Serial DB25M to DB9F cable to connect HP9000 rp5470

[Finis Conner]

Hello all! I've four rp5470 and eight N4000 (aka rp7400) HP9000 servers. But only that, no cables CD etc. I just want to connect to the rp5470 with a serial cable, and don't have the A5191-63001 cable (DB25M to 3 DB9 connectors). Could somebody give me the connection diagram in order to build that cable? I can't buy the original from HP.
I've found at this forum, the following schema:
DB25M DB9F
1 GND ------------------- Shell GND
2 ------------------- 2
3 ------------------- 3
4 ------------------- 1
5,6 ------------------- 4
7 ------------------- 5
8 ------------------- 7
20 ------------------- 8,6
This is correct? What RS232 settings are needed?

The first line says "1 GND ------------------- Shell GND" This means connect the pin 1 from the DB25 to the shield of the DB9??

OK, thank you from advance!!
Regards,
Mariano

Better to use the original cable:

Well, I cannot give you the pinouts for that cable, but I can say that I have used a null-modem cable with a DB25 connector for simple console connections quite successfully.

Torsten, Robert, thank you very much for your time and answers.

I'm going to build this cable:

Further questions:
1- the shields of the DB9 and DB25 should be connected between them?

2-The settings for XP's Hyperterminal could be 9600,8,N,1,Xon-Xoff,VT100? (as there are all wires, handshake could be Hardware, I suppose)

3-The wiring for the stem intended for an UPS?

I would like to buy the original cable, but it is money for me, so I'll try to build it before.

Cheers.
