Correct the pin mapping information for the 9 way connector.
Corrected the description of the ground pin for the 9 way connector and added pin mapping tables for DB25 and DB9 connectors.
Corrected the spelling of 'digram' to 'diagram' in the note about the 9 way connector.

| 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

If db9 works remove db25 table too

given its in version control i'll delete diagram now

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.
Corrected pinout information for DB25 and DB9 connectors in the TDK-Lambda-Genesys documentation.
Corrected connector descriptions and added details for DB9 and RJ45 pin mappings.
Updated wiring instructions and corrected connector pinout information for TDK-Lambda Genesys power supplies.

| from TDK Manual (note: TDK manual pinout for the 8 pin connector side is reverse of RJ45, they are correct for RJ45 below where looking into the RJ45 socket with the connectors at the top pin 1 is on the left) | ||

might be worth running prettier on this file (or any other formatting tool) as it makes tables nicer to read in markdown - just did this for #162

I'm not sure if there is a "Standard" mapping of RS232 connectors DCE/DTE to RJ45 connectors - i.e. did TDK use this. I've always treated the MOXA RJ45 cables as a useful local standard for us as they end up with the right DB9/DB25 connectors DCE/DTE one way or another! I would be curious to know if a 9-way worked with the 25-way left in place, but then adapted via a standard straight through 9-25 way adapter or similar gender changed 9-25way? This would probably point to a DCE/DTE difference in the RJ45 pins (for identical sockets!)
