This RS-232 To Ethernet TCP/IP Adapter allows any of the RS232 serial ports on our switchers that have an RS-232 interface to interface directly to a Ethernet TCP/IP network.

We are providing new ways of connecting serial devices to a Local Area Network (LAN) or Wide Area Network (WAN). EP-132 TCP/IP converter is designed to operate serial ports over 10/100M Ethernet networks. The data is transmitted via TCP/IP protocol. Therefore control is available via Ethernet, Intranet and Internet. EP132 TCP/IP converter is packaged in a plastic case well suited for industrial environments.

All serial ports operate in common RS-232 mode, industrial RS-422 and RS-485 modes configuration. EP132 TCP/IP converter series is a low-cost, high performance design. By careful selecting high quality with competitive prices components in the world, EP132 makes network connectivity possible with affordable cost for virtually all kinds of serial devices.

This RS-232 To Ethernet TCP/IP Adapter is the best choice for transmitting serial data across an IP network and offers flexibility, high performance and advanced RS232 to Ethernet adapter technology

This Ethernet to Serial converter adds Ethernet ability to any of our switchers that has an RS-232 port. Simple and quick installation with auto-detect feature. Works with WINXP and WIN2000. Includes redirect software that maps any local COM port to an IP address you assign to the device. Works with our routing switcher program or yours.
