STAR-Dundee’s SpaceWire PXI platform has now been updated to include a number of enhancements to single point of failure FMECA (Failure Mode Effects and Criticality Analysis) protection. The SpaceWire PXI Mk2 range of products now supersedes the original SpaceWire PXI products, offering all the features present in the original products and full backwards compatibility.
At STAR-Dundee we continually work to improve our products. When these improvements are to software or to a device’s firmware, we make these updates available through our website’s Product Support section. You can gain access to these downloads by registering your product. When the update is to the hardware, we endeavour to ensure backwards compatibility with previous generations of the product. We indicate the version number of a product using the mark designation system, abbreviated to Mk. For example, the SpaceWire PXI Mk2 (Mark Two) is the second generation of our SpaceWire PXI product range.
The SpaceWire PXI Mk2 is available in the following variants:
SpaceWire PXI Interface Mk2 4HP
SpaceWire PXI Interface Mk2 8HP
SpaceWire PXI Interface Mk2 with RMAP Target 4HP
SpaceWire PXI Interface Mk2 with RMAP Target 8HP
SpaceWire PXI Router Mk2
The SpaceWire PXI Mk2 products can be used in cPCI or PXI backplanes, provide link speeds of up to 400 Mbit/s and, as with our other interface and router products, are accessed using our STAR-System software suite. The 8HP variants of the PXI Interface Mk2 and PXI Interface Mk2 with RMAP Target have 4 general purpose bi-directional triggers on the front panel which can be used to sequence events such as the transmission of time-codes or data packets, or to indicate events to an external device such as an oscilloscope. A full FMECA guide for the SpaceWire PXI Mk2 boards is available on request.
With the ongoing COVID-19 pandemic requiring significant changes to our daily lives, we are striving to maintain productivity while protecting our employees. We are following the guidance of our governments in the UK and Spain, both to ensure the safety of our employees at STAR-Dundee and STAR-Barcelona, and to help minimise the spread of the virus.
The health and safety of our employees is our primary concern and the majority of our team are now working from home. Our homeworking engineers have all of the equipment they need to provide support but, in some cases, this may take slightly longer than normal.
There is a small team working in our office in Dundee, primarily focussed on fulfilling orders. We are grateful to our manufacturers and suppliers who are continuing to deliver to us. Our order fulfilment team is endeavouring to keep customers informed of likely delivery dates and ensure orders are delivered on time.
Everyone at STAR-Dundee would like to extend our best wishes to you all during these challenging times. We hope you are all safe and well.
In order to validate and debug complete SpaceWire systems it is very useful to be able to record and view the traffic on multiple links. Thorough validation can also require very large quantities of SpaceWire traffic to be stored and analysed.
The SpaceWire Recorder Mk2 can record and display the SpaceWire traffic on up to four SpaceWire links. It records SpaceWire packets, time-codes and link errors to solid-state disk, along with time information, and then displays these in network and packet level views ready to be inspected. The quantity of data that can be recorded and viewed is limited only by the size of the solid-state disks used (960 GB).
Recording statistics provide a summary of recording contents and help highlight any concerns. Built-in search helps to validate and navigate recorded traffic. To help automate SpaceWire traffic validation, all or part of a recording can be exported to CSV formatted files and then easily interpreted by custom software.
More information about the SpaceWire Recorder Mk2 is available on the product page.
A new version of our SpaceWire EGSE and Device Simulator has been released! Like its predecessor, the SpaceWire EGSE Mk2 can be used to very quickly create SpaceWire instrument and equipment emulations. This is done using a scripting language designed specifically for SpaceWire applications.
The SpaceWire equipment behaviour required can be quickly and accurately defined in a script. The script is then compiled on a host PC and the resulting configuration file loaded into the SpaceWire EGSE Mk2 unit. The EGSE Mk2 then immediately begins to operate as defined in the script, functioning independent of software, resulting in real-time performance and precise emulation.
The SpaceWire EGSE Mk2 supersedes the original SpaceWire EGSE. It now supports SpaceWire link speeds up to 400 Mbit/s (previously 200 Mbit/s); the on-board memory in which packet data is stored has been increased in size to 512 MB (previously 128 MB); and a USB 3.0 interface (previously USB 2.0) is now used to connect the unit to a host PC. Compared to the original SpaceWire EGSE, these improvements mean traffic can be transmitted and received at higher link speeds; a larger quantity of pre-defined packet data can be stored in memory; and compiled scripts can be loaded into hardware faster.
Essential for validating and debugging a SpaceWire link, our latest model of the SpaceWire Link Analyser is now available!
The Link Analyser Mk3 can capture and display bi-directional traffic travelling over a link; it can display live link statistics; and it can output decoded SpaceWire link characters and events to an external logic analyser. The traffic visibility this provides greatly helps to validate a link is operating correctly and aids debugging when problems are detected. Without such traffic visibility, there is an increased risk that issues go undetected and problems may take significantly longer to resolve.
Building on the capabilities of previous models, both the Link Analyser hardware and software are significantly improved. Hardware improvements mean much larger quantities of traffic can be captured, on SpaceWire links operating at faster speeds, and can be uploaded to a host PC more quickly. The software has been completely rewritten, retaining familiar views and useful functionality from the Mk2, whilst removing limitations of the previous software and adding new features.
We’re aware that many users of our SpaceWire and SpaceFibre products mount these in 19″ racks and we’ve seen many different approaches to achieve this, with some products more suited to rack mounting than others. To make it easy to mount STAR-Dundee products in a 19″ rack, we’ve now introduced the Rack Mounting Kit Mk2, which can be used to mount many of our products in a 19″ rack. The kit includes all the blanking plates, bolts and nuts required to mount your products. There are also fastening straps provided to hold down any power supplies and for smaller products such as the SpaceWire Brick Mk3 and SpaceWire Isolator, device mounts are provided.
The full list of products supported by the Rack Mounting Kit Mk2 is provided below:
We are pleased to announce the availability of our all new SpaceWire Conformance Tester Mk2.
Building on the success of the original SpaceWire Conformance Tester, the Mk2 has a brand-new hardware design that connects to the computer over a USB 3.0 (or USB 2.0) connection. It is now rack mountable using our rack mounting kit. The Conformance Tester Mk2 supports testing of SpaceWire link speeds of up to 400 Mbit/s and comes with the newest version of the GUI software.

The STAR Fire Mk3 can transmit and receive both SpaceWire and SpaceFibre traffic; it can interconnect SpaceWire equipment to a SpaceFibre network; and it can operate as a SpaceFibre link analyser, capable of unobtrusively capturing and displaying SpaceFibre traffic. Leveraging these capabilities, it is possible to emulate, stimulate, debug and validate SpaceFibre enabled equipment.
Previous versions of the STAR Fire were created whilst we developed the SpaceFibre standard, helping to prove the technology and providing early adopters with access to test equipment. Building on the previous STAR Fire models and our expertise in SpaceFibre, both the STAR Fire Mk3 hardware and software have been significantly improved, resulting in a comprehensive test and development platform.
