The OEM Host issues this command to change the sync channel byte
and enable sync to channel.
Note: Valid only for Server transceivers.
Sl ee p Wal k P o wer - Dow n
After the Host issues this command, the transceiver will de-assert its
In_Range line after entering power down. A Client in power down will
remain in sync with a Server for a minimum of 2 minutes. To maintain
syncronization with the Server, the Client should re-sync at least once
every 2 minutes. This is done by sending the Power Down wake up
command and waiting for the In_Range line to go active. Once this
occurs, the Client is in sync with the server and can be put back into
power-down mode.
Note: This command is valid only for Client transceivers.
S l ee p W al k P o w er - D ow n W a k e U p
The OEM Host issues this command to bring the transceiver out of
Power Down mode.
Note: This command is valid only for Client transceivers.
B ro ad c a st Pa ck e t s
The OEM Host issues this command to change the transceiver
operation between Addressed Packets and Broadcast Packets.
Addressed Packets are selected, the transceiver will send all packets to
the transceiver designated by the Destination Address programmed in
the transceiver. If Broadcast Packets are selected, the transceiver will
send its packets to all transceivers on that network. Setting bit-7 of API
Control to 1 can also enable Broadcast Packets.
W r i t e D e st i n at i o n Ad d r e s s
The OEM Host issues this command to the transceiver to change the
Destination Address.
Note: Only the three Least Significant Bytes of the MAC Address are
used for packet delivery.
