Abaco Systems / SBS / Greenspring IP-Octal-422 IndustryPack Module with Eight EIA-422 Asynchronous Serial Ports

The Abaco Systems (formerly SBS/Greenspring) IP-Octal-422 is an IndustryPack module designed to provide eight EIA-422 asynchronous serial ports for industrial communication applications. This module utilizes the Signetics SCC2698B octal UART to manage the serial communications, with each channel featuring a three-character FIFO buffer on the receiver to extend interrupt servicing latency. The IP-Octal-422 supports eighteen programmable baud rates, reaching up to 38.4 kbps, and offers configurable settings for bit length, parity, and stop bits. Additionally, it includes four independent 16-bit timers and eight general-purpose input lines with TTL switching levels. Two of the serial channels can be configured for Direct Memory Access (DMA) operation. The module complies with the ANSI/VITA-4 standard for IndustryPack interfaces and connects via a standard 50-conductor ribbon cable, with an optional connection panel available for rack mounting.
