Hi,
I have a RUT956 device and I have used the USB port to read data from a sensor sending ASCII strings via a RS232 to USB FTDI device.
So the setup is: RS232 sensor → FTDI chip → RUT956 USB port.
I have made some code in the Teltonika Busybox to interpret and send the data. This works great.
Then, I have replaced the FTDI chip with USB hub and to the hum I have connected a USB stick for storage expansion and the FTDI chip. This still seems to work fine.
I was wondering if I can plug more FTDI chips to the USB hub. Is there a limit, or I could potentially read data from 4-5 sensors via FTDI chips, connected to the hub?
Thank you,
Alberto
