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:

1. In Direct IP Mode, you use TCP/IP or UDP/IP to communicate directly with the serial device.
2. In Virtual COM Mode, you can communicate with the device via your network just as if the device was connected to a physical COM ports.
3. In Paired Mode, multiple serial devices can communicate with one another using network tunneling.

The LES421A Hardened Serial Server has two standard DB9 serial ports for the RS-232, RS-422, or RS-485 device connections, 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.
