communicate a prompt box will be generated requesting to use “demonstration mode” or a re-
test.
Most commonly communications problems occur because the control unit is not switched on or set
to “PC-mode”. However if anything other than COMM 1 is being used, the command line for the
program will need to be changed. This is done by closing the program, selecting the appropriate
icon with a right mouse click and select Properties from the menu. The command line will need to
be changed from:
C:\Program Files\Hansatech Instruments\FMS\Modfl32.exe
to:
C:\Program Files\Hansatech Instruments\FMS\Modfl32.exe /x
(where x is the port number that the FMS is connected to. Please note that the space between the
modfl32.exe and /x is required)
The program should then be re-started.
Please note that the process described above is also true of Parview.
3.1.3
Troubleshooting Communications Problems
The default communications between the PC and the FMS are set through COMM 1 at 38,400 baud
rate. Some older serial port chip-sets may not be able to cope with this speed of data transfer,
resulting in communications problems or file uploading problems.
The following procedure should be followed to troubleshoot such communications issues:
1. Check the serial cable connection to both the PC and the FMS control unit.
2. Check that the /x is entered into the command line if anything other than COMM 1 is being
used (
Executing Modfluor and Parview
.).
3. Adjust the baud setting of the FMS control unit. This is achieved by switching off the control unit
and keeping the lower control key on the display panel de-pressed whilst it is switched on. As the
instrument boots-up a menu will display the new baud setting of 19,200 baud. The procedure may
be repeated to switch to 9,600 baud or repeated again to loop forward to 38,400 baud.
4. Once a baud rate has been selected it will be retained in memory by the control unit and used
each time the instrument is switched on.
5. The “Modfluor” and “Parview” software should be re-booted if the baud setting is changed.
Both programs automatically detect, and switch to the appropriate baud setting during
initialisation.
Use of a slower communications rate will not impair the real-time data acquisition performance of
