whereas the low state close a connection. Allow TCP connection only by HIGH is valid only if host
mode is TCP server or equivalent. If this option is set, the incoming TCP connection request will be
accepted only when the DSR signal is high state.

4.3 Cryptography configuration
The HelloDevice Pro Series supports encrypted sessions for only TCP modes including modem
emulation mode (not UDP mode). By setting the cryptography method as 3DES, the HelloDevice Pro
Series can communicate with other HelloDevice Pro Series in encrypted sessions. If you need your
PC to communicate with HelloDevice Pro Series using encryption, please contact Sena technical
support.
