2 Setting up a system
MX Modules A04089_07_E00_02 HBM: public 35
(TEDS - Transducer Electronic Data Sheet). The amplifier communicates with this
EEPROM via the serial 1-wire interface, reads the data sheet and makes the
corresponding amplifier settings.
HBM recommends the TEDS chip (1-wire® EEPROM) DS24B33 from Maxim. HBM
offers a package with 10 TEDS (1-TEDS-PAK).
2.8 Digitalization and signal path
Each SomatXR measurement channel generates two signals. These signals can be
individually parameterized with a different data rate and filter. Parameterization is
easiest to implement with the MX Assistant software.
If several modules are connected together via FireWire, signals can be sent in real
time (isochronous), e.g. from signal source to an output (analog, CAN or Industrial
Ethernet: EtherCAT® or PROFINET). This isochronous real time operation is
possible in parallel to the asynchronous operation. The maximum data rate here is
4.8 kHz.
SomatXR Rugged DAQ supports the following types of scaling:
n Two points (y=mx+b)
n Table (multi-points) supported only from MX840B-R, MX411B-R and MX460B-R
n Polynomial supported only from MX840B-R, MX411B-R and MX460B-R
