Local Node
nodeid

Each radio in a network must have a unique Node ID.
Valid values:
Slave: 1-‐254
Master: 1-‐199
Repeater: 200-‐254
Network Key
key
[1-‐254].[0-‐255]
All units in a network must have the same user
selected 'Network Key' in order to communicate. Key
format is "AAA.BBB". The first number (AAA) is an
number from 1 to 254 and may not be 64, 128, or
192. The second number (BBB) is a number from 0 to
255.
If two separate networks will be operating in close
proximity, it is important that they each have a
different Network Key.
Upstream Node upstreamnode
0-‐255
*Only available in firmware 2.01s and later
For slaves and repeaters only. Specifies a specific
node number (of a master or repeater) to link to. If
set to 255, the node will link to the first master or
repeater radio that it hears. If link is lost, the radio
may change which node it is linked to. If set to 0, the
radio will link to the first master that it hears and will
not link to a repeater. With a value of 1-‐254 the node
will only link to a radio with the specified node
number.
