you would use the <Ctrl+C> command to access the command console. To do
this, press and hold the Ctrl key followed by the C key. This is the same as
sending the hexadecimal equivalent byte “03” to the instrument over the
telemetry interface. This number is also indicated in the table.
Command
Hex
Description
<Ctrl+C>
03
This command interrupts normal operation of
the instrument and invokes the
Command
Console
. See section
E - CONFIGURATION
for more information.
<Ctrl+S>
13
This command stops
free-running
telemetry
output, enabling
polled
telemetry output.
<Enter> or
<SPACE>
0D or 20 If the instrument is running with
polled
telemetry output, either of these commands will
force the instrument to sample its sensors and
return a telemetry frame.
<Ctrl+A>
01
This command stops
polled
telemetry output,
enabling
free-running
telemetry output.
<Ctrl+P>
10
This command powers down the operational
components of the instrument. This may
reduce the instrument’s total power
consumption, as any electronics associated
with sensor operation will be turned off, if
possible. The instrument is otherwise fully
operational, so communication is still possible.
When operational components are powered
down, telemetry output is disabled, regardless
of the telemetry output mode.
<Ctrl+U>
15
This command returns power to the operational
components of the instrument if they were
previously powered down. Telemetry output will
resume based on the current telemetry output
mode.
<Ctrl+R>
12
This command forces the instrument to reset
itself. After a few seconds, the instrument will
reboot and the initialization sequence will begin
again.
With the exception of the <ENTER> and <SPACE> commands, repeatedly
sending a command will have no effect. For example, you cannot power down
operational components more than once.
The free-running and polled telemetry output modes described above are sub-
modes of normal operation. When the instrument is free-running, telemetry
