SeaLINK USB Serial AdaptersWhether you require one serial port or sixteen, SeaLINK(r) USB serial adapters will have you quickly communicating with RS-232, RS-422, and RS-485 peripherals. Unlike traditional UART-based products, SEALINK USB serial adapters use a state-machine architecture that reduces host processor overhead for faster, more reliable communications.View More Products | SeaLINK Ethernet Serial ServersSeaLINK(r) Ethernet serial servers offer the easiest way to connect RS-232, RS-422, and RS-485 serial devices to your Ethernet network. All SeaLINK devices use industry standard TCP/IP protocol enabling any host to access serial ports as virtual COM ports. Designed using a powerful embedded microprocessor, SeaLINK products are able to communicate over multiple ports at sustained data rates up to 230K bps.View More Products | PCI Express Serial BoardsSealevel PCI Express serial boards are designed for computers with X1 PCI Express slots, and are fully compatible with X2, X4, X8, X16, and X32 PCI Express slots. The boards utilize serial UARTs with 128-byte FIFOs for maximum reliability in data intensive applications. Software for standard PCI boards will also work with PCI Express boards, simplifying your transition to this next-generation PCI bus.View More Products |
PCI Serial BoardsSealevel's PCI bus serial boards offer the widest choice of I/O connectivity available. Products include RS-232, RS-422 and RS-485 solutions.

Ordering options allow the choice of UARTs with larger FIFOs, support for custom baud rates, and 9-bit protocols. Robust software drivers make installation easy.View More Products |
Serial Interface ConvertersSealevel serial interface converters allow a standard RS-232 port to communicate with an individual RS-422 device or multiple RS-485 devices. Full duplex and half duplex modes are supported. Optically isolated versions are available providing immunity from ground loops and surges. Sealevel serial interface converters are available in extended temperature versions and OEM versions without enclosures.View More Products | Compact PCI Serial BoardsSealevel 3U Compact PCI boards are available with RS-232, RS-422, and RS-485 serial interfaces. An optically isolated multi-interface version protects the host backplane from ground loops and transient voltages common in industrial environments. Sealevel Compact PCI serial boards are available in extended temperature versions.View More Products | ISA Serial BoardsSealevel continues to provide a full line of ISA serial and digital I/O products to support legacy applications. All of our quality products come with a Lifetime Warranty that guarantees the performance of our components over the life of the product.View More Products |
