Incorrect PC/LIMS configuration at Touch Control
Check whether the communication mode on the Touch Control
has been set to “Ext. system access” under System / Device
manager / PC/LIMS [Edit], and that the selected RS 232 interface
is the same as that which is actually being used. After a configu-
ration alteration the Touch Control must be restarted.
Touch Control has been started before the 825 Lab Link
Server program
Start the Touch Control only after the 825 Lab Link Server has
been started.
