7.6 TEDS transducers

7.6.1 TEDS connection

TEDS stands for "Transducer Electronic Data Sheet". Transducers with an
electronic data sheet as defined in the IEEE 1451.4 standard can be connec-
ted to the PMX system, making it possible for the amplifier to be set up auto-
matically. A suitably equipped amplifier imports the transducer characteristics
(electronic data sheet), translates them into its own settings and measure-
ment can then start.

The IEEE standard 1451.4 defines a generally acknowledged process with
which sensors can be identified. The sensor is identified by its respective data
sheet, which is stored in electronic form in the sensor, in the cable, or in the
plug, on an EEPROM. The amplifier communicates with this EEPROM via the
serial interface, reads the data sheet and makes the corresponding amplifier
settings.

7.6.2 Starting up the TEDS module

Sensors can be fitted with TEDS at the factory and delivered in the written
state.
TEDS modules that are already mounted in the plug can be subsequently
configured and parameterized with a TEDS dongle (1−TEDS−DONGLE) and
a TEDS Editor. The relevant connector is plugged into the RJ45 socket of the
TEDS dongle.
