All of the attempts were directly to the mount, not through the hand controller (assuming that is what Hbx is for).

OK. Just many people might have read the post as using std USB2Serial adapters, which are very different to USB2TTL adapters.

Each of the other modules I have are both 3.3V and 5V via a selector.

I originally breadboarded my own adapter using a max232, but the recent explosion in arduino/etc/etc plugboards means you can pick up a USB2TTL board quite cheaply. If you had std USB2TTL boards, i cant understand why they didnt work, unless there is a wiring error somewhere. All good fun :-)
One interesting bit is my EQ6Pro ( mount ) uses 5V TTL
The V3 and V4 Handboxes use 5V TTL to the mount
My AZEQ5 ( mount ) uses 3.3V TTL, even tho the Hbx is 5V TTL
They all play happily so far,
but putting true rs232 into them may result in pain,
so people need to be careful in what they do.

If memory serves, on the module TX was Green on the network cable, RX was Blue/White and Ground was Blue & Orange/White.

That sounds right
I made a tapping cable using a std cat5 and got
Brown = 12V
Brown Stripe = 12V
Green = Hbx to scope ( or module to mount )
Blue Stripe = Scope to Hbx ( or mount to module )
Blue = gnd
Green stripe = drop??
Orange = ???
Orange Stripe = ground
