Integrated CAN 2.0B controller operates at TTL logic levels supporting up to 1Mbps data rates. 16C554 UART provides 16-byte FIFOs, programmable baud rates to 921.6kbps, and full modem control signals. Conformal coating protects against moisture, dust, chemicals, and temperature extremes for harsh environment operation. Stackable PC/104 bus interface enables integration with embedded x86 systems. Common applications include industrial automation networks, SCADA systems, multi-drop sensor networks, vehicle diagnostics interfaces, and ruggedized data acquisition systems requiring multiple serial protocols. ## Function Provides 8 independent asynchronous serial communication channels supporting RS232, RS422, and RS485 protocols, plus up to 2 TTL-level CAN (Controller Area Network) ports, designed for flexible, high-speed serial and CAN bus interfacing. Implements industry-standard 16C550 UARTs and dual 82527 CAN controllers for robust data transmission and control. Designed as a PC/104 module with conformal coating for harsh environments, enabling integration into embedded computing platforms requiring reliable multi-protocol serial and CAN connectivity. Interfaces through PC/104 bus connectors and supports standard signaling for industrial automation, control systems, and data acquisition applications. ## Platform x86-based COM Express and Q7 modules, embedded systems requiring multi-protocol serial communication. Interfaces through standard COM Express Type 6 or Q7 connectors providing RS232, RS422, and RS485 serial protocols via DB9 or terminal block connections, plus TTL-level CAN bus interface. Supports industrial temperature ranges with conformal coating for harsh environments. Compatible with Linux, Windows, VxWorks operating systems. Connects to PLCs, industrial sensors, motor controllers, CAN networks, and legacy serial devices in factory automation, transportation, and outdoor applications. ## Application Provides expansion of embedded PC/104 systems with 8 independent asynchronous serial ports supporting RS-232, RS-422, and RS-485 signaling standards, plus up to 2 TTL-level CAN (Controller Area Network) channels for real-time, high-speed communication. Designed for integration in rugged, industrial, or automotive embedded applications requiring multifaceted serial communications and CAN bus interfacing. Conformal coating offers enhanced environmental protection, making it suitable for harsh conditions. Interfaces via PC/104 bus, enabling compact, stackable integration with other PC/104 modules and embedded controllers. Commonly applied in industrial automation, vehicle networks, data acquisition, and embedded control systems. ## Accessories PC/104 16-bit ISA bus interface via 104-pin (J1/J2) stack-through connectors. I/O is accessed via a 40-pin header (J3) for four configurable RS232/422/485 serial ports and a 10-pin header (J4) for two TTL CAN bus interfaces. Requires a PC/104 CPU module, power supply, and chassis. I/O breakout cables are needed for port access. The conformal coating option provides protection against moisture and contaminants. ## Interface One RS232/422/485 serial port module supporting multiple serial communication standards; includes a TTL CAN controller interface for Controller Area Network communication; conformal coated for environmental protection; module designed for insertion in compatible Eurotech embedded system mainframes or backplanes; connectors include a standard DB9 male serial port for RS232/422/485 signals and a 4-pin or 6-pin header for TTL CAN interface; used in industrial embedded applications requiring versatile serial and CAN bus connectivity. ## Images - - - -
