rs232 cable between lockin SR830 and PC

Hi,

I have an lock-in Amplifier SR830 and I need to read data from SR830 (DCE, db25) to computer (DTE, db9).

I read the manual of lock-in and another tutorials, but can not understand, because I do not have experience this.

Please, I would like of an exemplo which show me how I can do a cable: SR830 (DCE, db25) <-> computer (DTE, db9).

Thanks any infor.
Acosta.
