Chapter 2 Configuration
The
GSI or RS-232 channel
uses a serial communications interface used by the data logger to
retrieve data from devices such as analyzers and digital control systems. The interface can
receive data strings and stores values into GSI Channels for data collection. For these channel
types, the “Misc” screen allows the user to define which RS-232 port is to be used, the type of
instrument being connected, and the value within that instrument that is desired. Note that the
baud rate of the RS-232 port is set in the PC Settings editor.
On the Misc tab an option is given for Hold Data Between Updates? is set to Yes or No.
If Yes is selected it will use the last value received until the next value arrives, for instruments
that send data infrequently. Normally, this is set to “No.”
