9600 (Most common for RoHS 721, though some models require 4800 or 19200). Data Bits: 8 Parity: None Stop Bits: 1 Flow Control: Hardware or Xon/Xoff. Troubleshooting Common Connection Issues
Plug the USB cable into a on your PC (avoid blue USB 3.0 or Type-C ports if possible, as legacy chips occasionally conflict with newer USB controllers). Connect the other end to the cutter. Turn the RoHS 721 power switch to ON . Step 4: Verify in Device Manager
