Transducer connection

7.1 Connector concept

7.1.1 TEDS module

The IEEE standard 1451.4 defines a generally acknowledged process with
which sensors can be identified. The sensor is identified via the respective
data sheet which is stored in electronic format in the sensor, cable or plug on
a 1-wire EEPROM (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.
The TEDS module that HBM provides under the 1-TEDS-BOARD product
number can, for example, be fitted in a field-assembled, (espressoDAQ) RJ45
connector (insulation displacement connection).

7.1.2 Installing the TEDS module in the RJ45 connector (tool-free fitting)

The RJ45 connector (IP20) product no. 1-RJ45-EMV is a field-assembled
connector, in which the cable is fitted tool-free, by means of an insulation dis-
placement connection. The TEDS module has deliberately been equipped
with two insulated wires for this. There are two steps to the open plug fitting:
1. Engage the module in the relevant pins of the RJ45 connector,
as shown in the table.
