Translation into binary data
In order to use these commands within a user application, they have to be translated into
raw data. This can be done by enabling the “Show Raw Data” feature in the command log
of the Director software as shown in Figure 27 below.
Figure 27 – Enabling raw data display
This raw data can then be transmitted to TWN4 via a virtual COM port. TWN4 will respond
to the request with the corresponding response as shown in Figure 28 below.
