Unfortunately the 2 modules have slightly different implementations - someone didn't plan this whole thing out quite

And there's a small mod needed for the DDiv - this will be most, though I have just received a new board revision which fixes this (it looks different from behind, using 0603 passives so it is easy to distinguish).
Here's the testing Sequencing Frame I've been playing with - the final 2FW could either be the BBV or perhaps a Logic with a Diode Director..
The main clock of the sequence passes both to the DDiv buss input and then on to the left-hand-side clocking of the DDSR.
Note that I'm actually ignoring (not connecting) the Reset output pin of that header on the Sequence.
Then Gate B is passed to the right-hand-side clocking of the DDSR.
[in fact, the DDSR has 2 clocking input pins and each side can be set to one or the other with jumpers - hence the arrows showing how I've set the jumpers, one up & one down]
These are all MTA100 headers - I can easily enough provide the custom cables.
Just for reference, the 2pins headers are as follows:
DDiv - Pin 1 clock, pin 2 reset - there are 2 sets of headers, one as a pass-through to another module
DDSR - Pin1 clock 1, Pin2 clock 2
For the DDiv mod - this will affect basically ALL DDivs before now - sorry :(
Basically the Reset line needs a pull-down resistor - luckily it is pretty easy to add a 10K resistor.
In this pic I use an 0805 one though it'd be easy enough to use a through hole one.
One end goes to the diode, the other goes to the 0V trace that runs along the side of the board (marked with a green line below) - the soldermask can easily be scraped off the trace with a small flathead screwdriver.
Of course, if you're unsure of your ability to do this, do ask me for help - I can do it no problem, though obviously requires a return to base.
