Absolute must have for communication debugging.
Review by
Pinegirl
Works great for debugging PLC communication issues. I was chasing a ghost issue on an integrated PLC for a stationary battery backup system and this device showed exactly why the issue was happening. My com link cable had a broken wire at one end and this device instantly showed the result of it and finally put the ghost to rest after a quick cable swap.

Have been testing different USB-RS232 adapters to work with some old legacy radio programing applications, this adapter is the most compatible yet.
