Usr-tcp232-test [LATEST]

Generates sustained traffic (e.g., 1 kB to 64 kB packets at 10–1000 Hz) to measure round-trip time (RTT), jitter, and maximum sustainable data rate without buffer overflow or TCP retransmission.

If you have ever worked with a USR IOT (or USR) serial to Ethernet converter—such as the popular USR-TCP232-302, USR-TCP232-304, or USR-TCP232-306 modules—you have likely encountered this software utility. The usr-tcp232-test tool is the official configuration and testing software provided by the manufacturer to simplify the setup, debugging, and data transmission testing of these serial device servers.
