Anyone got one of these hanging around, or know a cheap way to get the adaptor (or the pinouts). I only need it to do one flash so buying a $50 cable seems a bit excessive...

This is the cable I am after: https://www.aap.co.nz/shop/Tools/USB+D-LINK.html

I suspect by the way Dlink is mentioned that this is simply a USB to RS232 serial adapter? If so you can pick these up on Trademe for a few bucks.

No doubt.. It's the proprietary connector and lack of any documentation on the pinout that I suspect is the barrier to just using a generic USB to RSR232 adapter.

Information wants to be free. The Net interprets censorship as damage and routes around it.

You are correct. The adapter is a Simple USB to Serial adapter (TTL, not RS232).

The connector's pinout is a little confusing but here it is:

1 - Ground
2 - TX
3 - RX
4 - Not Connected
5 - Ground
6 - Ground
7 - Ground
8 - 5V Status? (Pulled up to 5V with 4.7K Resistor)
9 - Board Config? (0Ohm resistor to Ground)
10 - 5V
I may have pins 2 and 3 mixed up, but simple trial and error should get that sorted.
