Geysitech (Bayern-Hessen) Protocol
Geysitech Commands
D-6 Model 49i Instruction Manual
Exponent: sign and 2 digits.
Example:
-5384000.0is represented as -5384+06
+0.04567is represented as +4567-02
<status>: is formed by < operating status > and < error status > and separated
by a space i.e.
<operating status><SP><error status>
Each of the two (<operating status> and <error status>) are formed by two
characters each representing a 2 digit hex number which is one byte (8 Bits)
operation status and one byte (8 Bits) error status.
These two bytes contain the information about the main operating
conditions of the instrument at that instant. For details on how to interpret
the status bytes refer to
<SFKT>: is the space provided for future use for special function, it
currently contains a string of ten 0's i.e. <0000000000>.
Example:
Geysitech Protocol with transmission of three concentrations (Instrument
ID is 1, Operation Status is 03, Error Status is 04):
