*Only one RS232 port is available when the SDI-12 interface is enabled.

The transceiver is configured via a USB interface and compatible Virtual COM Port (VCP) driver. One VCP is
created for the transceiver configuration interface and a second VCP for the extended sensor interface
configuration port (if the extended sensor interface is present). A USB configuration cable is available from
SRT.
All configuration is performed via the USB VCP using the standardised and proprietary IEC61162 sentences
defined in section 10.2.
