High Performance CAN Functionality
The Janus-MM-4LP-XT I/O module offers two or four CANbus 2.0B ports with opto-isolation plus 24 digital I/O lines. Models are available in both the PC/104-Plus and PC/104 form factors. An FGPA core houses the CAN controller logic and provides data rates up to 1Mbps. Each port supports standard and extended frames as well as expanded TX and RX message queues for enhanced performance. Each port has its own combination isolator and transceiver chip. The Janus-MM-4LP-XT fits a wide variety of rugged and on-vehicle embedded serial I/O application needs.
Digital I/O
Janus-MM-4LP-XT offers 24 programmable digital I/O lines organized as three 8-bit digital I/O ports.
Rugged Design
Janus-MM-4LP-XT 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 module is compatible with MIL-STD-202G shock and vibration specifications.
Key Features
All four CAN ports on the Janus-MM-4LP-XT are driven from an FPGA-based CAN 2.0 bus controller core which provides full CAN2.0B functionality. Each port has an Analog Devices combination isolation and transceiver chip, independently isolating it from the host system and other ports to eliminate sensitivity to noise and ground shifts in the network.
The product has several jumper configurable options including CAN termination and bias. The digital I/O logic level and pull-up / pull-down resistors are also jumper configurable.
For additional ruggedization, zero ohm jumper-bypass resistors can be installed in any configuration.
Software Support
Janus-MM-4LP-XT comes with a basic CAN driver for Windows 7, XP and Linux 2.6. The driver supports dual-independent and dual-redundant modes.
