Configuring the PKLR2400
Preliminary

7.2.1
Transmit Data Link Attempts
EEPROM Address: 2FH
Size: 1 byte
Default: 10H
Range: 01-FF
This parameter specifies the maximum number of attempts over the RF interface. Serial Interface
mode 03 will respond with a Send Data Failure when maximum Data Link attempts is achieved. All other
modes will not receive an acknowledge.
Note: Transmit Data Link Attempts must be set to 01 when operating in the Broadcast Mode of the
Address Transparent Control.
7.2.2
Receive mode
EEPROM Address: 31H
Size: 1 byte
Default: 01
Range: 01-03
This parameter applies only to API Serial Interface Mode 03. The default, 01, specifies
Unicast/Broadcast. Unicast will receive all packets that match the receiving unit IEEE assigned address.
Broadcast is achieved by placing FF in all six bytes of the IEEE assigned destination address sent from
sender. In Broadcast mode, the receiver will accept all data with a destination address that has FF in all six
bytes.
It is important to note that there is no RF acknowledge on Broadcast packets
. Mode 01 will
accept Unicast and Broadcast data packets and discard all others. In Unicast only mode, 02, The receiving
radio will receive only Unicast packets and discard all others. In Promiscuous mode, 03, the receiving radio
will accept all packets with the same System ID.
Note: The Receive Mode must be set to 03 in all Transparent Serial Interface Modes including 01, 02
and 04 at EEPROM location 4AH.
7.2.3
In-Range, Out-of-Range Refresh
EEPROM Address: 32H
Size: 1 byte
Default: 14H
Range: 01-FF
This parameter is used only when the radio is operating in API Serial Interface Mode 03. The In-
Range, Out-of-Range Refresh parameter allows the user to select the interval between which the client radio
searches for Server beacon that includes the Server IEEE source address. This parameter is very useful
when operating in a fringe condition to minimize the In-Range and Out-of-Range commands that may flood
the host. AeroComm has established a default value of 5 seconds through extensive testing.
