Transparent Mode Operation
Addressed communication in a Transparent Mode is achieved by programming the Transmit Mode
byte, located at EEPROM address 4Bh, to a value of 00h. In addition, the 6-byte IEEE destination
address must be programmed in the respective transceivers starting at EEPROM address 50h (i.e. the
Server IEEE address must be programmed in the Client and the Client IEEE address must be
programmed in the Server). Auto Destination could also be enabled in the Client transceiver as
described in Section 4.6.1.2, Auto Destination

In this configuration, a packet is sent to the destination transceiver until a positive acknowledgement is
received or until all Transmit Attempts have completed. The number of Transmit Attempts is specified
at EEPROM address 2Fh and can be programmed with values ranging from 01h to FFh. If a packet is
not received successfully after all attempts have been made, the packet transmission will be aborted.
The RF acknowledgements in all Transparent Modes are not sent to the Hosts; therefore, the Host is
responsible for detecting a non-deliverable packet, if necessary. Addressed Mode is recommended
for all point-to-point (one Server and on Client) applications because a transceiver only sends the
packet as many times as necessary. For example, if a transceiver receives a positive
acknowledgement before all attempts are made, it will ignore the remaining attempts and start sending
the next packet.

The AC5124 also supports an addressed mode of communication called Auto Destination. Auto
Destination is only for Clients operating in one of the Transparent Modes. To configure a Client for
Auto Destination, set bit 7 of EEPROM address 4Fh to a value of 1. With Auto Destination enabled, a
Client has the ability to detect any Server with the same Channel and System ID. Hence, a Client’s
Destination IEEE MAC Address, located at EEPROM address 50h, is not required to be programmed
with the Server’s IEEE address.

Auto Destination allows a Client to dynamically route all communications to the Server that is in range,
making it useful for mobile or roaming applications where a Client will be interfacing with different
Servers from time to time. It is important to note that multiple Servers with the same Channel and
System ID must not be located in range of one another. Doing so will cause inoperability of the
system.
