Glossary
Clear to Send (CTS)
In flow control, the receiving end is ready and telling the far end to start sending.
Data Terminal Ready (DTR)
A control signal in RS-232 serial communications transmitted from data terminal equipment, such as
a computer, to data communications equipment.
Development Kit (DK)
A development platform used for application development.
Hardware Flow Control (HWFC)
A handshaking mechanism used to prevent an overflow of bytes in modems. It is utilizing two
dedicated pins on the RS-232 connector, Request to Send and Clear to Send.
Integrated Development Environment (IDE)
A software application that provides facilities for software development.
Mass Storage Device (MSD)
Any storage device that makes it possible to store and port large amounts of data in a permanent
and machine-readable fashion.
Near Field Communication (NFC)
A standards-based short-range wireless connectivity technology that enables two electronic devices
to establish communication by bringing them close to each other.
NFC-A Listen Mode
Initial mode of an NFC Forum Device when it does not generate a carrier. The device listens for the
remote field of another device. See Near Field Communication (NFC) on page 42.
Operational Amplifier (op-amp)
A high-gain voltage amplifier that has a differential input and, usually, a single output.
Receive Data (RXD)
A signal line in a serial interface that receives data from another device.
Request to Send (RTS)
In flow control, the transmitting end is ready and requesting the far end for a permission to transfer
data.
Root Mean Square (RMS)
An RMS meter calculates the equivalent direct current (DC) value of an alternating current (AC)
waveform. A true-RMS meter can accurately measure both pure waves and the more complex
nonsinusoidal waves.
SubMiniature Version A (SMA) Connector
A semi-precision coaxial RF connector for coaxial cables with a screw-type coupling mechanism.
