Config words are used to enable/disable 192 kHz macro channels authorized for transmission.

Each macro channel is separated from another of 300 kHz. At least 9 macro channels must be enabled to ensure the

minimum of 50 FCC channels (9 * 6 = 54). This function should be called each time you open the library, or your FCC

configuration will not be applied.

Example: To enable Macro channel 1 to 9, that is to say 902.2 MHz to 904.8 MHz with 902.2 MHz as the main macro

channel, you must set:

config_words[0] = [0x000001FF]

config_words[1] = [0x00000000]

config_words[2] = [0x00000000]

7.2.1.3 Update PA curve

The current firmware supports the update of the output power amplitude curve for ramp-

up and ramp-down functions:

1. Type

25 to select Update PA Curve command, and then press Enter.

2. Type

1 to update ETSI PA curve or type 4 to update FCC PA curve (for RCZ2/4), and

then press Enter.

3. Type the new values and press Enter after each new value. (To keep default value at

the current index, just press Enter without entering a value. 86 values are needed for

FCC table and 200 values are needed for ETSI table. After entering the last values

and pressing Enter, the table will be updated with the new values, as shown in the

following figure)

4. To confirm the update of the PA curve, read the current updated PA curve by typing

25, then press Enter. Type 0 (for ETSI table) or type 3 (for FCC table), then press

Enter. The first 3 bytes of the RX frame contain the frame length, error code and

OL2385 state in order. The next 200 bytes contain the 200 updated PA curve values

for ETSI. In case of FCC, only the next 86 values are valid out of the 200 values

shown (as shown in the following figure)
