The serial number 151xxx indicates it is an unblocked version. There are however two versions of the AOR CC8200 cable.
If you have an unblocked AR8200Mk3 and your serial number is less than or equal to 152831, then you need AOR CC8200A cable.
If you have an unblocked AR8200Mk3 and your serial number is greater than 152831, you need an AOR CC8200B cable.
Based on your serial number, you need the AOR CC8200A cable. The two cables are similar but the plug that goes into the receiver is a very different size for the two versions. Both versions have a female DB9 plug on the other end of the cable.
I use Butel software for my AR8200 receivers and it works ok. The key is finding a DB9 to USB cable that Butel Software will recognize on a Windows 10 computer. The 8600 has a female DB9 plug on the back of it, so the DB9 to USB cable that works with the AOR CC8200A cable will also work with the 8600 and thus plug directly into the 8600. I also have used Butel Software for my AR8600Mk2 and it works exactly the same as it does for the AR8200 series. The same version of Butel Software works with both receivers (8200 and 8600). In other words, you don't need two copies of the software.
