Setting Transmit Power - TD0
Output power on the MP9310 is set by configuring the Transmit Power (TD0) register.
The output power is entered in tenths (1/10) of dBm with steps of 1/2 dBm. All values
are in decimal. Therefore, entering a value of 121 equates to 12.0 dBm. Values not
entered as 1/2 dBm steps are rounded down to the nearest valid 1/2 dBm step when the
reader updates transmit power.
For example, to set the MP9310 output power to 17.5 dBm, send the following
CHUMP command to the module:
}Cw,d:TD0,b:175!
The valid range of values for TD0 is from 0 (0 dBm) to 270 (27 dBm).
Setting Antenna Gain - TG0 (MP9310-E/EE only)
In order to comply with ERP and threshold limits according to EN 302 208, the
MP9310-E must be configured with the proper antenna gain. The TG0 register is
provided for these purposes. Before operation, the installer must know the actual
antenna gain used in the installation, G
A
.
Program the TG0 register in the following manner:
}Cw,d:TG0,b:xxx,f:1!
Where:
xxx is computed as follows: xxx = (G
A
(db) + 13.0) * 10
The range of allowable xxx is 000 through 230 which gives an allowable antenna gain
range of -13dB to +10dB. Proper LBT operation according to EN 302 208 is not
guaranteed with antennas outside of this range.
