Top Reasons to Get MB Star SD C4C5 and Laptop Full Package

Here list reasons why you should buy a Mercedes Benz MB Star diagnostic tool with a laptop full package:

—With the Dell D630’s dedicated serial port, there was no issue for me…. it was plug and play… I just loaded the HDD from the Seller into my Dell and all I needed to do was activate WIS/EPC and XENTRY/DAS with “activation keys”… I only use the Dell for mb star sd c4 purposes…

—Bought an older Dell D630 laptop with a serial port and plan on buying MB SD Connect C4 directly installed in a Dell D630 hard drive. No Virtual Machine issues.

Mercedes Benz Star diagnosis C3 / C4 actually specifies the computer or tablet used in the SDS environment… The T30 is rather slow but will get the job done.

—If your ever in the market for a faster SDS laptop, the Dell D630 with at least 2Ghz and the speed improvement especially when using Xentry is like night and day.

—the HDD that is pre-loaded with the software for SD Connect 4 by the Seller, is inserted into the DELL D630… The DELL D630 is the fastest laptop with the RS232 feature.

—Need to connect directly into a RS232 port without using an interface – this is why I went for the complete system with laptop.

—The software Xentry/ DAS is a bit slow on an old IBM so that it is worth paying a bit extra and getting a Dell D630.

—There is a very specific set of COM ports you must use for it to work. For example you need DAS to be looking at COMx within the VM session, then VMware needs to redirect that to COMx which is a ‘physical’ serial port on your machine.

—It’s probably because it has a real com port. Most laptops these days have just a USB port and things don’t always work right if you’re using a USB to RS-232 converter. You wouldn’t want to brick a component during an update if you’re using USB. The other option would be to get a Mb Star C4 system, but then they cost more. I think there are a couple other systems out there like IBM that also have real com ports.

—The PART D mux(C3) is a serial ported mux—that’s the reason for the Dell and IBM older laptops.

—The PART W mux(SD connect C4) is and Ethernet/wifi connected system and that is the reason for use on other laptops—the issue is the operating system currently DAS Xentry only runs on XP.

—Plug and play!! It is more convenient for users because the software for C3/SD C4 diagnostic tool will be pre-installed before delivery.

Note that the computer consumes electricity even when the computer power is

off. If the battery pack is fully charged, the battery will fully discharge in the followingperiod of time:

1.When power is off: Approx. 9 weeks
2.In sleep ( )/standby ( ): Approx. 4 days
3.In hibernation: Approx. 8 days

If “Wake Up from LAN” is disabled, the period of time in sleep will become

slightly longer, and the period of time in hibernation will become about the same as during power-off.

When the DC plug is not connected to the computer, disconnect the AC cord from CnAutotool wall outlet. Power is consumed simply by having the AC adaptor plugged into an electrical outlet.
