DATAOPERATIONS  83
Once the M300 is running and playing back data you should always see time incrementing on your
display window and the data that was acquired will start to display.
WARNING:Alwaysmakesurethatafteryourecordthedatafile, youcanplaybackthedatafilewithoutany
errorsontheM300window.Thedatathatyouareplayingback,shouldlookexactlylikethedataacquired.
To change the playback speed you can go to the Playback Tab (See “Playback Tab” on page 68).
If you wish to speed up the playback and you don’t care about generating ASCII files, you can turn
off the ASCII record (See “Command Bar” on page 61).
To speed up the playback speed, when you want to generate ASCII files and don’t care about looking
at the M300 displays, turn off the displays (See “Command Bar” on page 61).
To pause the M300 while playing back data, you can click on the pause button (See “Command Bar”
on page 61). To un-pause the M300 click on the pause button again. The pause in the M300
window pauses playback, all displays will stop updating.
To rewind to the start of the data file use the rewind button (See “Command Bar” on page 61). This
gives the user a chance to play the data again, without having to exit M300 system. If you do this and
are generating ASCII data files you should be aware that some ASCII data might be there more than
once.
To go to the end of the file, you can click the end button (See “Command Bar” on page 61). Usually
you do this when you playback a data file from another node (remote over the network) where the
M300 is acquiring data and recording to a file.
Another useful button during playback is the next buffer button. This button allows the user to
playback one data buffer at a time. If the user holds down the next buffer button, then repeated
requests are made. Typically you use this while trying to narrow in on a particular section of the data
(See “Command Bar” on page 61).
BROADCASTINGDATA
These steps apply to both acquisition and playback mode.
In UDP mode you are not allowed to re-broadcast the data.
1. Prior to broadcasting data, ensure you have configured the M300 UDP properties correctly (See
“QNX Setup for M300 UDP Operations” on page 43).
