6.2 Configuring computer
This section describes setting up communications using a terminal emulator program. The
terminal emulators built into many Campbell Scientific software products such as
LoggerNet
can
also be used.
The following settings should then be used by default:
Bits per second: 38400
Data bits: 8
Parity: none
Stop bits: 1 Flow control: none
NOTE:
After adjusting the baud rate of the unit, use the terminal emulator to adjust the bits per
second value in the port settings. The CS140 can not communicate with the computer if the
unit and port setting baud rates differ.
The
CS140
should
now
be
ready
to
accept
commands.
