4.10.1
Network Settings
–
Network ID:
This specifies the network on which the radio operates. To communicate
to another radio, it must reside on the same network with the same network ID. Enter a
value between
1
and
4096
, in decimal format.
–
Repeaters in Network:
This feature only needs to be set in the master radio. The
repeaters and slaves within the network will automatically detect the settings.
–
Retransmit Broadcasts:
Enabling this feature forces the master radio to repeat every
packet that is to be sent by unassured (broadcast) delivery. This feature is only
available in master mode. The default is
1
.
–
Retries:
Defines the number of communication retries a frame may undergo before
being discarded. The default is
3
, and is available in slave and repeater modes. The
user may select zero to 255 tries.
–
Hop Pattern ID:
This feature is calculated directly from the network ID. If there are
multiple networks in an area, ensure that the hop patterns are not the same. If they are,
change one of the network ID numbers.
4.10.2
Radio Settings
–
Radio Mode:
Allows the user to select the radios mode of operation. Operational
modes include Master, Slave and Repeater.
–
Radio ID:
A radio identification number that identifies the radio to other radios. This
value must be unique on a given network. Enter a value between
1
and
4096
, in decimal
format.
–
Data Rate:
The over the air data rate used by the radio protocol. This feature is set to
500kbps by default and is available in all three operational modes. The user may select
between 125, 250 or 500 kbps. Decreasing the data rate decreases the channel width,
which can improve performance in noisy environments.
–
Frame Size:
The user may select between Latency, Balanced, or Throughput. Smaller
frames have less latency between each transmission and transfer less data. In
applications with high levels of interference, Latency mode may be used to hop faster.
Larger frames hop more slowly (which may be more susceptible to interference) and
send more data on each channel, which is useful for protocols that have large payloads.
This feature is set to
Latency
by default and is available in all three data rates. Latency
mode has a packet size of 110 bits, Balanced has a packet size of 264 bits and
Throughput has a size of 440 bits.
–
Roaming:
Determines whether the radio may roam to acquire any master in the
network or if a predetermined master is chosen for the slave or repeater. This feature is
set to
Yes
by default, allowing any slave or repeater to connect to any master on its
respective network.
–
Tx Power:
The transmit power of the radio. This feature is set to
+30 dBm
by default
and is available in all three operational modes. The user may select between
+10 dBm
and
+30 dBm
in 1-dBm increments.
–
Fixed Master ID:
Defines the master or repeater radio address when roaming in
disabled. This feature is disabled by default and is available in the slave and repeater
operational modes. The Fixed Master ID may be between
1
and
4094
.
–
Alternate Fixed Master ID:
Alternate masters that can specified if the master listed in
Fixed Master ID field is unavailable. If Roaming is set to “No” and the radio is unable to
link to the radio ID entered in the “Fixed Master ID” field, it will attempt to link to the radio
ID entered in the “Alternate Fixed Master ID 1” field. if the “Use Alternate Master ID”
check box is enabled. If the radio is unable to link to Alternate Fixed Master ID 1, it will
