The following table gives the text commands. Each command and response ends with a carriage return <CR>
which is hexadecimal 0x0D. Each command and response is case sensitive.
Text Command Text Response Description
wake
OK
When in the SLEEP state, transitions to the ON state.
Because this wakes up the Tesira host card from SLEEP, the
Tesira host card will respond with the text response once it
is powered up and ready to receive new commands. This
does nothing if already in the ON or STANDBY states but
still provides a response.
status
See power states below Returns the status of the power state of the Tesira host card.
set power <value>
OK
Transitions to the power state specied by the value. This
text command to turn on the amplier and then use this
command to change the power state.
version
<text>
The version of the power microcontroller rmware, not Tesira
rmware. This is for internal use as it does not provide any
useful information to the user.
