the 55025 manual says it can do synchronous and asynchronous flashing mode.
Does anyone know what that actually means?

Perfect... Why didn't they print this in the manual!
Thanks for your help

Synchronous
In general, synchronous (pronounced SIHN-kro-nuhs, from Greek syn-, meaning "with," andchronos, meaning "time") is an adjective describing objects or events that are coordinated in time. In information technology, the term has several different usages.
1) In telecommunication signaling within a network or between networks, synchronous signals are those that occur at the same clock rate when all clocks are based on a single reference clock. (Plesiochronous signals are almost but not quite in synchronization and asynchronous signals are those that run from different clocks or at a different transition rate.)
2) In program-to-program communication, synchronous communication requires that each end of an exchange of communication respond in turn without initiating a new communication. A typical activity that might use a synchronous protocol would be a transmission of files from one point to another. As each transmission is received, a response is returned indicating success or the need to resend. Each successive transmission of data requires a response to the previous transmission before a new one can be initiated.
Synchronous program communication is contrasted with asynchronous program communication.
Asynchronous
In general, asynchronous (pronounced ay-SIHN-kro-nuhs, from Greek asyn-, meaning "not with," and chronos, meaning "time") is an adjective describing objects or events that are not coordinated in time. In information technology, the term has several different usages.
1) In telecommunication signaling within a network or between networks, an asynchronous signal is one that is transmitted at a different clock rate than another signal. (Plesiochronous signals are almost but not quite in synchronization - and a method is used to adjust them - and synchronous signals are those that run at the same clock rate.
2) In computer programs, asynchronous operation means that a process operates independently of other processes, whereas synchronous operation means that the process runs only as a result of some other process being completed or handing off operation. A typical activity that might use a synchronous protocol would be a transmission of files from one point to another. As each transmission is received, a response is returned indicating success or the need to resend. Each successive transmission of data requires a response to the previous transmission before a new one can be initiated.

Interested in vintage commercial vehicle, trams, t
All of which, whilst interesting, and will get you (nearly) full-marks in the exam..
Has very little to do with the 'mark to space' ratio of alternating function outputs of a decoder flashing a couple of bulbs/LED's.
(tongue very firmly in cheek!)
And I thought it was only cats that could do that!
I zink it lorst zumzing in der translation!

Please do NOT enter the arena of 'non return to zero'(or inverted), phase encoding, run length encoding, ad nauseam, oh, and my favorite: 'non-conductive mid-air splice'. I retired to get away from those outdated phrases. This hobby is almost too electronic for me now. Me thinks I will become a Luddite and pitch my MTS, MZS, DCC, Revolution and homebrew stuff in the closet (again) and restrict myself to DC, switches, diodes, and magnets. They are almost 100% compatible with senility.
