We have configured USB COM port at 625000 baud rate and reading the data continously. When the COM port is read for long time, see some garbage bytes inbetween valid data. Could somebody help what could be the problem?
Most of the time value 00 gets inbetween. This garbage value comes one are twice.
After reading the COM port for more than 1 hr this problem happens.
Labview tool runs on windows XP.
The connection from hardware to PC is as below.
1. From hardware RJ45 connects to RS232 connector.
2. Then RS232 cable connects to RS232- USB convertor.
3. The RS232-USB convertor is connected to PC as virtual COM port.
No electric motors or such kind in between. The wire could be nearly 1m long.
