At the top of this window you can find the toolbar with buttons for starting, uploading and stopping the
Generator. Before starting the Generator, you first have to upload the generator data to the Analyzer. This
data can be specified in the "Mil1394 Streams" generator page, where you can define isochronous
sequences. Sequences are indicated by blue rectangles on the time line of a slot. This can be seen in the
picture above.
An isochronous sequence is specified by a a start frame number, the length in number of frames, the
speed, a setting for auto heartbeat, a setting for auto VPC calculation and contents of the isochronous
packets to be sent during these frames. During generation each sequence will result in the generation of
an isochronous packet for each isochronous frame at which the sequence is defined. The channel, speed
and contents will correspond to the values specified for the slot the sequence is placed in. If more than
one slot is defined for some isochronous frame, then the order of isochronous frames will depend on the
specified priorities.
An isochronous sequence is placed in a 'slot'. In the example window above, a couple of slots are defined.
The names of the slots are listed on the left side of the window and their 'time' lines are drawn to the right
of their names. Before creating any sequences, at least one slot must be defined. To add a slot, open the
slot definitions by selecting it from the Generator menu or pressing the corresponding toolbutton.
To create an isochronous sequence, click on the 'time' line of the slot you would like to create a sequence
for. Initially, the sequence will occupy the complete slot. However, the left and right edges of the
sequence can be moved by dragging them with the mouse. By doing this, the sequence start and end
frames can be changed.
Now you have defined the start frame and length. Both start frame and length can be changed at any time
as long as they do not overlap another sequence in the same slot.
To change the packet contents for the packets in a specific sequence, click on the sequence rectangle to
select it. The selection is indicated by a red surrounding. If a sequence is selected, the right side of the
generator window will represent the packet contents of the selected sequence. It is now possible to fill the
sequence with data from a template, file or manually.
