Different serial A-D devices usually have different communication speeds (baud rates), and these have to be matched by LabHelper in order for communication to function. When you specify a particular A-D converter, LabHelper will select what it thinks is the correct baud rate. However, with most devices you can adjust that rate if necessary.
The default baud rates are as follows:
| Sable Systems UI3: | 115.2 Kbaud (no adjustment possible)
| | Sable Systems UI2: | 115.2 Kbaud
| | DataTaker DT800: | 57.6 Kbaud
| | DataTaker DT500, DT600: | 4800 baud
| | DataTaker DT50: | 9600 baud
| | Advantech ADAM: | 9600 baud
| | Streaming serial devices: | 9600 baud
|
Note that some A-D devices require setting baud rates with jumpers or DIP switches, but most modern ones respond to software commands. LabHelper will attempt to set such devices to the highest feasible rate.
