AC4486 Specifications
4.6.6 Sleep Walk Power-Down Command
After the Host issues the power-down command to the transceiver, the transceiver will de-assert the
In_Range line after entering power-down. A Client transceiver in power-down will remain in sync with a
Server for a minimum of 2 minutes. To maintain synchronization with the Server, this Client transceiver
should re-sync to the Server at least once every 2 minutes. This re-sync is accomplished by issuing
the Power-Down Wake-Up Command and waiting for the In Range line to go active. Once this occurs,
the Client transceiver is in sync with the Server and can be put back into power-down. This command
is only valid for Client transceivers.

4.6.7 Sleep Walk Power-Down Wake-Up Command
The Power-Down Wake-Up Command is issued by the Host to bring the transceiver out of power-
down mode.
Host Command:
Transceiver Response:
4.6.8 Broadcast Mode
The Host issues this command to change the transceiver operation between Addressed Mode and
Broadcast Mode. If addressed mode is selected the transceiver will send all packets to the transceiver
designated by the Destination Address programmed in the transceiver. If Broadcast mode is selected,
the transceiver will send its packets to all transceivers on that network.
