The power source functions as Data Circuit-terminating Equipment (DCE). The cable
connecting to the Data Terminal Equipment (DTE) should be straight-through (one-to-
one contact connections). For EMC considerations a ferrite core can be added to the
cable Ametek P/N: 991-642-28, Manufacturer P/N: CS28B0642.
