WAGO-I/O-SYSTEM 750
®
750-644 Bluetooth RF-Transceiver
EIRP
(Equivalent isotropically radiated power)
Product of the radiated power passed to a transmitting antenna multiplied by the
antenna gain.
Encryption
Encryption converts sensitive data to illegible/unusable data by using a key. The
raw data can only be obtained from encrypted data if the key is known.
F
FCC
(Federal Communications Commission)
Approval authority for communications devices in the USA
Firmware
For this I/O module: Software of the microcontroller used. The following versions
can be queried separately: host controller and baseband controller.
Flag
An indicator for identifying certain conditions. A flag is represented by one bit.
A certain status is represented by a certain bit value.
Fresnel zone
Predictable spatial regions between the transmitting and receiving antenna for a
radio transmission.
Function block
Function blocks are used for IEC-61131 programming and stored in libraries for
repeated utilization. A function block is a structured module, which has a name
and contains input and output variables, but also local variables.
H
HCI
(Host Controller Interface)
An interface in the Bluetooth
directly act on the baseband protocol.
Hexadecimal
In a hexadecimal numbering system, the numbers are represented in a base 16
place value system.
Host controller
Host controllers are microcontrollers with different software statuses that can be
queried.
