Configuring the PKLR2400
Preliminary 37
Mode 04 specifies Transparent mode with fixed length packets and no timeout. Packets will be
transmitted over the RF interface when the number of data bytes received over the interface is equal to the
buffer specified by the user in EEPROM address locations 43H and 44H.
Note: EEPROM parameters can not be programmed once the radios are programmed and reset in
any of the Transparent modes 01, 02 or 04. The radio must be programmed to API mode 03 to access
EEPROM parameters. This can only be accomplished by holding pin 27 low during and after reset.
7.2.7 Destination Address Control
EEPROM Address: 4BH
Size: 1 bytes
Default: 00
Range: 00-01
This parameter sets the destination address for
Transparent Serial Interface modes only
. The
API Serial Interface Mode 03 utilizes the Receive Mode at EEPROM address 31H to specify address
modes. With Destination Address Control set at the default, 00, the radio will determine if the six byte
IEEE address at 50H matches. If the destination address matches, the data packet is forwarded to the OEM
host. Otherwise the data is discarded. This addressed mode guarantees delivery of the data packet over the
radio link by using aknowledgements.
With Destination Address Control set to Broadcast Mode, 01, clients will receive all data packets.
There are no acknowledgements and no data packet retries in this mode.
Client radios can operate in Destination Address Control Mode 00, providing more reliable
delivery of data to the Server radio. At the same time, the Server radio can operate in Destination
Control Mode 01, acting as a broadcasting server without guaranteed delivery. This provides a
unique method of implementing a data network of many-to-one or one-to-many.
7.2.8 Interface Timeout Control
EEPROM Address: 4DH
Size: 1 bytes
Default: 00H
Range: 00, 40, 80 or C0
The Timeout parameter applies only to the Transparent Serial Interface Mode 01 with fixed length
packets and timeout. This parameter specifies the amount of time between bytes that the radio will wait
before transmitting the data packet.
