@IanSJohnston@NNNILabs https://t.co/TOxRZR8Mdl they do exist, but they are quite pricey! Personally though with this quantity I think IEC distribution works better.
@AvroVulcanXH607 I have a 1U WVR that appears to have the same/similar rails, although I suspect it is a bit newer that what you have in the picture. The sliding parts have this label on which might help with an internet search?
@AvroVulcanXH607 Bringing back memories seeing this, around 15 years ago I was dealing with Quartz stuff quite a bit. Quartz devices communicated with each other using Q-Link which used a single BNC, may have communicated with other manufacturers devices via RS-422.
