PXI-2593 or SCXI-1193 Does Not Make Connections but Gives No Errors Hardware: Switches>>Multiplexer/Matrix>>PXI-2593
Problem: When I run a program that uses my PXI-2593 or SCXI-1193, everything seems to run fine with no errors. However, when I check my connections for continuity, the connections are not made. Why is there such a discrepancy? Solution: There is a ribbon cable on the PXI-2593 which connects the switch's motherboard and daughterboard together. On the SCXI-1193 there is two ribbon cables which connect the motherboard to the two daughterboards. Sometimes these cables get jarred loose when the board is handled. When these cables are disconnected, the behavior mentioned above occurs. Verify that the ribbon cables between the motherboard and daughterboards are secured by the cable latches. The motherboard handles the software switch commands and then passes the commands to the daugtherboard, which houses the physical switches. Therefore when these ribbon cables become loose the switch commands are executed in software without any errors, but switches do not physically connect. Make sure power is off before attempting to reconnect a ribbon cable. Related Links: Product Page: PXI-2593 Product Page: SCXI-1193 Attachments:
