Provides serial data transfer capabilities with configurable signal levels for industrial and embedded applications. Designed for PC/104 and PC/104-Plus form factor systems with ISA and PCI bus compatibility. Features software-selectable protocols, programmable baud rates up to 921.6 Kbps, and multi-drop networking capability. Common in industrial automation, data acquisition, point-of-sale systems, and process control applications requiring reliable serial connectivity in space-constrained environments. ## Function Provides four asynchronous serial communication ports supporting RS-232 and RS-485 protocols, designed for PC/104-Plus compatible systems. Allows flexible data communication in embedded systems, with configurable baud rates and line settings. Interfaces via standard DB-9 connectors, supporting full-duplex RS-232 and half/full-duplex RS-485 modes. Capable of UART communication, facilitating serial interface expansion for industrial control, automation, or data acquisition systems. Integrates with systems via a PCI-to-PC/104-Plus bridge for seamless functionality within hardware platforms. Offers ESD protection for reliable operation in rugged environments. ## Platform This module provides four configurable serial ports (RS232/RS485) for industrial applications. It operates on a PCIe/104 form factor, designed for rugged embedded systems. It interfaces with a host CPU via the PCIe bus, supporting high-speed serial communication. Common applications include connecting to serial devices, industrial automation, and data acquisition. ## Application Facilitates high-speed data exchange in embedded systems through four independent serial ports, switchable between RS-232 and RS-485 protocols. Designed for PC/104-Plus form factor with ISA and PCI bus interfaces, supporting data rates up to 921.6Kbps with 16550 UART compatibility. Features software-configurable termination resistors, auto RS-485 direction control, and extended temperature operation. Commonly used in industrial automation, transportation systems, medical devices, and telemetry applications requiring reliable serial communications in harsh environments. ## Accessories PC/104-Plus host system and chassis. Features self-stacking PC/104-Plus bus for power/data, comprising a 104-pin ISA (P1) and 120-pin PCI (P2) connector. Four serial ports interface via one 26-pin IDC header, requiring a breakout cable to four DB9 male (D-subminiature, 9-pin) connectors for RS232/RS485 communication. ## Interface Four serial ports, each hardware configurable for RS-232, RS-422, or RS-485 signaling; UARTs with 64-byte transmit and receive FIFOs supporting data rates from 50 bps to 1.8432 Mbps; supports RS-485 full duplex, half duplex, and multi-drop modes; PC/104-Plus stackable module with PC/104-Plus bus connector for power and data interface; no onboard connectors, external cabling required for RS-232/422/485 signals; operating temperature -40°C to +85°C. ## Images - - - -
