Description
oxE3 = Enable CMD/Data RX Disable
0xFF = Disable CMD/Data RX Disable
Maximum number of times a packet is transmitted when
Addressed packets are selected.
Note: Do not set to 0.
Number of times each packet is transmitted when Broadcast
packets are selected.
Note: Do not set to 0.
Settings are:
bit-7: Aerocomm Use Only
bit-6: Aerocomm Use Only
bit-5: Unicast Only
bit-4: Auto Destination
bit-3: Client Auto Channel
bit-2: RTS Enable
bit-1: Duplex
bit-0: Auto Config
Specifies a byte gap timeout, used in conjunction with RF
Packet Size to determine when a packet coming over the
interface is complete (0.5 ms per increment).
Used to synchronize the hopping of collocated systems to
minimize interference.
Used in conjunction with Interface Timeout; specifies the
maximum size of an RF packet.
Note: Must be set to a minimum of 6 in order to send the
Enter AT command.
CTS will be deasserted (High) when the transmit buffer con-
tains at least this many characters.
Once CTS has been deasserted, CTS will be reasserted
(Low) when the transmit buffer is contains this many or less
characters.
Used to increase/decrease the output power.
Note: The transceivers are shipped at maximum allowable
power.
