The OEM Host issues this command to disable Sync to Channel mode.
Note: This command is valid only for Servers.
D ee p S le e p M o d e
The OEM Host issues this command to put the transceiver into Deep
Sleep mode. Once in Deep Sleep mode, the transceiver disables all RF
communications and will not respond to any further commands until
being reset or power-cycled.
Note: This command is valid for both Servers and Clients.

The OEM Host issues this command to read the onboard temperature
sensor. The transceiver reports the temperature in

Pr obe
When the OEM Host issues this command, the transceiver sends out a
query every 500 ms.
randomly choose a query to respond to. After responding to a Probe,
the transceiver will wait at least 10 seconds before responding to
another probe.
Note: This command can only be sent from a server radio.
Transceiver’s Response
Upon hearing the remote transceiver’s probe acknowledge, the
transceiver sends a response to the OEM Host.
