Overview
Both the Trio Q and Trio J radios have a multi-use serial port. Each radio features a 9 pin miniature D-Shell (DE-9) female connector that supports two individual serial port connections.
Typical use case for the J (unlicensed 900Mhz/2.4Ghz) or Q (licensed 150Mhz/450Mhz) radios will be Ethernet communications. Yet for legacy applications, a Modbus Gateway (Modbus TCP to RTU protocol converter), or Modbus Serial Device Server (Modbus RTU in TCP) may be configured on the serial port. A serial port may also be configured as a TUI (Text User Interface) for configuration/diagnostics. The TUI diagnostics is useful on systems suffering from high error rates as it provides a basic high speed interface.
Serial port configuration is accomplished with a web browser and the default IP address of both radios is 192.168.2.15. Details of how to configure each radio’s serial port for your application can be found in the Q or J radio documentation installed with TVew+.
