Modbus RS232 between Weintek LCD - Arduino

Hello

I’m trying to connect with a Weintek MT8070iH using RS232, but it seems that is necessary to buy a RS232 cable/converter or else…

Looking into http://nl.mouser.com/Search/Refine.aspx?Keyword=ST232, which ST232 you recommend to buy?
Do you have other solutions?

I’ll appreciate your help.
Thanks on advance
Best regards

Pedro Ferrer
