Sealevel Systems, Inc. Introduces New Synchronous PC/104-Plus Module

Posted on

Sealevel Systems, Inc. announces the ACB-104.ULTRA, a PC/104-Plus RS-232/422/485/530 synchronous serial module. Boasting data rates up to 10M bps, the ACB-104.ULTRA is an ideal solution for satellite, radar, banking, and other specialized synchronous applications.

Based on the Zilog? Z16C32 IUSC?, the ACB-104.ULTRA includes an on-board DMA controller to eliminate bus bandwidth constraints and increase throughput. The ACB-104.ULTRA is also equipped with 256K of on-board RAM and a 32-byte FIFO buffer to maximize performance without increasing processor overhead. For maximum compatibility with a variety of host processors, the ACB-104.ULTRA can operate with either 3.3V or 5V signal levels.

Software support, critical for successful synchronous communication implementation, is provided through Sealevel?s SeaMAC driver. SeaMAC supports a variety of protocols under Windows 2000/XP including HDLC/SDLC, bi-sync, mono-sync, and raw (bit-shifter) modes. Clocking is selectable using the internal baud rate generator or from an external source.

The ACB-104.ULTRA, part number 3514, is priced at $499 in low volume quantities and is available from stock. Like all Sealevel I/O products, the board includes a lifetime warranty.
