Make sure all the Eprom versions are the same on all the DIO-8 cards, if they are not the same it will not work.
FYI: lifted from here...
http://www.mackie.com/support/FAQ/D8B_d ... .html#dio8Version 1 (M-108C, V 1.01) –16-bit only, SYNC output is in phase with the word clock (incorrect according to the TASCAM standard).
Version 2 (Version 2, 127 Ver 2) – 24-bit throughput, SYNC output phase with respect to word clock is still incorrect.
Version 2.1 (Ver 2.1) – 24-bit throughput, SYNC output phase corrected to work properly with the older DTRS recorders.
Note: When connecting DIO-8 cards together, be sure they are all running the same EPROM version.
This above is what I was talking about on another post... Version 2, 127 Ver 2 has the clock signal in phase with the clock card and Mackie fixed it with Ver 2.1 to flip the clock signal so it works with the Tascam machines and now out of phase with the clock... but what matters most is that ALL cards run the same version whatever that may be - if one card is different it will not work, period.
FWIW, the simplest way to fix that problem if you have it and also, if you have the money, is to obtain three more OPT-8 cards and sell the DIO-8 cards. It'll run you about $300 USD where I sit.
Sorry you are having so much trouble, I can relate I went through a lot of similar experiences. When I got it working it was a very good day.
You need midi between both machines. Please disregard information between brackets it is wrong
[if you want to check MIDI easily, obtain a 9-pin straight through D style cable, Pin 1 to Pin 1, Pin 2 to Pin 2, ect... this will positively connect it the right way. This will only connect the HDR and the d8b together]
- if at a later time you need to introduce MIDI to other pieces of gear to become part of the system, (i.e. computer, keyboard, recorders, washing machine
) you will need the break out cables on both the HDR and the d8b. Everything needs to be connected and the BIOS settings also need to be checked and double checked. All of this can be found in the manual and also the DATABASE has information about problems and offers a way to fix the problems; the Mackie FAQS page is also a help.

http://www.mackie.com/support/FAQ/D8B_detailed.htmlI am not familiar with any of the Mackie recorders... but I am sure that there is similar information on those too.
Hope this helps,
