Serial I/O
Sealevel asynchronous and synchronous serial interfaces are designed for high-speed applications and support RS-232, RS-422, RS-485, and RS-530 electrical interface standards. Whether you choose a traditional bus-based approach or opt for easy-to-use USB or Ethernet solutions, you will be quickly communicating with your serial devices. Every product ships with thorough software drivers and useful tools to make setup and installation a snap.
USB Serial Adapters
Whether you require one serial port or sixteen, SeaLINK® 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.
Ethernet Serial Servers
SeaLINK® 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 230Kbps.
PCIe Asynchronous Serial Adapters
Sealevel PCI Express X1 serial boards are fully compatible with X2, X4, X8, X16, and X32 PCI Express slots. The boards utilize serial UAERS with 128-byte FIFOs for maximum reliability in data-intensive applications. Software developed for standard PCI boards will also work with Sealevel PCI Express boards, simplifying your transition to this next-generation PCI bus.
PCI Asynchronous Serial Adapters
Sealevel's PCI bus serial boards offer the widest choice of I/O connectivity available. Products include RS-232, RS-422, and RS-485 solutions. Our PCI boards are available with a wide range of accessories to make installation easy. Sealevel low profile Universal Bus PCI boards are designed for many newer computers that lack standard height PCI slots.
PCI Synchronous Serial Adapters
Critical military, aerospace and commercial applications often use synchronous communication when high-speed data transfer is required. All Sealevel synchronous serial products are engineered with strict attention to timing to achieve the most reliable, high-speed communication possible. Choose from a variety of RS-232/422/485 multi-interface products that support HDLC/SDLC and other protocols.
PCIe Synchronous Serial Adapters
Sealevel PCI Express X1 synchronous serial boards are fully compatible with X2, X4, X8, X16, and X32 PCI Express slots. Software developed for standard PCI adapters will also work with Sealevel PCI Express synchronous serial adapters, simplifying your transition to this next-generation PCI bus.
