Change Server / Client
The OEM Host issues this command to change the transceiver mode from Server to Client and vice versa.
Command:
0xCC 0x03 Data1
Bytes Returned: 3
Response:
0xCC Firmware Version Data1
Parameters:
Data1 = 0x00 for Server
0x03 for Client
Sleep Walk Power-Down
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
synchronization 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.

Broadcast Packets
The OEM Host issues this command to change the transceiver operation between Addressed Packets and
Broadcast Packets. If 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.
Command:
0xCC 0x08 Data1
Bytes Returned: 2
Response:
0xCC Data1
Parameters:
Data1 = 0x00 for Addressed
0x01 for Broadcast
