Usr-tcp232-test [work] Jun 2026
usr-tcp232-test usr-tcp232-test is a dedicated validation and diagnostics utility for USR-TCP232 series devices (such as the USR-TCP232-302, 304, 306, and 410S). Its primary purpose is to verify the correct operation of serial-to-Ethernet conversion, focusing on data integrity, baud rate accuracy, and TCP/UDP communication stability. Key Test Areas
Loopback Test Sends configurable data patterns (e.g., incrementing bytes, random payloads, or fixed ASCII strings) from a TCP client to the device’s serial port, then reads back the data through the same or a complementary channel to detect corruption, duplication, or data loss.
Baud Rate & Framing Verification Iterates through standard baud rates (2400 to 921600) with various parity, data bits, and stop bit combinations to ensure the USR-TCP232 module correctly negotiates and maintains serial parameters under load.
Throughput & Latency Measurement 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. usr-tcp232-test
Multi-Connection Stress Simulates up to 16 simultaneous TCP clients or UDP streams to validate the device’s concurrent session handling, queue management, and response under peak load.
Execution Environment
Host OS : Linux (Ubuntu 20.04+), Windows 10/11, or any POSIX-compliant system with Python 3.8+. Dependencies : socket , pyserial , argparse , time , threading (standard library plus PySerial for serial control). Device Under Test : USR-TCP232-x02/x04/x06 series, configured in TCP server, TCP client, or UDP mode with known IP/port. Execution Environment Host OS : Linux (Ubuntu 20
Example Command python usr_tcp232_test.py --device /dev/ttyUSB0 --baud 115200 --target 192.168.1.200:8899 --mode tcp_client --pattern random --duration 60
Expected Output A successful test run produces a summary like: [INFO] Starting USR-TCP232 loopback test (TCP client mode) [TEST] Pattern: random, packet size: 1024 bytes, 10 packets/sec [PASS] 1000 packets sent, 1000 received, 0 errors, 0 lost [LATENCY] Avg RTT: 2.3 ms, Max RTT: 5.1 ms, Jitter: 0.4 ms [RESULT] All test criteria PASSED.
Failure Handling Any mismatch in echoed data, timeout, or checksum error triggers a detailed error log with hexdump of the first failing packet and the device’s current configuration. The test tool exits with non‑zero code for CI/CD integration. Some of its key features include:
