3 Operation via RS232 Interface
3.1 General rules
The Titrino has an extensive remote control facility that allows full control of
the Titrino via the RS 232 interface, i.e. the Titrino can receive data from an
external controller or send data to an external controller. C
R
and L
F
are used
as terminators for the data transfer. The Titrino sends 2xC
R
and L
F
as termi-
nation of a data block,
to differentiate between a data line which has C
R
and
L
F
as terminators. The controller terminates its commands with C
R
and L
F
. If
more than one command per line is sent by the controller, ";" is used as a
separator between the individual commands.
The data are grouped logically and easy to understand. Thus e.g., for the se-
lection of the dialog language, the following must be sent
&Config.Aux.Language "english"
whereby it is sufficient to only transmit the boldface characters, thus:
&C.A.L "english"
The quantities of the commands above are:
Config configuration data
Aux auxiliaries, various data
Language setting the dialog language
The data are hierarchically structured (tree form). The quantities that occur in
this tree are called objects in the following. The dialog language is an object
which can be called up with the
&Config.Aux.Language
command.
If one is in the desired location in the tree, the value of the object can be que-
ried.
&Config.Aux.Language $Q Q means Query
The query command $Q initiates the issuing of the value on the instrument
and the value emission is triggered. Entries which start with $, trigger some-
thing. They are thus called triggers.
Values of objects can not only be queried, they can also be modified. Values
are always entered in quotes, for example:
&Config.Aux.Language "english"
