          Ordering Information

          Communicate easily with four serial devices via your LAN or WAN with the rugged 4-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 serial devices 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.

          The 4-Port Hardened Serial Server has four standard DB9 serial ports for the device connections. Each serial port is software selectable for RS-232, RS-422, or RS-485 (2- or 4-wire) operation.

          For the network interface, the serial server has an autodetecting 10BASE-T/100BASE-TX port for a CAT5 connection to your Ethernet network, as well as an Ethernet passthrough port. The passthrough enables the serial server to also work as an Ethernet switch, so you can connect a local workstation, a second serial server, or other device to your network.

          Plus, for reliable operation, the 4-Port Hardened Serial Server offers a heartbeat connection, which detects any TCP communication failures and sends out signals every five seconds until the system is reconnected.
