Sealevel Systems, Inc. Introduces Low Profile PCI Bus Sync/Async Adapter

February 24, 2003

Sealevel Systems, Inc. announces the ACB-232.LPCI, a new single-port low profile PCI RS-232 Synchronous/Asynchronous serial interface, as an addition to its popular product line.

The ACB-232.LPCI is the ideal solution for developers integrating applications where the PCI bus and HDLC/SDLC or Asynchronous communications is required. Its ability to communicate reliably at speeds up to 128K bps in Windows makes the ACB-232.LPCI card ideal for digital service line technology applications.

The ACB-232.LPCI card is based on the Zilog 85230 ESCC. This synchronous controller is in widespread use today in a variety of applications including military and aviation simulations, missile guidance, and commercial digital communications.

This low profile synchronous adapter meets the requirements for the MD1 “Low Profile” specification as defined by PCISIG in PCI 2.2 “Low Profile Addendum.” Sealevel Systems, Inc. ships each adapter with both the low profile bracket and the standard profile PCI slot bracket, offering the customer versatility in installation. The ACB-232.LPCI features a Universal Bus (3.3V and 5.0V) as required by PCISIG specifications 2.3.

Software developers will appreciate the board’s optional OEM security feature. This feature allows the developer to request a specific 2 digit hex value to be programmed into the cards at Sealevel’s factory for recognition during software initialization. Unauthorized software duplication is virtually eliminated if this option is implemented.

SeaMAC, Sealevel’s family of Sync/Async software drivers for Windows NT/2000, supports the ACB-232.LPCI card. SeaMAC allows the application developer to focus on the application details while reducing time to market. SeaMAC contains applications including SeaBERT, a Bit Error Rate Test application for verifying serial link reliability, SeaTERM, a binary and text file transfer application, and ProTest, a simple protocol analyzer application for monitoring system traffic. An HDLC/SDLC driver for Linux is planned for future development.
