sam Posted March 9 Report Share Posted March 9 I've been trying to figure out connection details of my NI switch hardware and the connections terminal. Unfortunately I have not been able to find the answer by going thru all the provided documentations , google , and forums. The most significant information is missing from all documentation, I'm hoping someone can help me out. I've tried to ohm out man possible combinations. Questions: Question: Based on the hardware listed below, on the Terminal TBX50 (Card splits to 4 terminal blocks), which terminal pin is com0+, com0-, com8+,com8-? Question: In the Topology below, on Terminal TBX50 which pins correspond to ch0..ch31 and ch32..ch63 I have PXIe-2525 NI Switch, plus a cable that goes from the card to 4x 50-pin terminal boards (NI-TBX50). The Switch is configured as a 2-Wire Dual 32×1 Multiplexer Topology Making a Connection When using the NI 2525 as a 2-wire dual 32×1 multiplexer, the positive leads of the first bank (ch0+ through ch31+) route to com0+, and the negative leads of the first bank (ch0– through ch31–) route to com0–. The pair com0+ and com0– is addressed collectively as com0 in software. The second bank follows a similar routing scheme. Quote Link to comment
