Information the options of the USB-DMX converter
The options #1 and #2:
The option #2 consists to directly use a USB-DLP245BM module while the option #1 will directly use the FT245BM component with different CMS components necessary to its operation. One will obviously choose one or the other option.
The option #3:
This option must be wired; These components will permit the DMX512 data transmision to the lighting equipments.
The option #4 :
This option makes it possible to receive DMX channels and then send them to the PC. To be wired only if you need this functionality.
The option #5 :
This option is reserved for future use and will permit the standalone mode (self-contained functionality).
