only possible on demand of the processor.
Instruction Syntax
Here applies 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 proces-
sor. Even error codes cannot be spontaneously communicated from the
laboratory instrument to the processor (automatic system).
• Instructions and parameters as well as subsequent parameters are sepa-
rated 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 desing of electric
plug connections for the analog and digital signaltransmission to laboratory-
MSR individual units. Rev. 1.1)
