3. Set-up Menu
The SC105 has a built-in set-up menu for configuring communication mode,
CS I/O port configuration, RS-232 port configuration, and other parameters.
The Set-up Menu is shown in FIGURE
. It is accessed by connecting the
SC105’s RS-232 port to a PC with the included null modem cable. The SC105
also needs to have power. Usually, the SC105 is powered by connecting the
SC105’s CS I/O port to the CS I/O port of a data logger.
With the null modem connection to the PC, typically Campbell Scientific’s
Device Configuration Utility
(
DevConfig
) is used, but a terminal program such
as
HyperTerminal
TM
or
Procomm
TM
(always 9600 baud, 8-N-1) can also be
used. Press the
Program
button on the SC105 for one second to access the Set-
up Menu. Changed settings are saved in flash memory by selecting
Apply
in
DevConfig or menu item

if using HyperTerminal or Procomm. If left idle,
the Set-up Menu will time out 60 seconds after the last received character and
exit without saving any parameter changes with the message “Set-up Timeout.”
A data logger can remain connected to the CS I/O port (to provide power to
