Mn Auto Pole – This command enables the module to automatically search for any

available IDs or Frequencies. Select ATM2 for an ID search or ATM3 for a

frequency search. For Point-to-Point search operation issue the ATD command.

For Auto Link search operation issue the ATS0=2 command. If the module finds

a valid ID (M2) or frequency (M3), the two modules will automatically connect

and display the appropriate connect result codes. After the modules disconnect the

module will then search for the next available ID or frequency as defined by the

M command. If the search began with the ATD command, you must enter another

ATD to continue the search. If the search began with the ATS0=2 command, the

module will start the search automatically. The module will search until ATS7

time has elapsed. Increasing the ATS7 time will allow for a longer search to take

place. If ATS0=2 was used the modules will continuously loop back into the

search mode until the search is stopped by either entering the either the ATS0=0

or ATM1 command.

NOTES: The Mn command will not work if Frequency hopping option enabled.

The Auto Pole option won’ t work if the modules are set to different RF Data

Rates (AT%Mn). To search for a specific range of IDs, see the AT%U command.

The Auto Pole option is invalid in Point to Multi-Point operation.

M1 Disable Auto Pole (default)

M2 Search for any available ID and connect. The module will search the AT%F

frequency for any valid ID. If the module detects a valid ID on the

frequency it is searching, the module will connect and enter the On Line

Data Mode.

M3 Search for any available frequency and connect. The module will begin

searching beginning with the frequency defined by the AT%F setting and

then search all frequencies until it either connects or times out. The modules

will only connect if a valid ID (AT%Sn) has been detected.

%Mn Select RF Data Rate – This command determines the speed of the wireless link.

Both modules must be set to the same speed.

%M0 = 76.8Kbps %M4 = 4800bps

%M1 = 38.4Kbps %M5 = 2400bps

%M2 = 19.2Kbps (default) %M6 = 1200bps

%M3 = 9600bps
