  # To capture communications for debugging / analysis
  # Use Wireshark with https://github.com/Omniflux/fujitsu-airstage-h-dissector
#  tzsp:
#    ip: 192.168.1.20
#    protocol: 255

Configure TZSP and use Wireshark with fujitsu-airstage-h-dissector to debug / decode the Fujitsu serial protocol.
