National Instruments Corporation 779038-03 LFH200 to 4x50-Pin DSub Switch Cable (CH-CH Twisted),1m
- Shielded cable from LFH200 connector to unterminated wires or 50-pin D-Subs
- Twisted-pair combinations chosen to maximize signal integrity
- 50-pin D-Sub terminal blocks available from third-party vendors
- 779038-01 -- unterminated ends, 2 m, specifically suited for the PXI-2569/70/71 and SCXI-1169
- 779038-02 -- (4) 50-pin D-Subs, 1 m, specifically suited for the PXI-2569/70/71 and SCXI-1169
- 779038-03 -- (4) 50-pin D-Subs, 1 m, specifically suited for the PXI-2575 and SCXI-1175
The National Instruments LFH200 Series shielded cables provide connectivity to the NI PXI-2569, PXI-2570, PXI-2571, PXI-2575, SCXI-1169, and SCXI-1175 switch modules. There are three different versions of this cable. The first (779038-01) has unterminated ends for custom wiring needs, twisting the channel and common terminals of the PXI-2569 and SCXI-1169 to reduce crosstalk. The second (779038-02) uses the same twisted-pair configuration but offers 50-pin D-Sub connectivity. The third (779038-03) offers 50-pin D-Sub connectivity but twists the ch+ and ch- terminals of the PXI-2575 and SCXI-1175 when used in a 2-wire configuration. This feature makes it uniquely suited for that particular switch module. For more information, read the LFH200 Cable Installation Instructions.
