The ELK-ESS4202 Ethernet to serial server is the easiest way to connect RS-422 or RS-485 serial devices to your Ethernet network. These products use industry standard RFC 2217 TCP/IP protocol for maximizing compatibility with the widest range of applications and devices. The software drivers and utilities make installation and operation easy using Windows 98SE, 2000, XP and Vista operating systems. After software installation, the ELK-ESS4202's serial ports appear as virtual COM ports to the host machine. Standard serial operating calls are transparently redirected to the ELK-ESS4202, guaranteeing compatibility with legacy serial devices and enabling backward compatibility with existing software. Serial tunneling is also supported, allowing two native serial devices to communicate over a network. Alternatively, raw data socket mode is supported, eliminating the need for a driver.
