6.1.2.3 Configuring the Starflow RS232/UPS
Select the
RS232
tab.
The
RS232 Timeout
controls how long the logger will remain powered on and ready to
communicate at each scan interval. The factory default for most loggers is 1 second, which is
adequate for direct serial cable connections. However, if communications is to take place via a
modem, then this should be extended to 3-5 seconds (or more, as required). Longer timeouts will
lead to increased power consumption while the logger is communicating.
The
Scan Synchronous Communications
checkbox fine-tunes when the logger checks for a
computer attempting to communicate with it. When this checkbox is ticked, the logger will wait until
the end of a scan before checking to see if there is a computer wanting to communicate with it.
When this checkbox is not ticked, the logger does not wait. After this first check, the logger will
only check that the computer is still connected at the end of each scan, regardless of the setting of
this checkbox. For quick scan rates, this setting does not do much, however, for slower scan
rates, clearing this checkbox (to select asynchronous communication) may improve the logger’s
responsiveness to communications.
