The IP-Octal 485 is a single-wide Type I IndustryPack module delivering eight EIA-485 asynchronous serial ports for industrial control and data acquisition applications. Built on the Signetics SCC2698B octal UART, it provides programmable serial communication with configurable baud rates, data bits, parity, and stop bits across all channels.

– Key Features
• Eight independent serial channels eliminate external multiplexing complexity
• Programmable communication parameters enable adaptation to legacy and modern protocols
• Four on-module timers support real-time control tasks
• 32 interrupt sources with masking and vectoring allow flexible system integration
• Configurable strobe pin extends timing synchronization options
• Low power consumption reduces thermal load in confined carrier environments
– Typical Applications
Industrial serial networks, distributed I/O systems, multi-channel data logging, process control interfaces, and legacy equipment integration requiring EIA-485 connectivity.
– Compatibility & Integration
Complies with ANSI/VITA-4 IndustryPack standard. Compatible transition modules include XM-OCTAL (19″ rack-mount DB9 females), XM-OCTAL-6U-D (6U-mount 25D females), XM-OCTAL-6U-RJ8 (6U-mount RJ45), and XM-OCTAL6URJ16 (6U-mount RJ11). Carriers with Champ50 connectors are not compatible. Carriers lacking ID PROM write capability may require on-module memory allocation for interrupt vectors.
