Command identifier 'p': Change transmitting power
Setting the transmitting power (ERP/EIRP) as ¼-dBm
value. The transmitting power influences the maximum
range of the detection range of the antenna.
Example:
Set a transmitting power of 23 dBm (200 mW):
23 dBm
=92
¼ dBm
92 = 5C
hex
The following values must be transferred for this purpose:
– Transmitting power 1st character: '5'
– Transmitting power 2nd character: 'C'
The maximum permissible transmitting power
depends on the antenna used and on the radio
regulations applicable in the respective country. For
detailed information, see chapter 5 on page 18
and the data sheet of the antenna used.
