The EX9531 is an intelligent, stackable expansion module that connects to a PC USB port or USB hub, providing one High-Speed RS422 or RS485 serial port (jumperless). The EX9531 provides easy connectivity for traditional serial devices.
The RS422 supports full-duplex communication and handshaking signals (such as RTS, CTS). The RS485 control is completely transparent to the user, and software written for half-duplex COM works without any modification.
The EX-9531's opto-isolators provide 3000V DC of isolation to protect the host computer from ground loops and destructive voltage spikes on the RS422/485 data lines.
EX-9531 also offers internal surge-protection on the data lines. Internal high-speed transient suppressors on each data line protects the module from dangerous voltage levels or spikes.
The module derives power from the USB port, so it doesn't need an external power adapter.
