Hardware-silent CAN to USB interface targets sensitive and safety-critical systems
The instrumentation expert Kvaser (Mölndal, Sweden) is introducing the USBcan Pro 4xCAN Silent, a compact, multichannel four-channel CAN/CAN FD to USB real-time interface that is always silent on the CAN bus (‘listen only’).
Standard CAN interfaces receive and transmit CAN messages, enabling them to be used to configure the system to which they are connected. However, certain customers, particularly those developing highly sensitive autonomous or safety-critical systems, require CAN interfaces capable of listening only, so that the interface has no impact on the bus or surrounding systems. Kvaser’s new CAN interface is made silent through hardware and thus cannot transmit on the bus.
Listen-only interfaces are also used to prevent any application or third-party, such as a hackers, from impacting the CAN bus.
“The Kvaser USBcan Pro 4xCAN Silent was designed in collaboration with customers who wanted the highest performance and highest certainty from their CAN interfaces. While the USBcan range provides software-controlled silent mode, the customers in question wanted the guarantee of zero unwanted effects that only a hardware-implemented silent CAN interface can bring to the final test and validation stage of safety-critical systems,” explains Ludvig Wallander, Kvaser’s Director of Product Development.
The Kvaser USBcan Pro 4xCAN Silent handles reception of standard and extended CAN messages on the CAN/CAN FD bus with a high timestamp precision. With a standard USB connector at one end and four CAN channels in a single 26-pin HD D-sub CAN connector at the other, it includes a four-channel breakout cable with 9-pin D-sub connectors to connect with ease to separate CAN networks.
The Kvaser USBcan Pro 4xCAN Silent features Kvaser MagiSync, automatic time synchronization to achieve accurate and precise time stamping between multiple interfaces connected to one host computer. The Kvaser USBcan Pro 4xCAN Silent is compatible with applications that use Kvaser‘s CANlib, the software API common to all Kvaser hardware.
The Kvaser USBcan Pro 4xCAN Silent interface is available now with free software, free software updates and free support
