General Information

The menu only ever shows functions that are available for the
current constant temperature equipment.
The menu for configuring the interface is integrated in the main menu of the
relevant constant temperature equipment:
Menu  Modules  Serial interface

Interface functions such as read and write commands make it possible to
read out the current operating parameters of constant temperature equip-
ment and predefine specific settings and process values.
The interface functions supported by this interface are presented briefly
below. They are sorted by topic according to the component affected and
assigned a unique ID. Depending on the technical configuration of your
constant temperature equipment, the number and scope of the interface
functions actually available may vary from the list shown here, see chapter
"Availability of the interface functions".
Communication takes place according to the master/slave principle. In order
to ensure that a request and response are uniquely assigned to one another,
commands can only be sent to the constant temperature equipment once a
response to the previous command has been received.
All available read and write commands as well as the meaning of any error
messages that may occur are presented below. Note the following informa-
tion relating to syntax and sequencing when using these commands:
