4.0 Register/Command Reference
&W Write Configuration to Memory
&V View Configuration
Displays S Register names and current values.
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)
Image 4-3: Restricted Bands
&H0 Frequency Restriction (continued)
2410.00 was entered as the ‘start’ and ‘end’ of Band 1; this will restrict the frequency of 2410.00MHz.
The range of 2417.50 to 2420.00 MHz was defined as the second (Band 2) restriction. When prompted
to enter Band 3, the [Esc] key was entered to escape the entry process and the summary at left/bottom
was displayed. Pressing [Esc] again saves and exits the process. To modify an existing restriction,
simply overwrite it. To remove a restriction, overwrite it with 000.000.
&H1 Repeater Registration
When more than one Repeater exists in a network, the Unit Address of each Repeater should be
registered within
every
modem
in the network. The reason for doing this is to enable the modems to
create hopping patterns which will be orthogonal to each other, thereby minimizing possible interference
between network segments.
Upon entering the AT&H1 command, the modem prompts as follows:
A
to add a Repeater (this is done by entering the Unit Address of the Repeater)
R
to remove a Repeater
C
to clear all registered Repeaters.
Pressing the [Esc] key saves and exits the process.
