Usage Tips:USR-TCP232-T2 is a tiny size serial Ethernet module which can realize data bidirectional transparent transmission between TTL and RJ45 Port. It can also be applied in RS232/ RS485 by level shift circuit. USR-TCP232-T2 is based on Cortex-M0 core. It has characters of low power, fast speed and high efficiency. Support DHCP, automatically obtain an IP address and query IP address through serial setting protocol Support DNS function Set parameters through webpage and serial AT command Upgrade firmware via network Auto-MDI/MDIX, RJ45 port with 10/100Mbps Serial port baud rate from 600 bps to 460.8 Kbps, Check bit of None,Odd,Even,Mark and Space Work mode: TCP Server, TCP Client, UDP Client, UDP Server, HTTPD Client Support virtual serial port and provide corresponding software USR-VCOM Heartbeat package mechanism to ensure connection is reliable, put an end to dead link User-defined registration package mechanism, check connection status and use as custom packet header Under TCP Server mode, Client number ranges from 1 to 16; default number is 4 The global unique MAC address bought from IEEE, user can define MAC address Restore factory default Across the gateway, switches, routers Can work in LAN, also can work in the Internet (external network) Provide PC TCP/IP socket programming example such as VB,C++,Delphi,Android and IOS Colour:As Shown Material:PC style:T2 Old / T2-E8 Due to different batches, there may be differences in product appearance and printed text, which will not affect use Package Contents: 1 * Modules Only the above package content, other products are not included.
