•
Enable/disable reception of broadcast transmission in packet transmission mode
(Mode 3 and 5).
Bit 4: Antenna selection
0 Antenna is fixed to A (default value)
1 Antenna is fixed to B
Table 5–8: Antenna Selection
• At the non-diversity reception, decide the antenna terminal.
Bit 3: Extended reception
0 Disable extended reception (default value)
1 Enable extended reception
Table 5–9: Extended reception
• Contention type communication in packet transmission mode (including the
headerless stream mode) may cause repetitive retransmission when two modems
are in transmission state in identical timing. This results in the decrease of response
rate or the transmission failure.
• This extend reception function solves such problems as above. The data packet
received during carrier sensing are received first by interrupting the on-going
transmission operation.
Bit 2: Receiving frequency change
0 Regularly change frequency within a group while waiting (default value)
1 Fix the frequency to wait while data can be regularly received.
Table 5–10: Receiving frequency change
• Set the changing method of receiving frequency in packet transmission mode. Sets
roaming function with combining bit 1.
Bit 1: Beacon transmission
0 No transmission until transmission command is requested (default)
1 Enable regular beacon transmission.
Table 5–11: Beacon Transmission
• Enable or disenable beacon transmission in packet transmission mode.
• Set roaming function with combining bit 2.
Bit 0: Reserved
• The FDL01TU does not use this register. Keep the default value as it is.
