DI-400 Host Instruments
The following channel selection grid is typical when a single DI-725 is used with a DI-400. Note that the DI-400
channels 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 shows the channels that are still available on the host DI-400 instrument when the DI-
725 is added.
The following grid is typical of two DI-725’s used with a DI-400. Note the pattern. Each DI-725 consumes the two
highest-numbered channels on the host DI-400, 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.
