Transmission Mode
You can either transmit the specification continuously or transmit it
n
times.
Select
Transmit Continuously
to transmit activated streams in a loop until the
module is stopped.
Select
Transmit Spec (N frames)
to transmit activated streams a specific number of
times. The number of streams does not necessarily equate to the number of frames
transmitted.
Caution
The transmission mode should always be set prior to
loading the module. The transmission mode is not saved
as part of the Transmit Specification. Unless you set the
transmission mode, you may inadvertently flood the
network with packets.
The
Transmission Status
area of the dialog box provides status information about
the transmission. The fields indicate the speed of the currently active module, the
number of streams that are active, and the total memory in the buffer required to
transmit the specification. The total memory increments as you add/change streams,
giving you an instant reflection of how much data you are transmitting. A warning
message is shown if you exceed the transmit buffer size.
Specifying Transmit Data
Data fields for the Transmit Specification can be modified in two ways: by using the
Packet Editor or by changing the data fields shown in the
Transmit Specification
dialog box. If you are inserting a new stream, you can use a template as the starting
point for packet data. The insertion of a new packet into the
Defined Streams
list box
will appear below the currently highlighted packet stream.
Packet Editor
The packet editor can be used to modify the contents of a stream data. The editor
provides two views of packets, a decoded view and a hex view. Edits can be made
within either view. Select the
Edit Data
button to bring up the editor.
