Digital Communications – RS232

connection to a personal computer (PC), using a "straight through" cable as follows (the
linked pins at the computer end are recommended but may not be necessary). The cable is
usually 9-pin at the furnace end and 9-pin at the computer, but other alternatives are shown
in parentheses.

The connection between the KD485 and the PC should be a "crossover" cable, the same as
the Furnace to PC cable in section 6.1.
