The 4203 Ethernet to serial server is the easiest way to connect RS-232, RS-422, or RS-485 serial devices to your Ethernet network. SeaLINK products use industry standard RFC 2217 TCP/IP protocol for maximizing compatibility with the widest range of applications and devices.
Sealevel's SeaLINK software drivers and utilities make installation and operation easy using Windows 98SE, 2000, XP and Vista operating systems. After software installation, the 4203's serial ports appear as virtual COM ports to the host machine. Standard serial operating calls are transparently redirected to the 4203, 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. Each port can be individually configured as RS-232, RS-422, or RS-485.
To simplify installation and configuration, a printed copy of the SeaLINK QuickStart Guide is included with all Ethernet serial server orders.
