Parameters
Addressable parameters
The following parameters can be read or modified with telegrams
SD2 and SD3 (see corresponding sections on pages 7 and 8).
To be able to do this, a parameter field address (see table on
the right), the parameter address (offset, page 10) and the code
of the parameter value are required.
For example
The following information is required for the first chart speed:
Parameter field address
Parameter address (offset)
Code for the chart speed 20 mm/h
Parameter field address
Instrument function group
System parameterisation
Parameterisation, channel 1
Parameterisation, channal 2
Parameterisation, channel 3
Parameterisation, channel 4
Parameterisation, channel 5

Communication error register
The above-named addresses are input into the appropriate fields
of a message during communication. From the address, the re-
corder determines the data range to be transmitted. The data
transmission takes place with messages in the SD2 and SD3
formats. To read a data field, FC = 15H must always be used,
FC = 16H must be used to write a data field. If invalid parameter
values are contained in a message, the negative acknowledge-
ment (SD1, FC = 11H) is transmitted by the recorder in reply.
