Analog Output with 8-Channel and 16-Channel 5B BackplanesHardware: Signal Conditioning Other>>5B Series
Problem: National Instruments sells both the 8-channel and the 16-channel version of the 5B Series backplane. How do I connect them to my data acquisition board? Solution: In both cases, you need the SC-2050 accessory to interface between your multifunction I/O (MIO) data acquisition board and your 5B Series backplane. Connect an MIO-16 board to the SC-2050 with a 50-pin ribbon cable, also known as an NB9 cable. Then connect the second output (analog I/O) from the SC-2050 to the 5B backplane using an NB7 cable. With the 16-channel backplane, you would do analog output by connecting to the analog I/O connector of the SC-2050 and placing the analog output modules in slots 14 and 15, which are routed to the two analog output channels of the MIO board. With the 8-channel backplane, however, there is no such thing as slot 14 and 15; there are only slots 0-7. To get around this, the backplane has jumpers for each slot (module) that allows you to route it to either the lower (0-7) or upper (8-15) channels of the MIO board. To do analog output, you would place the modules in slots 6 and 7 (the last two) of the backplane, and configure the jumpers to route the two channels to the upper 8 channels of the MIO board. This will effectively route them to channels 14 and 15, making it compatible with the SC-2050. The SC-205X Series User Manual has some additional information on how to connect an SC-2050 accessory to your MIO board and your 5B Series backplane.
