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.
