Note that there is a spare 25 way connector in the office (if you use it please replace it!). I couldn't get it working with a 9 way.

Note: 9 way connector diagram is incorrect - pin 7 is Ground on 25 way connector, but it is pin 5 on a DB9 for ground, so it may work if DB9 pin 5 was mapped instead of DB9 pin 7

Could we update the diagram instead of just saying "diagram is incorrect" in prose later?

I was planning to delete the diagram and use the table I added instead if that is more correct, but we'll not know until we try a DB9

the 25 way and 9 way in the original table seem to view the rj45 differently, i don't think it is completely explained by the db25 being a male connector and DB9 being a female. Other than using pin 5 rather than 7 i agree the db9 matches the original manual picture, but the db25 doesn't. However the DB25 works, so that may suggest the pin numbers on the original table are right correct for an RJ45 but not for a cable as shown. If that is so, the db9 i just made will not work and needs some bits swapping.
