Communicate easily with an RS-232, RS-422, or RS-485 serial device via your LAN or WAN with the rugged and compact 1-port hardened serial server from Black Box.

It's just what you need to improve productivity and cut down on the amount of time required to configure or troubleshoot a serial device located on a factory floor or in a remote location.

Eliminate visits to a distant site just to make a minor change to a configuration. You can do all this from the comfort of your office using an Ethernet LAN or WAN connection, or even from home via a standard web connection.

The hardened serial server has a standard DB9 serial port and a removable terminal block for the RS-232, RS-422, or RS-485 device connection, and an auto detecting 10BASE-T/100BASE-TX port for a CAT5 connection to your Ethernet network.

Plus, for reliable operation, the serial server offers a heartbeat connection, which detects any TCP communication failures and sends out signals every five seconds until the system is reconnected.
