I have to receive data via serial port from a device and I am using a FX5U with RS232 port.
The only baud rate which seems to work is 2400, which is very low in my opinion. I have tested the serial comm on the device with a PC, same cable and it works flawlessly at 57600 baud rate.
The FX5U and device serial settings are similar.
Any ideea what can cause the low speed?
