Connecting Four Multiplexers to CellScale (Two A/D inputs required)

A single CellScale can control, at most, four Multiplexers. The primary Multiplexers will connect directly to the two load
cell inputs on the CellScale, typically as channel 1 and channel 3. The secondary Multiplexers will connect to the pass
thru of the primary Multiplexers, then to the inputs on the CellScale, typically as channel 2 and 4. The following diagram
illustrates this.

For information about how to setup the CellScale scan list for this configuration, see the “ Software Setup” section.

Software Setup

For details of operating the CellScale software, please reference the CellScale owner’s manual in addition to the content
provided here.

Connecting One Multiplexer To CellScale

When connecting a single Multiplexer to a CellScale, the load cell’s attached to the Multiplexer will be entered in the
CellScale scan list as 1-X, where X corresponds to the labeled input on the Multiplexer. The ninth load cell input (if used)

will be entered into the CellScale scan list as channel 2-1. An example scan list is shown below.

For details about connecting the hardware for this configuration, see the “CellScale Connections” section.
