The DMC-40x0's optoisolated inputs are rated to operate with a supply voltage of 5–24 VDC. The optoisolated
inputs are powered in banks. For example, INCOM (Bank 0), located on the 44-pin I/O (A-D) D-sub connector,
provides power to DI[8:1] (digital inputs), the abort input (ABRT), reset (RST), and electric lock-out (ELO). Table 3.17
shows all the input banks power commons and their corresponding inputs for 1-4 axis controllers and Table 3.18
shows the input banks for 5-8 axis controllers.

The full pin-outs for each bank can be found in the Integrated Components, pg 211 under the ICM option ordered:
A11 – ICM-42000 (-I000), A12 – ICM-42100 (-I100), or A13 – ICM-42200 (-I200).
