About the FloSI card
Once a remote device has been wired to the FloSI card it must be configured using software so that
the XCi device can provide access to it’s measurement results.
Serial interface settings
The FloSI can only be configured to use one serial protocol from the three available. The parameter values
are provided in the user configured units.
RS-232, ASCII mode
The line transmission characteristics are as follows:
l
Baud rate: 9600
l
Data bits: 8
l
Parity: None
l
Stop bits: 1
In this mode, the FloSI is dormant while RTS is inactive. On RTS going active, the FloSI transmits the most
current result string from the XCi device. If RTS is active when a scheduled sample is made, then the string is
transmitted immediately on completion of the measurement. The transmitted ASCII text string starts with
the character ‘
*
‘(asterisk), ends with a carriage return and contains the configured number of channel values.
The number and order of channel values in the output string can be configured using Each channel
value in the string always begins with either a ‘
+
’ (plus sign) or ‘
-
‘ (minus sign) - there are no spaces between
values.
SDI-12 mode
The SDI-12 implementation complies with V1.3 of the SDI-12 specification.
Configurable parameters are:
l
Address (‘0’-‘9’, ‘A’-‘Z’, ‘a’-‘z’)
l
Which measurement results to provide
On receiving an SDI-12 Measurement command, the FloSI replies with notification that the measurement
results are immediately available. Upon receiving a Send Data command, the FloSI returns the currently
available result data which it has been configured to provide.
