PUSR USR-TCP232-302 Tiny Size RS232 - Review

When it comes to device networking communication, the PUSR USR-TCP232-302 Tiny Size RS232 to TCP IP Converter Serial RS232 to Ethernet Server Module Ethernet Converter Support DHCP/DNS is a low-cost serial device server that is worth considering. Its main function is to provide a bidirectional transparent transmission between RS232 and Ethernet. This product is internally integrated with TCP/IP protocol, allowing the user to apply it to several device networking communication.

This device is relatively easy to set up as it supports DHCP, which automatically obtains an IP address. Additionally, users can query the IP address through serial setting protocol. It also supports DNS function, and users can set parameters through the device's webpage. The firmware can also be upgraded via network, which makes maintaining the converter easy.

The PUSR USR-TCP232-302 Tiny Size RS232 to TCP IP Converter Serial RS232 to Ethernet Server Module Ethernet Converter Support DHCP/DNS comes with an auto-MDI/MDIX, RJ45 port that supports 10/100Mbps. Its serial port baud rate ranges from 600 bps to 230.4 Kbps, and the check bit can either be None, Odd, Even, Mark, or Space. With its work mode as TCP Server, TCP Client, UDP Client, UDP Server, and HTTPD Client, the device is versatile and suitable for different purposes.

In addition, the PUSR USR-TCP232-302 Tiny Size RS232 to TCP IP Converter Serial RS232 to Ethernet Server Module Ethernet Converter Support DHCP/DNS also supports virtual serial port and provides corresponding software USR-VCOM. The heartbeat package mechanism ensures reliable connection and puts an end to dead links, while the user-defined registration package mechanism checks connection status and uses custom packet headers.

Under the TCP Server mode, the PUSR USR-TCP232-302 Tiny Size RS232 to TCP IP Converter Serial RS232 to Ethernet Server Module Ethernet Converter Support DHCP/DNS client number ranges from 1 to 16, with a default number of 4. The global unique MAC address, which is bought from IEEE, is also included. The user can define their MAC address.
