ESL 8 port RS-232 RJ45


Eight Ethernet-to-serial remote port

Ideal for POS systems, security systems, industrial automation, building automation, or any application using RS-232 devices, LAVA Ether-Serial Links provide serial ports that are network-enabled and simple to install, configure, and control.

Any serial device can send its information to an Ether-Serial Link, which then places that information on the Ethernet.

The serial ports of the LAVA Ether-Serial RS-232 8-RJ-45 look and act precisely like they are built into your computer: they appear right alongside other serial ports in Windows’ Device Manager.
