Term
Definitions
PHY
The hardware that implements the physical layer of the OSI model. It stands between
the analog domain of the Ethernet line modulation and the digital domain of the link-
layer packet signaling.
Point of Origin
The location on the sensor from which all forces and torques are measured. Also
known as the Coordinate Frame.
Quantization
The process of converting a continuously variable sensor signal into discrete digital
values. Usually used when describing the change from one digital value to the next
increment.
RDT
Raw Data Transfer (RDT) is a fast and simple Ethernet protocol for control and data
transfer via UDP.
Resolution
The smallest change in load that can be measured. Resolution is usually much
smaller than accuracy.
Sample Rate
How fast the ADCs are sampling inside the unit.
Sensor
The component that converts the sensed load into electrical signals.
TCP
Transmission Control Protocol (TCP) is a low-level method of transmitting data over
Ethernet. TCP provides a slower, more reliable delivery of data than UDP.
Transducer
See sensor.
Txy
The resultant torque vector comprised of components Tx and Ty.
UART
Universal asynchronous receiver transmitter.
UDP
UDP (User Datagram Protocol) is a low-level method of transmitting data over
Ethernet. While UDP is faster than TCP, unlike TCP lost UDP data is not resent.
