DI–720/DI–722/DI–730 Series User ManualAccessories51DI-730 Host InstrumentsThe following channel selection grid is typical when a single DI-725 is used with a DI-730. Note that the DI-730channels are enabled on the top row of the grid and the DI-725 channels are enabled on the row labeled “MUX A”.The shaded area on the top row of the grid shows the channels that are still available on the host DI-730 instrumentwhen the DI-725 is added.The following grid is typical of two DI-725’ s used with a DI-730. Note the pattern. Each DI-725 consumes the twohighest-numbered channels on the host DI-730, and the expansion channels are enabled on the next MUX row down.The result is similar when more DI-725’s are added to the system.When a Single DI-725 is Used.These 8channels arestill available onthe host DI-730.A AThese are the32 DI-725expansionchannels(enable themon this row).These 2 channels areconsumed by the DI-725.When Two DI-725’s are Used.These 8channels arestill available onthe host DI-730.A AThese are the32 expansionchannels on thefirst DI-725(the one directlyconnected tothe DI-730).Enable them onthis row.These 4 channels are consumed bythe DI-725’s.B BThese are the next 32 expansionchannels on the second DI-725 (theone not directly connected to the DI-730).
