USR-TCP232-302 RS232 to TCP/IP Module Ethernet Converter Support DHCP/Web page Introduction This is a serial RS232 to Ethernet server,used for data transparent transmission.USR-TCP232-302 is a low-cost serial device server,whose function is to realize bidirectional transparent transmission between RS232 and Ethernet. USR-TCP232-302 is internally integrated with TCP/IP protocol.User can apply it to device networking communication. Features Support DHCP, automatically obtain an IP address and query IP address through serial setting protocol Support DNS function Set parameters through webpage Upgrade firmware via network Auto-MDI/MDIX, RJ45 port with 10/100Mbps Serial port baud rate from 600 bps to 230.4 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 Support customization Parameter Voltage: DC 4.75 ~ 7V Current : 150mA Size: 71 x 60 x 25 mm Operating Temp: -25 ~ 75°C Storage Temp: -40 ~ 105°C, 5 ~ 95% RH Interface: RS232 Network Protocol: IP, TCP, UDP, DHCP, DNS, HTTP, ARP, ICMP _x000D_
