1.17.4 Probe Access Rights
Some OCEAN SEVEN 310 configurations and functions are password protected to avoid unwanted
modifications or running of functions that can led to probe unpredictable behaviours. In each menu and
sub-menu, it is present a hidden command <CNHI>, which allows the operator to modify the probe
access rights. Three different access rights are foreseen by the OCEAN SEVEN 310 management
firmware:
USR User access to perform daily operations and standard probe configuration and management. At
this level, it is not possible to modify certain sensors configuration or probe operating parameters.
Moreover, some probe commands are hidden.
SRV Service access to allow the operator to carry out advanced set-up and advanced diagnostic
functions.
ADM Administrative access to allow full control of the OCEAN SEVEN 310. This access is reserved to
IDRONAUT technicians or to trained operators. Upon request and under IDRONAUT control,
administrative access can be granted to the operator to carry out dedicated functions or
configurations.
The probe access right is indicated on the menu headers with an acronym shown inside {} brackets:
OCEAN SEVEN 310 - ID:0317003 {USR}(1.0_10 05/17)Oct 01 14:19:51.61 2016
At the start up, the probe operates in user “USR” mode. Service or Administrator access must be
configured using the access rights configuration command. Once the <CNHI> command is invoked, the
following message appears on screen:
Set the PROBE Access rights<<
The customer must reply to the password request with a 10-character message. The possible answers
are
“SERVICE310” to grant SERVICE access to the probe functions and configuration.
“****************” to grant ADMINISTRATIVE access to the probe. Administrative password can be
obtained from IDRONAUT only.
It is worthwhile mentioning that the probe always wakes up with “USR” access right. The modification
of the access right remains valid until the probe is switched off or the access right is modified. Typing
an arbitrary password causes the probe access right returning to the USR level.
1.17.5 Data transmission protocol
Whenever the probe runs in “NON-VERBOSE MODE”, interaction with the user is performed by means
of the "DATA TRANSMISSION PROTOCOL". Selection among the data transmission protocols can be
done by means of the configuration parameters.
1.17.6 Data transmission protocol: PTP Point-to-point
The ASCII based protocol is easy to use and allows data transmissions point by point. The protocol
implies bidirectional half-duplex data transmission between the probe and a PC. The probe, which is
always the slave device, does not send any message unless requested by the master PC. Special
characters used by the PTP protocol are:
<CTRL-T> switches the probe immediately from verbose to non-verbose operating mode.
<CTRL-J> special character used to terminate the PTP protocol messages.
<DEL> special character used to clean the probe PTP protocol message input buffer.
