REG09 (frequency 3)
[Default: 4DH]
This register defines the frequency channel to be used for radio communication. The frequency channel
that is set by this register is applied only if the RGE06 setting is 03H.
The range of the setting is 2,402 MHz to 2477 MHz. It is possible to set it by both 2-digital hexadecimal
value (02H to 4DH) and 3-digit decimal value (002 to 077). For more details of correspondence between
setting values and frequency channels, please refer section 5.1. FDP03 returns N0 response if the value is
out of the range.
REG10 (Data Transfer)
[Default: 01H]
Bit 7 and 6: Not used
Bit 5: Data transfer mode
0
Interchange mode (default)
1
Communication Distance Extend mode
The data transfer mode should be same setting among communication
partners. If the mode is different each other, it is impossible to
communicate with.
Bit 4 to 0: Not used
REG11 (retransmission count)
[Default: 0AH]
This register defines the maximum frequency of data packet retransmission.
When the sender FDP03 cannot receive ACK signal from the receiver FDP03, it retransmits the data packet
"'defined value of this register' +1" times.
At broadcast transmission mode, the sender FDP03 always sends the data packet "'defined value of this
register' +1" times.
The enable setting range of this register is 00H to FFH (0 to 255 times). FDP03 returns N0 response if the
value is out of the range.
REG12 (unused)
[Default: 00H]
This register is not used. It should be default setting “00H”.
