Default NX8 and Spektrum Programmer

I recently bought an NX8 bundled with a AR8020T and found out I had to buy a SPMA3065 TX/RX Programming Cable in order to access the serial number of the Rx.

Annoying, but I went ahead and bought one then successfully registered the RX.
Thing is though, even though it claims to be a Tx programming cable as well, there's no way I can see of connecting it to the NX8. The NX8 does not have a servo port on the back, so how do I connect it to this cable?

Connecting the Tx to the PC via a USB cable just enables charging or access to the internal memory, so that's not the way to go - so can I use this cable or have I just bought a very expensive way of registering my Rx?

In the old days of the DX8 Gen1 and DX18, you could access the system information and export the serial number as an XML format file which you could use on Spektrum's site to save you from having to type in that long serial number. My iX12 and iX20 were both done via direct connection with the WiFi and the internet. The cable you purchased will be able to let you update the new receivers and remote receivers like the 4651T, which I have done three of them now. I can also update the 6250 gyro and have done that with two of them so the cable is not a waste of money. It is a tool for the toolbox but direct programming of the transmitters from the computer is not on the cards, yet. I doubt it will take flight but you never know.

When they say that cable can be used for a transmitter, they're talking about the DXe or DXs - the models without LCD screens.

The other transmitters with LCD screens are programmed on the transmitter itself only. You can use the SD card or NX's internal storage to export/import your model setups and transfer them to another transmitter. NX will read DX files, but unfortunately it doesn't go the other way.

The NX transmitter automatically creates the XML file with the serial number now; you don't have to ask it to do that. Any time you connect to the internal storage via USB, you'll see a MY_NX8.XML file that you can use if you register on the Web site. Like the iX's, NX can also be registered over Wi-Fi.

I've picked out the highlights of the RCG thread on the NX's in my blog. Lots of good tips to help you get acquainted with the new radio.
