Serial RS232 RS485 RS422 Ethernet converter: USR-TCP232-306 is a multi serial port ethernet converter,which can realize bi-directional transparent transmission between RS232/RS485/RS422 and Ethernet. User can directly process data interaction through network and device to realize remote data acquisition, remote control and management. 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 ( Canot 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 users 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 Application Field of Serial RS232 RS485 RS422 Ethernet Converter Industrial data transmission, industrial automation security and protection monitoring, public security Smart home, power control, environmental monitoring, intelligent agriculture Door check on work attendance system, POS system, rice selling system Building automation system, power monitoring, self-service banking system, telecom machine room monitoring
