Continuous output after power On: COF128 to COF 140
If the decimal number 128 is added to the above stated output formats COF0...COF12, then the AED is
switched into the continuous output mode. After the power On or RES command, the AED outputs the
measured values without MSV? request. The continuous output can be switched off with the command STP .
The setting is made with the following entries ( COF 
≥
128):
1. ... make necessary settings
2. ICRi; set measuring rate of the AED
3. COFx+128; the AED transmits measured values continuously,
time interval corresponding to ICR, x=0...12
4. STP; stop continuous transmission
5. TDD1; store protected against power failure
6. COFx+128; the AED transmits measured values continuously,
time interval corresponding to ICR .
The AED starts with the measured value output without separate request also after switching on the voltage.
These output formats have another special feature (depending on how triggering is set, command TRC ):
Trigger deactivated: continuous automatic measured value output
Trigger activated: automatic measured value output only if a new measured value has been
created after triggering (MAV? output value).
Output speed of measured values:
The AD104 can output a maximum of 100 measured values per second. This data rate also depends upon the
baud rate (BDR), the data format of the measured value output and the set averaging ( ICR ).
Table 1 shows this relationship in the continuous measured value output ( MSV?0 ):

Note for the evaluation of the binary measured values:
The binary codes for CR and LF can occur inside the bytes representing the measured value in the measured
value output in binary format. Therefore the contents of the measured value output must not be tested for the
characters CR/LF in order possibly to check the end of the measured value transmission. Rather the number of
characters which are received should be registered for the binary output. The control characters CR/LF are also
appended to the measured value in the binary output (sole exception:
MSV?0;).
