RS232/422/485 Serial Over Ethernet Converters

Ethernet to serial converter allows large quantities of knowledge to become transferred through each serial port coupled with a quick Ethernet connection. The elevated control and automation of serial over ethernet converter, through your existing network infrastructure, can help you reduce your costs and improve efficiency, yet smart enough for just about any office environment.

Key Features Of Ethernet To Serial Converter:
Cable replacement using serial-Ethernet;
Have virtual COM ports connect PC/servers to remote serial devices over Ethernet;
Communicate to multiple serial devices at the same time across a network;
Use serial-Ethernet to exchange existing serial dial-up modem connections;
Manage the serial console port on remote equipment (Servers, routers, switches, etc) over Ethernet or through of band connections;
Use serial-Ethernet to connect serial PLCs to Ethernet;
Connect serial signage equipment over Ethernet with serial-Ethernet adapters.

All serial converters feature a minimum of an Ethernet port and software-selectable RS232/422/485 serial interfaces, and meet IEC safety (IEC 60950-1) and EMC (EN 61000) standards. They support various protocols for serial data transmission including Modbus/TCP, raw serial data over UTP, IPv4 and IPv6. The 4 and 8 port RS422/485 devices, as with the rest of the range, will enable connection across a network with no loss of reliability or signal integrity. The Port3 connector signal level is of RS485 or RS232. This port could be stated as a general CPU module communication port and useful for peripheral applications.

One of the leading differences between RS232 Modem and RS422/RS485 is the signaling mode. RS232 is unbalanced while RS422/RS485 is balanced. An unbalanced signal is presented by a single signal wire in which a voltage level on that one wire can be used to transmit/receive binary 1 and 0: it can be considered a push signal driver. On the other hand, a balanced signal is presented by a set of wires where a voltage difference can be used to transmit/receive binary information: kind of a push-pull signal driver. In a nutshell, unbalanced voltage level signal travels slower and shorter than the usual balanced voltage difference signal.

RS485 converter may also be termed as RS485 Multidrop LAN because it can connect several devices in a LAN network environment. These devices are linked to a single pair wire. Transmit and receive share the same two wires.

Serial to LAN bridge mode allowing transparent bridging of serial devices over LAN, while using 3 Mbps fast UART. Full Internet controller mode allows a simple microcontroller to use the module's protocol and application capabilities to do complex Internet operations for example e-mail, FTP, SSL, embedded web server and others. It also provides a firewall, providing a security gap between your application and the network. PPP modem emulation mode allows existing modem designs currently using PPP to connect transparently over LAN.

With robust metal housings and fanless cooling, the converters are claimed to provide benefits and features to match applications such as discrete manufacturing, processing operations, power generation and distribution, and building automation. Fiberstore is a leader manufacturer in serial connectivity, has introduced RS422 converter/ RS485 converter versions of their 4 and eight port Ethernet to serial products. As with all our Ethernet to Serial port devices, these new products are made to provide easy, fast and reliable connections between networked computers and devices with serial ports- be it across the desk or around the globe.
