How to tighten a connection that uses SH68-68-EP?

[Christ0phe]

Hello,

I need to connect my PCI6023E/MIO 16E-4 to a 5B backplane. I have already got the 50F-26F cable (180555-10) and the 68F-50M adaptor (183139B-01). Now I need to connect to my PCI card (68M). Thatfore I have purchased a SH68-68-EP (68F-68F) and also a 68M-68M SCSI cable. To tighten the 68F-68M connection, small screws are needed so that both connectors can be screwed together to these screw. These screws (M2 probably) are hard to find (because the available M2 are not thick enough) and I was wondering if someone had an alternate solution ?

Thanks,
Christophe

Hello Chris,

Following the 1999 National Instruments Catalog you only need for direct connection between a E-Series PCI DAQ board and the 5B series signal conditioning the 68F-50M MIO adapter (183139-01) and the NB9 cable (180555-10, what you call the 50F-26F cable).  So, this is exactly what you already have.

But I am wondering: are you using the SH68-68-EP cable to extend the distance between the DAQ board and the 5B backplane?
If this is the case, I can recommend to use the SH6850 cable. Available till 10 meters.  This is a specific cable to connect a PCI DAQ board to a 50 pin accessory.  Only problem here is that the 50-pin side of this connector is female.  Also the NB9 cable to connect to the 5B Backplane is female, so you will need to find a 50 pin male to 50-pin male header adapter.  As far as I know this is not available at National Instruments.  No screws involved in this case.

A question from my side.  Why are you using 5B signal conditioning.  This is pretty old technology.  National Instruments has now new state of the art DAQ boards with integrated isolation or even better: their Compact DAQ platform.  This is a USB DAQ platform with configurable I/O modules.

Best regards.
