This is a Ethernet RS232 Converters serial RS232, RS485 or RS422 to Ethernet server, used for data transparent transmission. USR-TCP232-306 is a low-cost serial device server, whose function is to realize bidirectional transparent transmission between RS232, RS485 or RS422 and Ethernet. USR-TCP232-306 is internally integrated with TCP/IP protocol. User can apply it to device networking communication.

Features of Serial RS232 RS485 RS422 Ethernet converter

• Auto-MDI/MDIX, RJ45 port with 10/100Mbps

• Work mode: TCP Server, TCP Client, UDP Client, UDP Server, HTTPD Client

• Baud rate of serial port can be configured from 600 bps to 230.4 Kbps, supports check bit of none, odd, even, mark and space

• 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

• Supports RS232/RS485/RS422 port ( Can’t be used at one time)

• Under TCP Server Mode, the connection number with client can be randomly set from 1 to 16, default number is 4. IP has been connected can be shown according to connectiong with calculating send / recceive dat.

• When connection number reaches a maximun, the new connection is kicked off the old one can be configured by user

• Parameters can be configured by built-in webpage, AT command, serial port procotol and network procotol. Setting procotol is avaliable to integrate into user’s software.

• Supports TCP client short connection function, user-defined the disconnected time.

• Device restart if no data transmission or timeout. User-defined the restart time.

• If data buffer needs to clear configuration before TCP connection establishment

• Supports DHCP, automatically obtain an IP address and query IP address via serial setting protocol.

• The global unique MAC address, user-defined MAC address

• DNS function

• DNS server addres can be defined

• Firmware can be upgraded by network

• Provide Virtual com software

• Restore factory setting through software or hardware

• Running across the gateway, switches or routers.

• Can work in LAN, also can work in the Internet

•
