[MCC PCI-DIO24H Product Life Cycle / Availability]

My company is using the PCI-DIO24H embedded into in-house test systems, of which we have several.

Previously we tried to use the USB-based digital IO (DIO), but the USB communication overhead made the process unacceptably slow (for example, writing a short bit stream on the PCI probably took 200-400 ms, but the USB was at least 4-5 seconds).

What is the currently product life cycle status for the PCI-DIO24H (Digilent SKU: 6069-410-080)?

Thanks,

[Product choice support: 6-8 simultaneous channel sampling, 1808X or ???]

I have tried asking this question via voicemail, email, and now this forum.

Currently have 4 systems using the analog-in sampling of the USB-2527 to capture waveforms using the APreTrig command.

New application requires a miniumum of 5 simultaneous signals to be sampled, with 2 of them differential. The waveform is roughly pulse-shaped and 500us to 1.5ms wide at the base.

It seems like the USB-1808X-OEM will work. We like the OEM version because it allows us to use the header pins to connect to a logic/glue PCB, similar to how we use the USB-2527. We like the 200kSa/s and the 18-bit may not be required, but the couple of extra bits 

Questions:

1) Are there other MCC DAQ products could be a better fit?

2) We are using the APreTrig command on the USB-2527, to get o-scope-like waveforms with pre-trigger samples. Is doesn't seem like the USB-1808 supports this command. Is there another way to obtain this behavior?

For reference, here's a snippet of the USB-2527 commands used to capture a waveform from a single channel:

===============================================================================

Allocate Memory

        MemHandleforDropPulse = cbWinBufAlloc(NumDropPulsePoints)      ' set aside memory to hold data

' Set the trigger conditions here

    ULStat = cbSetTrigger(USB_2527, TRIGABOVE, LowThresh, HiThresh)

    ' Take the scan here after the trigger conditions are met

    ULStat = cbAPretrig(USB_2527, UUTAccelNum1, UUTAccelNum1, CBPreTrigCount, CBTotalCount, CBRate, BIP5VOLTS,

MemHandleforDropPulse, Options)  //Option = BACKGROUND

    ' We will poll the status bit to see if the background scan has finished

        ErrorCode = cbGetStatus(USB_2527, Status, ScanCount, ScanIndex, AIFUNCTION)

   ' Transfer the data from the memory buffer set up by Windows to an array for use by Visual Basic

        ULStat = cbWinBufToArray(MemHandleforDropPulse, DropPulseData(0), FirstPoint, CBTotalCount)

Free Buffer at end     

        ULStat = cbWinBufFree(MemHandleforDropPulse)     ' Free up memory for use by other programs

===============================================================================

Thanks in advance
