10.4 MX879B Multi‐I/O module
The MX879B module is a multi-I/O module with eight
analog outputs and 32 digital I/Os that can be accessed
on the front panel via plug terminals.

Two analog outputs each (1 and 2, 3 and 4, etc.) have
the same ground potentials, for the others electrical isola
tion applies between them and the voltage supply
ground.
The modules can receive all signals that are isochron
ously available on the IEEE1394b FireWire.
The settings for this are implemented with the QuantumX
Assistant. Before output at the analog output, the signal
passes through an output characteristic curve parameter
ized by the user (2-point scaling) and a filter also para
meterized by the user. In addition, the rate for DAC is
reduced to 96 kS/s through interpolation.
The MX879B functions are similar to those of the
MX878B.
In addition, the MX879B offers a limit value monitoring
function.
