from the master to which it is bound. The binding code defines the network, and all radios within a
network must use the same binding code.
After binding your MultiHop radios to the master radio, make note of the binding code displayed under
the
*DVCFG
>
-BIND
menu on the LCD. Knowing the binding code prevents having to re-bind all radios
if the master is ever replaced.
binding (serial
data radio
networks)
Binding the serial data radios ensures all radios within a network communicate only with the other radios
within the same network. The serial data radio master automatically generates a unique binding code
when the radio master enters binding mode. This code is transmitted to all radios within range that are
also in binding mode. After a repeater/slave is bound, the repeater/slave radio accepts data only from
the master to which it is bound. The binding code defines the network, and all radios within a network
must use the same binding code.
bit packing i/o
Bit packing uses a single register, or range of contiguous registers, to represent I/O values. This allows
you to read or write multiple I/O values with a single Modbus message.
booster (boost
voltage)
A booster is an electronic circuit that increases a battery-level voltage input (3.6V) to a sensor operating
voltage output (5 to 20 V).
CE
The CE mark on a product or machine establishes its compliance with all relevant European Union (EU)
Directives and the associated safety standards.
change of state
Change of state reporting is a report initiated by the Node when a change to the sensor’s input state is
detected. If the input does not change, nothing is reported to the Gateway.

data
channel
A channel may be either a path for communications or a range of radio frequencies used by a
transceiver during communication.
collision
A collision is a situation in which two or more transmissions are competing to communicate on a system
that can only handle one transmission at a time. This may also be referred to as a data collision.
collocated
networks
To prevent interference between collocated wireless networks, assign each wireless network a different
Network ID. The Network ID is a unique identifier assigned to each wireless network using the rotary
dials on the Gateway.
contention
architecture
Contention architecture is a wireless communication architecture that allows all network devices access
to the communications channel at the same time. This may lead to transmission collisions.
counter - event
The event counter counts the total number of times an input signal changes to the high/ON/1 state. The
counter increments on the falling edge of an input signal when the signal level crosses the threshold.
Event counters can be used to measure the total operational cycles of a spinning shaft or the total
number of items traveling down a conveyor.
counter -
frequency
The frequency counter calculates the frequency of the input signal, in Hz.
Frequency counters can be used to measure flow rates, such as measuring the flow rate of items on a
conveyor or the speed at which a windmill spins.
courtesy power
outputs
Courtesy power outputs provide continuous power and cannot be turned on or off.
cyclic reporting
Cyclic reporting is when the Gateway polls the Node at user-defined intervals.
