The SpaceWire Router Mk2S is a routing device that provides the essential capabilities now demanded of SpaceWire test and development equipment.

The SpaceWire Router Mk2S is suitable for all stages of SpaceWire equipment development: initial SpaceWire evaluation, instrument simulation, control system simulation, unit testing, integration support, and EGSE. It is functionally equivalent to the STAR-Dundee Router IP and the ESA radiation tolerant SpaceWire Router ASIC (AT7910E), available from Microchip.

The SpaceWire Router Mk2S provides eight SpaceWire interfaces, the ability to act as a time-code master, support for high speed data transfer, the capability to inject various types of errors on demand, and comes complete with highly optimised host software support for low latency transmission of SpaceWire packets directly to and from the host PC.

Expanding on the 10 years of knowledge and experience gained with the original SpaceWire Router-USB and Router Mk2, the SpaceWire Router Mk2S has new features to enhance its capability and has been migrated to support STAR-Dundee’s powerful software stack; STAR-System.​
