Janus-MM-LP 2- or 4-Port PC/104-Plus CAN I/O Module Targets Rugged Networked Applications

Diamond Systems Corporation, a leading global supplier of compact, rugged, I/O-rich embedded computing solutions for real-world applications in a broad range of markets, unveiled the Janus-MM-LP family of CANbus 2.0 I/O modules, featuring independent isolation for each port plus data rates up to 1Mbps. 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 Janus-MM-LP I/O modules come with a basic CAN driver for Windows Embedded 7 and Linux Ubuntu 12.04LTS. Also included free with the product are Windows and Linux APIs and monitor programs. The monitor program allows the user to set, manage and observe all of the functions and traffic on the CAN ports and digital I/O lines.

Janus-MM-LP-XT CANbus 2.0B I/O modules fit a wide variety of rugged and on-vehicle embedded networking application needs. The product was designed with harsh applications in mind, including latching connectors to further improve reliability. Extended temperature operation of -40°C to +85°C is tested and guaranteed. The modules are compatible with MIL-STD-202G shock and vibration specifications.
