PC/104-Plus I/O Module With Opto-Isolated CAN Bus 2.0B Ports
Posted by on
Diamond Systems introduced their Janus-MM-LP family of CANbus 2.0 I/O modules, featuring independent isolation for each port plus data rates of up to 1 Mbps. These rugged I/O modules offer 2 or 4 CAN ports and are available in the compact PC/104 and PC/104-Plus form factors. The Janus-MM-LP-XT family of I/O modules offers two or four opto-isolated CAN 2.0B ports plus 16 digital I/O lines. Models are available with both PC/104-Plus (PCI + ISA) and PC/104 (ISA only) bus configurations. The CAN controllers are implemented as FPGA cores and feature standard and extended device identifiers as well as expanded TX and RX message queues for enhanced performance. Each port has its own combination isolator and transceiver chip. The module also offers 16 programmable digital I/O lines organized as two 8-bit ports.
The product was designed with harsh applications in mind, including latching connectors to further improve reliability. Extended temperature operation of -40 to +85 degrees C is tested and guaranteed. The modules are compatible with MIL-STD-202G shock and vibration specifications. Single unit pricing starts at $225 for the 2-port PC/104 model including all of the drivers and software.

A Comprehensible Guide to Controller Area Network
A Comprehensible Guide to Controller Area Network by Wilfried Voss represents the most thoroughly researched and most complete work on CAN available in the marketplace. Controller Area Network (CAN) is a serial network technology that was originally designed for the automotive industry, especially for European cars, but has also become a popular bus in industrial automation as well as other applications.
The CAN bus is primarily used in embedded systems, and as its name implies, is a network technology that provides fast communication among microcontrollers up to real-time requirements, eliminating the need for the much more expensive and complex technology of a Dual-Ported RAM. This book provides complete information on all CAN features and aspects combined with a high level of readability. Read more...
