For additional details on the passthrough functionality and configuration, see
-Serial Passthrough Application Guide listed in Additional information.
The procedures in these sections assume that the COM ports are wired correctly.
4.8.1 Configure the XIO
This procedure configures the XIO Ethernet port to act as a passthrough for the specified serial port. It
also configures the serial port for communication with the attached peripheral.
The serial port on the XIO can connect external devices such as XMVs and other transmitters while the
corresponding interface application (for example, XMV Interface) runs on the RMC.
Use any of the serial (COM) ports on the XIO to connect with any external serial device, such as radios
and measurement transmitters. This scenario shows a single ABB multivariable transmitter (XMV)
connected to the XIO. Other scenarios might include multiple XMVs on the same COM port.
To configure Ethernet-Serial passthrough for an XIO COM port:
