Delivery was very quick. But without manual without description, without software. What's already on it? What else do you need? Since you do not know what one has to do and is overwhelmed as layman hopeless. Normal would the seller ask for what cable provider you need the module and program accordingly. For sure a matter of 5 minutes. Here you will but left completely out in the cold, do not know what you need where as download. Firmware? What? Where? Software? What, Where? What? Here are 4 switches off, no one knows what and what one must evtl.machen there. Before you do something wrong, you can send it back really quickly.
Incidentally, I have 20 years of PC experience but something not yet have to experience.
