Just wanted to give an update and thanks for all the info here and across the board.
Turns out the default on my unit is 300 7D 2S / 300 7-N-2 with XON/XOFF and the pins for the adapter are green 2, red 3, yellow 5.
Using the Hyperterminal trial for Windows 10, I was able to make the connection. I almost didn't notice it because I didn't realize that I needed to hit return once I connected before anything showed up on the screen.
