1-port RS 232/485/422 Serial to Ethernet Gateway

NP311 is a serial device server which can connect with network fast. It provides one RS-232/485/422 (RS-232: dB9M; RS-484/422: 4 bits terminal block) and 1 10Base-T Ethernet port, it can manage the disperse serial device or host computer by network, easily and convenience. Setting or software upgrade by serial program group in apply, support TCP, UDP, ARP, ICM and DHCP protocol, support Windows Native COM and auto-connect function once the network intermit.
In addition, NP311 provide the management collocate tools that based Windows flat roof. It can lead the user manage and configure facility step by step, all of the setting can be done by network or serial. Support pass gateway and router, easily for user to set IP address, Server and Client mode, size of data and so on, Can realize the serial device connect with network by simply setting.
Its outside design support DIN-Rail and Wall mounting, apply to project easily.
