Asynchronous Serial I/O Boards

Our PCI-bus Serial Boards offer the widest choice of I/O connectivity available. Products include RS-232, RS-422 and RS-485 solutions.

These PCI boards are available with a wide range of accessories and excellent software drivers to make installation easy.

Our Low Profile Universal Bus PCI Boards are designed for many of today’s newer computers that do not include standard size PCI slots. Each Low Profile Universal Bus PCI board meets the requirements for the MD1 Low Profile specification as defined by PCISIG in PCI 2.2 "Low Profile Addendum".

Low Profile boards also feature Universal Bus (3.3 and 5.0V) compliance as required by PCISIG specifications 2.3.

These 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.

Our 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.

Impulse continues to provide a full line of ISA serial products to support legacy applications.

All of Sealevel's quality products come with a Lifetime Warranty that guarantees the performance of the components over the life of the product.

Designed to meet the core needs of PC/104 applications requiring high reliability, small size, and long-term availability, our PC/104 Modules offer easy RS-232, RS-422, and RS-485 serial expansion for the PC/104 stack.

Our PCMCIA Cards allow asynchronous RS-232, RS-422, or RS-485 expansion via any available PCMCIA slot. 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.
