Dual Port USB-to-Serial Sniffer

Rated 5.00 out of 5 based on 1 customer rating
(1 customer review)


The dual port serial sniffer is an integrated, ultraconvenient way to inspect UART lines in an embedded system. The device offers two channels for Tx/Rx communication directly to MCUs or UARTcable modules. Having two ports allows just the receivers to be used to unobtrusively attach to Tx and Rx lines on the target to monitor traffic. Reliable FTDI drivers facilitate simple connection to terminal programs in Windows, MAC and Linux operating systems. Each channel will appear as a separate COM port and can thus be individually configured for different data rates and monitored and/or logged in separate terminal windows. Target hardware requires only test points for access, and any custom connectors can easily be attached to the available headers.

    What a lifesaver. I have given away my home-made sniffers. I’m sure the two separate USB ports will come in handy some day.
