2.10 DaisyMux Operation
DaisyMux is a special operation mode where all of the signals are shared between 2 or more
multiplexers. The MultiMux supports up to 8 multiplexers used in a DaisyMux configuration and the
switching mode is ALWAYS 16 Channel.
The advantage with the DaisyMux configuration is that a single cable may be used to connect a string of
MultiMux multiplexers together, as shown in the diagram below.
There are 2 configuration issues to deploy the DaisyMux, the DIP switch settings of the MultiMux and the
MultiLogger Software configuration.
MultiMux DIP Switch Settings
On the MultiMux are 3 switches in the DIP switch array, labeled A2, A1 and A0, that control the address
of the multiplexer, this address ranges between 0 and 7 in binary values, or between 1 and 8 in terms of
the multiplexer number. These determine which section of channels will be activated, i.e. the MultiMux
configured with address 0 with be active for channels 1-16, the MultiMux with address 1 will be active for
channels 17-33, etc.
The following table illustrates the range multiplexer numbers and corresponding DIP switch settings.
