                  The networking module USR-TCP232-S2 is a brand-new, small-size serial-to-Ethernet module. This is a device that can realize direct data transmission between the network port and the TTL serial port. It can be applied to 232 and 485 interfaces through level conversion circuits.
                  The S2 module consumes less power and consumes less current at full speed. Equipped with M0 series 32-bit processor, it runs faster and more efficiently. At the same time, the module's diversified functions can better meet the needs of customers.
                  The S2 module is easy to operate and has strong compatibility. Compatible with the T24 series of setup protocols based on the addition of new features, providing convenience for older users. At the same time, it has added a setting protocol similar to M4. Customers who use other series of product setting protocols can apply to S2 with simple adjustment.


                  1. 10/100Mbps adaptive Ethernet interface, support AUTO-MDIX network cable cross-connect automatic switching
                  2. Working mode can choose TCP Server, TCP Client, UDP Client, UDP Server, HTTPD Client
                  3. The serial port baud rate can be set from 600bps to 460.8Kbps, supporting None, Odd, Even, Mark, and Space.
                  4. Customize the heartbeat package mechanism to ensure the connection is reliable and eliminate dead connections.
                  5. Customize the registration package mechanism to detect the connection status, or you can do a custom header.
                  6. In TCP Server mode, the number of connected clients can be arbitrarily set between 1 and 16. The default is 4. The IP of the connected client can be displayed, and the data is sent/received according to the connection.
                  7. Support webpage, AT com mand, serial protocol, network protocol setting parameters, provide setting protocol for customers to integrate into their own software.
                  8. DHCP function, can automatically obtain IP
                  9. The MAC address can be modified, and the factory only writes the global unique M A C.
                  10. DNS function, domain name resolution
                  11. DNS server address can be customized
                  12. It is more convenient to upgrade the firmware by upgrading the firmware function through the network.
                  13. Support virtual serial port, supporting USR-VCOM software developed by others
                  14. Support both software and hardware factory reset
                  15. Can run across gateways, switches, routers
                  16. Can work in LAN or access external network
