CN - Save NVRAM to Recorder

Purpose: Saves the contents of NVRAM to the recorder at the end of a deployment.
Format CNn
n = 0 (On), 1 (Off)
Range
Default CN1
Recommended Setting. The default setting for this command is recommended for most applications.
Description The CN command allows the contents of the NVRAM (approx. 8k bytes) to be written to
the recorder as part of the deployment record. This can be useful for troubleshooting pur-
poses.
CP – Polled Mode
Purpose: Allows the H-ADCP to be polled for data.
Format CPn
n = 0 (Off), 1 (On)
Range
Default CP0
Recommended Setting. The default setting for this command is recommended for most applications.
Description The CP command allows an H-ADCP to be polled for data. Setting the CP command to
CP1 places the H-ADCP into a mode where it doesn't sleep. Instead, the H-ADCP stays
awake between pings listening for certain commands (and drawing more power). Polled
mode is only recommended for deployments where shore power can be provided. The
commands the H-ADCP responds to while in polled mode are shown in Table 18.
The polled mode requires sufficient time between pings to listen for the polling com-
mands. Setting the TP command to 1 second normally gives the H-ADCP enough time for
polling (see
In the polled mode (CP1), enough time must be allowed in the ensemble cycle (TE or TP
commands) to allow the system to check for serial input. If both TE and TP are set to zero for
the maximum ping rate, the system will not recognize any keyboard input with the exception of
a <break>.
The output of the polled mode is on demand. If the H-ADCP is in the middle of an en-
semble when the command arrives, it will send out the last completed ensemble, even as
it continues to collect data for the current ensemble. Note that the polled mode does not
output data until at least one ensemble has been completed.
