What are LAVA Ether-Serial Links?

Ether-Serial Links are network devices that install serial ports on Ethernet networks. The serial ports in an Ether-Serial Link send information to an Ethernet, by converting it to an IP-compatible format and sending it out the Ethernet side of the Ether-Serial Link. Data moving the other direction, from the Ethernet side of the Ether-Serial Link to the serial device, undergoes the same process in reverse.

Ether-Serial Links are among the most versatile of network devices. With them, you can access and control serial ports across a network, as simply and easily as if they were right in the box of the PC beside you. You can extend a serial connection to any distance, even across the Internet.

Ether-Serial Links assign IP addresses to their serial ports, making it possible for a single PC to control many serial devices, or for many PCs to access a particular serial device. The ports of a Lava Ether-Serial Link are conventional serial and Ethernet ports.

Extend the reach of serial ports, without a network

An Ether-Serial Link can be connected directly to a PC’s network interface card using an Ethernet crossover cable. In this configuration, a one-to-one relationship exists between the Ether-Serial Link and a PC. The serial ports of the PC have the serial ports of the Ether-Serial Link added just as if they were in the PC itself. The 50 foot cable limitation of RS-232 no longer exists!

Access and control a serial device across a network

Here’s where things get interesting. An Ether-Serial Link makes it possible to attach a serial device anywhere on a LAN or WAN. Simply attach the serial device you wish to network-enable onto an Ether-Serial Link, and connect the Ether-Serial Link to a network switch or hub. Install the Ether-Serial Link driver on any system that you want to use to access the Ether-Serial Link’s ports. This driver installs the Lava Discovery Protocol, which can automatically detect and access Ether-Serial Links on the same network segment. Supply a gateway address, and Ether-Serial Links can be made available to the LAN or WAN as a whole, across switches or routers. Access to the Ether-Serial Link’s serial ports can be restricted to specific network users, or open to the network as a whole. Whatever a PC could do through its internal serial ports? controlling factory equipment, operating POS devices, or monitoring a security system, for example?can now be done transparently across a network.

Access and control a serial device across the Internet

The power of the serial networking really shows when it is used to tap the infrastructure of the Internet or a company intranet. In this application, Ether-Serial Links are configured with both IP and gateway addresses, and become available anywhere the Internet reaches. Now that’s power! Connect Simply.
