5.2.7 Software
update
With the Touch Control you can carry out an update of the instrument
program or load a new dialog language. The instrument program
(firmware) of the control device (Titrando, USB Sample Processor etc.)
can be updated with both the Touch Control and the PC Control.
The procedure for carrying out an update or a new installation of the PC
Control software is described in Section 2.1.2.
Note!
It is essential that the control software (Touch Control or PC Control) is
updated first and then the instrument program of the control device
(Titrando, USB Sample Processor etc.).
Touch Control and PC Control must always be updated at the same
time as the control devices.
