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.

A simple-to-install, user-friendly Web configuration software application enables programming through a browser connection. No time-consuming setup is required.

Set it up to operate in one of three modes:

In Direct IP Mode, you use TCP/IP or UDP/IP to communicate directly with the serial device.

In Virtual COM Mode, you can communicate with the device via your network just as if the device was connected to a physical COM port.

In Paired Mode, mUL®tiple serial devices can communicate with one another using network tunneling (more than one 1-Port Hardened Serial Server is required).

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 autodetecting 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.
