Documentation missing "Jumps"

[fealXX]

Hi there,
I can't find a definition in the documentation (explaning the universeview) for the "Jumps" column.

Can anyone give me a hint where to find it or what it means?

Thanks,
Felix

Hi Felix,

Jump is a lost packet.
E.G. we get packet 1, then 3, but not 2

SeqErr is a packet arrived out of sequence.
E.G. We get packet 1, then 3, then 2

From your screen shot it appears you are getting network packet loss.

Should implement tooltips

sACN is a UDP transmission, correct? How does sACNView detect packet losses without a handshake between hosts?

There's now a full description of jumps and sequence errors in the 2.1 documentation at https://github.com/docsteer/sacnview/blob/2.1-dev/docs/documentation.md - this will appear on the main site when we make 2.1 a full release.

To answer @mrrodgers23 question, each sACN packet contains a sequence number that increments with every packet from a source - that allows us to track lost or out of order delivery
