determinism
A deterministic system defines how network endpoints behave during the loss of communications. The
network identifies when the communications link is lost and sets relevant outputs to user-defined
conditions. Once the radio signal is re-established, the network returns to normal operation.
device, node, or
radio address/ID
(DX80
Networks)
The Node address is a unique identifier for each wireless device on a network and is set using the rotary
dials. For the DX80 networks, Gateways are identified as device 0. Nodes are assigned addresses
(NADR) from 01 to 47 using the rotary dials.
directional
antenna
A direction antenna, or Yagi, is an antenna that focuses the majority of the signal energy in one specific
direction.
Direct Sequence
Spread
Spectrum
(DSSS)
Direct Sequence Spread Spectrum is a method for generating spread spectrum transmissions where the
transmitted signal is sent at a much higher frequency than the original signal, spreading the energy over
a much wider band. The receiver is able to de-spread the transmission and filter the original message.
DSSS is useful for sending large amounts of data in low to medium interference environments.

DX83 Ethernet
Bridge
The Ethernet Bridge acts as a communications bridge between the Modbus RTU network (Gateway)
and Modbus/TCP or EtherNet/IP host systems and includes the ability to configure the network using a
Web browser interface.
effective
isotropic
radiated power
(EIRP)
The EIRP is the effective power found in the main lobe of a transmitter antenna, relative to a 0 dB
radiator. EIRP is usually equal to the antenna gain (in dBi) plus the power into that antenna (in dBm).
Ethernet
Ethernet is an access method for computer network (Local Area Networks) communications, defined by
IEEE as the 802 standard.
EtherNet/IP
™
EtherNet/IP is Allen-Bradley’s DeviceNet running over Ethernet hardware.
extended
address mode
Using extended address mode isolates networks from one another by assigning a unique code, the
extended address code, to all devices in a particular network. Only devices sharing the extended
address code can exchange data. The extended address code is derived from the Gateway's serial
number, but the code can be customized using the manual binding procedure.
flash pattern
Flash patterns are established by selecting timeslots to turn the output on or off. While originally the
flash pattern was designed to turn on and off an indicator light, the flash pattern can be set for any
discrete output or switch power output.
FlexPower
Banner’s
Flex
Power
®
technology allows for a true wireless solution by allowing the device to operate
using either 10 to 30 V DC, 3.6 V lithium D cell batteries, or solar power. This unique power
management system can operate a
Flex
Power Node and an optimized sensing device for up to 5 years
on a single lithium D cell.
