  • The 4403 Ethernet to serial server is the easiest way to connect RS-232, RS-422, or RS-485 serial devices to your Ethernet network. SeaLINKŪ 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 Microsoft Windows operating systems. After software installation, the 4403's serial ports appear as virtual COM ports to the host machine. Standard serial operating calls are transparently redirected to the 4403, 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.
