D Series cable pin outs

When using a Digitool MX, the cable is fitted with a CAT5 (T568B) connector at both ends. However, when the NION is used, a serial D connector is used at the NION end, with a CAT5 (T568B) connector at the other end. For both the NION and Digitool, units that are daisy chained to the first D series unit use a cable with a CAT5 connector at both ends.
