Depending on the license keys that are installed, you can select all kinds of formats and optionally sub
formats where needed. There are formats for the SBP protocol, IIDC protocol, IP4 protocol and AV/C
protocol. You can also select the format 'unformatted' to be able to set any kind of condition on any bits.
Now we will describe the different parts of the Data Values box:
payload size (bytes):
Here you can enter the payload size of the packet expressed in number of bytes. It will specify the size of
the data shown in the 'Payload' tab. Changing the value will also change the size (bytes) value in the
'Payload' tab. This value will automatically be adapted if you specify a new value for the 'Data-Length
Async. packet' field in the Header Values box.
Format tabs
The 'Payload' tab will always be present. It describes the whole payload. If a field can be described with a
sub-format, an additional tab will be present for the format of that field. See 'command' tab in the example
above. All tabs have the same parts in it:
·
format. With this combo box you can select the format of the packet or sub-format of the field. Note that
the formats you can select from depend on the license keys that are installed for the currently
connected Analyzer. If no Analyzer is connected, there will only be the unformatted option.
· size (bytes). Here the number of bytes will be displayed that correspond to the data in the selected tab.
For the 'Payload' tab this will be the size of the complete payload as indicated in the payload size
(bytes): above it.
· parameter. Sometimes a format may need extra parameters to be able to format the data correctly. In
the example below for instance, the selected format is one of the command sets for the command data
for the SBP2 protocol. Command data is returned as a reaction on a command. In this case, the
command has an operation code that determines the format of the command data. Thus to be able to
format a command data packet, you will need to enter an operation code. In such situations, a
parameter combo box will appear. Here you can select a parameter and enter the value for it in the box
