PCI-1424- Different Part Numbers?

[Nichole]

Hello,

This is my first post on NI's forum. We have several PCI-1424 boards that we purchased. We thought they were the correct boards; however, we later realized that there is more than one part number for the PCI-1424 and we had purchased the wrong ones. What are the differences between the part numbers? If anyone could help me out, I would greatly appreciate it.

Thank you!

I do not fully understand your question.  The PCI-1424 is the part number for that specific product.  You want to know the differences between part numbers, but you only list 1 part number.  Below are links to NI product pages that should help with your questions.  But it might be easier to call NI and explain what your needs are and they can recommend a specific device for your needs.

You could also try asking your question in the machine vision forum instead of the Digital IO forum.

I apologize for the confusion. The PCI-1424 has the following model numbers: 777662-01 and 777662-02. I did not realize that there was more than one model for the PCI-1424 before purchasing.

I found these links using google.

4. Signal Types

There are four types of digital signals used to send the image data to your image acquisition device.

• TTL is a single-ended, 0 to 5 V signal. It can travel only about 1 meter (6-8 feet) reliably. Due to the large voltage swing, the signal cannot maintain pixel clock frequencies above 20 MHz. TTL signals are not as common because of these limitations.
• RS-422 is a differential signal that can travel about 6-8 meters (18-24 feet). It has the limitation of 20 MHz maximum for the pixel clock. This type of signal is typically used for digital cameras that do not require pixel clocks faster than 20 MHz.
• LVDS (Low Voltage Differential Signal) is a differential signal with a lower voltage swing. The differential property allows for 6-8 meters (18-24 feet) of digital data integrity, and the lower voltage swing allows the signals to have greater than 20 MHz frequencies. Cameras that require faster pixel clocks use LVDS signals.
• Camera Link is a new digital standard that sends back serialized data instead of parallel. All bits pass through a converter onboard the camera, which places all of the data on a single line. The device then sends this single line back through a converter to return the data to the camera. This standard allows for thinner cables and uses a standard connector. The Camera Link standard can support pixel clocks greater than 20 MHz and can travel up to 10 meters (30 feet). Camera Link's enable lines use the LVDS signal. Camera Link eliminates the burden of specialty cables, since the Camera Link cable is compatible with every Camera Link camera and image acquisition device.

The table below lists the boards that support the four digital formats.

Note: The IMAQ 1424 and 1422 Series devices each have a RS-422 and LVDS version. 

IMAQ PCI/PXI-1422 
RS-422 777959-01
LVDS 777959-02

IMAQ PCI/PXI-1424
RS-422/TTL 777662-01
LVDS/TTL 777662-02

IMAQ PCI-1428
Camera Link 777315-01

That helps a lot. Thank you!
