The title implies that you have a DB9 connector(s). So you have a cable? If not, then are the pins on the tractor make or female?
Could you explain what columns in that chart are for? Is it: Antenna, Signal Name, DB9_A, DB9_B, Deutch Connector??
The only signals you should need from that list are RX, TX, SIG GND
RS232 implies higher voltage than you should be feeding Reach, so a RS232 to UART (3.3V) adapter is required.
