Values
&Fn Load Factory Default Configuration
Loading Factory Default settings allow for quick configuration of systems
by setting a known starting point with factory recommended settings for
each type of unit. The Factory settings change all settings required to
initiate default communication with other unit types.

&W Write Configuration to Memory
&V View Configuration
Displays S Register names and current values. AT&V1 displays a complete set of user parameters for advance
users.
Stores active configuration into the modem’s non-volatile memory. Any changes made to the Pico Series must be
written to NVRAM using the AT&W command (AT&WA will write the changes & set unit in online mode)
Mesh Primary Coordinator - Each Mesh network must have a primary
coordinator. The primary coordinator provides the synchronization for the
network.
Mesh Secondary Coordinator - Secondary coordinators can be deployed
to extend the range of the Mesh network. Each device on a Mesh network
must have LOS (Line of Sight) with either a Primary or Secondary
Coordinator.
Mesh Remote (Slave) - Any device on the network that is not a Primary or
Secondary Coordinator, generally attached to end devices. Can also be
used to perform routing tasks if enabled.
Master (PMP/PP) - Only one per network. In PP/PMP network types (see S133) data either originates at, is destined
to, or passes through the Master.
Repeater (PMP/PP) - May act simply as a ‘Repeater’ to store and forward data to/from an upstream unit to/from a
downstream unit (e.g. when there is a long distance between units), or, may act as a Repeater/Slave in which case
the above function is performed AND the unit may also exchange data as a Slave within the network.
Slave (PMP/PP) - Interfaces with remote devices and communicates with Master either directly or via Repeater(s).
N Advanced Spectrum Analyzer
The Advanced Spectrum Analyzer feature provides for a very detailed analysis of a particular area of the radio
frequency spectrum within which the P900 operates.
The specific start (of scan) and stop frequencies, along with step (increment) size and dwell (on frequency) time are
user-definable.
Following is the format for the ATN command:
In Command Mode
ATN F
start
F
stop
S D[Enter]
where
F
start
= start frequency in MHz (including 0-6 decimal places)
F
stop
= stop frequency in MHz (including 0-6 decimal places)
S = step increment in kHz (from 1-1000)
D = dwell time in ms (from 1-1000)
Example:
ATN 905.250 908.500750 25 100
Note: Be sure to enter spaces as shown in the format detailed above. Use ATN /? For help.
