Functions and outputs

Add & Multiply functions
The MX878B currently provides the following type of
computation:
Result = a0 + a1*InputSignal1 +
a2*InputSignal2 +
a3*InputSignal1*InputSignal2
Where InputSignal1 and InputSignal2 denote the two
input signals used for this computation.
These channels will reside on other modules and must
have their isochronous IEEE1394b FireWire transfer
enabled.
Keep in mind the following notes when working with math
channels:
S The maximum sampling rate is 2400 Hz
S The sampling rate of the channel must not be higher
than the sampling rate of the input channels.
S Filters do not apply to math channels. These channels
are always unfiltered.
Matrix computation function
The MX878B The MX878B makes it possible to perform
4 parallel matrix computations each with a maximum of 6
input and output quantities and 36 constants.
Generic formula:
Fx = a1*Ufx + a2*Ufy + a3*Ufz + a4*Umx + a5*Umy +
a6*Umz
etc. for Fy, Fz, Mx, My, Mz
The ”Matrix computation” function can be used for math
ematical compensation of interdependencies (crosstalk)
of multi-component transducers for force and torque
measurement.
