The power is set with the command:
| AT S160=n<CR><LF> |
Where: | sets the power threshold <1 to 10> |
Default: | 10 |
Read | AT S160?<CR><LF> |
Read Return: | nn<CR><LF> |
Example: | AT |
4.15Channel Step Size (AT S161)
This command sets the channel step size. The basic reference frequency for the radio is either 12.5KHz or 10KHz, giving possible frequency channel steps of 10kHz, 12.5kHz, 20kHz and 25kHz. The Channel Step Size is set with the command:
| AT S161=n<CR><LF> |
Where: | n=1 10 kHz |
| n=2 12.5 kHz |
| n=3 20 kHz |
| n=4 25 kHz |
Default: | n=2 (12.5 kHz) |
Read: | AT S161?<CR><LF> |
Read Return: | n<CR><LF> |
Example: | AT S161=1<CR><LF> sets 10 kHz channel step |
If a channel step size is entered which is not a multiple of the centre frequency an error is returned and the entry ignored. This is to ensure that only valid frequencies on multiples of the channel step size are allowed based on the centre frequency entered. The error message is of the form:
ERROR<CR><LF>
4.16Test Message Period (AT S162)
This command sets the period between sending the test message. The command is:
| AT S162=n<CR><LF> |
|
Where: | n=1 - 255 in 10ms steps |
|
Default: | n=10 (100ms) |
|
Read: | AT S162?<CR><LF> |
|
Read Return: | nnn<CR><LF> |
|
Example: | AT S162=100<CR><LF> | sets 1 second period |
