Hi all

I'm setting up a couple of OP TCBs for the first time and encountering a range of issues.  Help will be appreciated on any of the issues outlined below.

1a) Ports:
I tried to connect a TCB to a laptop running Windows 10.  No COM ports are showing / available. 
Question: What should I disable on the laptop so that I can see the relevant ports?

1b) Ports:
I tried a laptop running Windows 7.  COM3 and COM4 show up, but I can't connect to the TCB via either one. 
Then, occasionally (?) after plugging and re-plugging in the TCB and receiver, another Port appears (COM6 or COM7) and when I select one of these the laptop connects quickly to the TCB.  If I dither about then the COM6 / COM7 will disappear.
Question: What should I do to ensure that the relevant port is always displayed once the TCB is plugged in?

2) "Radio Not Ready" "The radio is not detected" (see attached file)
I've tried a few radios and receiver combinations using the Windows 7 laptop mentioned above (as soon as COM6 or COM7 manifest themselves).  These include a Taranis radio (with FrSky or Flysky rxs bound) and Jumper T12 (with FrSky, Flysky and Orange rxs bound).  I've tried the top row of pins and the bottom row of pins on the OP TCB and keep getting this error message after hitting the Read Radio button*. 
Question: What am I missing / doing wrong?

* Note that I did manage to read a friend's TGY-i6S radio, which is bound to a TGY-iA6C receiver, and can now drive his tank around.  Wires to the upper hull and turret and airsoft are broken so I will need to attend to these next, and there is no sound.  Since this Tx/Rx system is the only one that's working at the moment I'll persevere with that tank before I ask any more questions.  I realise I need to rewire the airsoft unit anyway so I'll follow that helpful video tutorial next, and any other advance tips would be welcome. 

All the best,
RCBM
