Hello,
I am having problems how to configure “DS_C232HM_MPSSE_CABLE”.
- I have downloaded the “CDM 2.08.30 WHQL Certified” driver and installed it on an XP PC.
- “Load VCP” is unchecked
- downloaded the labview drivers and the i2c wrapper
When I run I2C_Open_Device.vi I get the screen below, handle is NULL so no device is found.
I have also programmed the EEPROM with the utility FT prog.
What am I doing wrong or what am I forgetting?

you do need to expose the device as a VCP (Virtual Com Port) the FTDI drivers are found here. http://www.ftdichip.com/FTDrivers.htm
Or use the installer that came with the device (You may need to run the installer twice. trust me you may)

Hi Jeff,
I did it a couple of times instlling the drivers but no succes.
First how do I have to program the EEPROM, or leave it blank?
Second what are the differences between the MPSSE and FTCI2C both are mentioned on the FTDI site but it's not clear.
I used FTCI2C with the labview examples.

Hello dakxceed,
Are the LabVIEW examples you're referring to examples provided by FTDI on the following page?
http://www.ftdichip.com/Support/SoftwareExamples/CodeExamples/LabVIEW.htm
If yes, then you should for sure also install the D2XX drivers.
Did you do this?
Do you see the COM-port in NI MAX (as described in the KB below)?
http://digital.ni.com/public.nsf/allkb/8D86BCD37B16697D8625739C0037A933?OpenDocument
Concerning both questions I think it might be best to contact FTDI.
They are in the best position to explain all the differences.

Hello Fredrick,
What issues are you exactly encountering?

Hi,
The examples for LabVIEW from FTDI is made using the D2XX drivers ( .dll files ). I have programmed the device to enumerate as Virtual COM port and it is visible in the devicce manager also but I cannot find any kind of read or write operation occuring between my FTDI chip and the EEPROM ( I2C).
I am guessing there might be issues in the configuration settings of VCOM migh be wrong and I tried by trails using multiple options of changing the baud rates, stop bits, flow control etc .. but nothing of this worked out to my application. If anyone can share the steps involved in setting the VISA test panel configuration kindly share it.

There is the driver you are looking for. I2C driver Labview:
