Introduction
4Links’ EtherSpaceLink family Multi-link SpaceWire Recorder (MSR) is a rack-mounted SpaceWire recorder that
allows SpaceWire traffic to be captured, buffered and transmitted over Ethernet via a TCP/IP socket connection.
TCP/IP is a standard interface mechanism supported by all major operating systems, so no additional software
drivers are required.
The MSR provides for detailed analysis of SpaceWire networks, including routing switches. Recordings can be
made of all of the SpaceWire traffic, with each packet time-tagged to a resolution better than 2 ns. There is no
limit to the length of the SpaceWire packets that may be captured and transferred.
Multiple MSRs can be synchronized to within 10 ns to provide uniform time-tags across a system, even if that
system has many SpaceWire links and the recordings are being made onto different computers. Software is
provided to help manage and search the recordings.
The basic MSR-RG40x unit provides data recording facilities, event reporting and time-tag capture for some
(or all) of the tokens in the SpaceWire streams. It may be extended with an option to provide waveforms that
show the precise state of the SpaceWire signals around the time that an error was detected. This optional
capability can be added as a simple field upgrade by replacing the removable memory card installed in the
front panel of the unit.
The Multi-link SpaceWire Recorder is available to record 1, 2 or 4 SpaceWire links using two adjacent ports per
link. These ports may be mounted on the front panel of the unit (see the picture above), or on its rear panel.
