%Sn Select Channel ID – Use this command to choose one of the available 256

Channel IDs that you want to use to communicate. To communicate with one of

more remote modules, they must all use the same unique Channel Id Number.

The channel range is between 0 and 255. The default is Channel 255. The

command format is as follows:

AT%S132<CR> Select Channel 132

OK Channel Selection OK

%Un Search for a specific range of IDs and Connect – This feature uses the AT%Sn

and AT%Un commands to define a specific range of IDs for the module to search

for and connect to. In order for the search and connect feature to work, the

modules frequency (AT%Fn) and speed (AT%Mn) must be the same.

Example: To search for any valid IDs between 24 and 32, enter AT%S24 and then

AT%U32. For Point-to-Point search operation issue the ATD command. For Auto

Link search operation issue the ATS0=2 command. The search would begin with

ID 24 and end with ID 32. If any valid ID is found, the module would connect,

display the appropriate result codes and enter the On Line Data Mode. After the

module disconnects, the module will then search for the next ID in the specified

range. The module will only search for Valid IDs in the range defined by the

AT%Sn and AT%Un commands. To disable this search mode enter AT%U255

(default) and set AT%Sn to the ID of choice. See the ATMn Auto Pole option for

additional information on ID searching.

Vn Result code form

V0 Enables short-form (terse) result codes.

V1 Enables long-form (verbose) result codes (default).

See the Command Result Code section for a list of available result codes.
