My kit came with 2 adapters, and a blue straight through cat5.
Adapter #1 is a 180-0055 only has 3 wires connected. rx/tx crossed over:
DB9 Pin 2 = RX <---> RJ45 Pin3
DB9 Pin 3 = TX <---> RJ45 Pin2
DB9 Pin 5 = GND <---> RJ45 Pin5
Adapter #2 is a 180-0059, has 3 wires to the serial port, appears to be straight through
DB9 Pin 2 = RX <---> RJ45 Pin2
DB9 Pin 3 = TX <---> RJ45 Pin3
DB9 Pin 5 = GND <---> RJ45 Pin5
Pictures below are what I used for referencing location of PIN 1 only on the DB9 male and RJ45 female, the pin out labels included in these pictures are not for this application, that's what the text above is for.
