HP powertrust ups serial connection

Hi

I have recently been given a HP Powertrust A2994A ups, built like a tank and quite old but should serve me well.

 

However I cannot get HP Power Manger to connect with it. After a lot of time trawling the net I have been unable to find either a manual or the serial port pin outs as I gather these are non standard serial cables.

 

Has anybody got a copy of the manual or know what the pin out should be.

 

Many thanks

David

Re: HP powertrust ups serial connection

hi,

 

What do you want to connect to it? If You want to connect it to a D-series, you should use 5061-2575, which is a
9 pin female to 9pin male.

 

Thanks !

There are 2 cables listed:

5061-2575 RS-232 cable, DB9 9-pin male/DB9 9-pin female (2.5 meter)

5061-2569 RS-232 cable, DB9 9-pin male/DB25 25-pin male (2.5 meter)

Hope this helps!
Regards
Torsten.

Re: HP powertrust ups serial connection

Many thanks to both of you for your swift responses.

 

That confirms the cable I need however they are not that commen or easy to get hold of.

 

So I thought I would make up my own thats the reason I want to know the pin out.

 

I will be connecting to a windows server so it will be db9 male to db9 female.
