d12's data sheet has an incomplete schematic for data exchanging.
the rest of pins are connected in this way:
rst-> vcc (ou can use a 1-10 K resristor)
sus->Gr
EOT_N->Vcc by a 4.7K
EOT_N->Gr using a 1 M Res.
Ack_n->Vcc
there is no need to connect other pins

my D12 is working with this pinning.
I hope it works for u too.
