Black Box’s pre-constructed cables use Pinout 3B. WE MAKE NO DISTINCTION BETWEEN PINOUTS 3A AND 3B. In our system, we never look at pins 1 or 6 on the PC side, so it makes no difference if we use that wire or not. With our standard 6 conductor cable we don’t have enough wires to connect it anyway, so we leave it out.
Here is when it is ok to use each cable (items in yellow are functional, but “less preferred”)

*Remember – you can’t use SEND NOW when drip feeding. This column refers only to transfer in/out of memory. When drip feeding, use Wait for XON or the DNC button in PC-DNC Editor.
** Haas and Fadal machines need only 2, 3, and 7. Pinout 1 doesn’t even need the 4/5 and 6/8/20 jumpers.
*** Parameter to disable DR signal check required to use pinout 3. These devices do NOT permit the use of pinout 3 with the SEND NOW button in their default state.
