The SCB-68 is just a dumb terminal block and the pins are labeled 1 through 68 which correspond to pins 1 through 68 of whatever DAQ board you are connected to. I'm assuming that you are going to be doing some sort of RS-485 emulation so connect your transceivers to whatever digital pins you want. It's the external transceivers that you have to concerned about wiring the TX/RX + and - lines.
