Mb star c3 customer question:

Question: What are the software do I need to operate in together with the MB Star Diagnosis C3?Thanks

Answer: You need DAS Xentry, WIS, EPC.

Question: Can you tell me with a PCMCIA adapter RS232 I can use on any laptop?

Answer: Yes, you can use it. But not Express adapter to COM. In another word, the appropriate PCMCIA to COM card is a wide 55 mm, not 30 mm.

Question: So pcmcia express does not work?

Answer: PCI express works perfect to me

Question: Does work Xentry with this card?

Answer: I usually work with Das.

But why be different ?
Usually PCMCIA REAL RS232 works fine. Express cards with prolific chipset (USB to Hub) and coresponding drivers will NOT work. If you want to use Express card one of the best chipsets and coresponding drivers is Oxford.
