Select option (0 for previous
menu):
Users should select the option for their application based on the descriptions below. Note, however, that
the "Start up Normal" selection will be best for most applications.
1- ( ) Start up Normal. This selection is the factory default and should be used for most
operations of the sonde. When power is applied or a "reset" command is issued, the sonde
firmware will return the "#" prompt. The user should then type "menu" to access the sonde
firmware functionality
2- ( ) Start up Menu. When this item is enabled, the sonde will go directly to menu mode when
power is applied to the sonde. If the command line mode is not useful for your applications, then
enabling this item will negate the need to type "Menu" and Enter at the # prompt to access the
Main sonde menu. Activation of this item is NOT recommended except for special applications.
3-( ) Start up Run. When this item is enabled the sonde will start sampling and output data as
soon as power is applied to the sonde. If you are using your sonde for Unattended sampling, do
not activate this mode. Activation of this item is NOT recommended except for special
applications.
4-( ) Start up Menu Run. When this item is enabled, the sonde will first enter the menu mode
and then the run mode where it will start sampling. If you are using your sonde for Unattended
sampling, do not activate this mode. Activation of this item is NOT recommended except for
special applications.
5-( ) Start up NMEA. When this item is active, the sonde will start sampling and output data in a
format which is compatible with devices which utilize the NMEA protocol. See Appendix N -
NMEA Applications for additional details. Activation of this item is NOT recommended except
for special applications.
3-( )Comma radix. When this item is enabled, the sonde will replace decimal points with commas when
printing numbers. NOTE: Regardless of this setting, SDI-12 'D' commands will still respond using a
decimal point.
4-(*)Auto sleep RS232. Activation of this feature enables a power savings system when communicating
with the sonde in RS-232 mode. When enabled, power is only applied to the sensors during sampling or
calibration. The most important aspect of this feature is its effect on the dissolved oxygen protocol as
described in Section 2.9.2. For this reason, this feature should be activated for long term monitoring
studies in the RS-232 communication mode and deactivated for sampling studies where the user is present
and the sonde runs continuously. Even with Autosleep inactive, the sonde will "sleep" after one minute
with no communications.
5-(*)Auto sleep SDI12. Activation of this feature enables the power savings system when communicating
with the sonde in SDI-12 mode. This is basically the same as item 5 above except that it is used in
communication via the SDI-12 interface. Also, the sonde will "sleep" in about 100 milliseconds in the
absence of communication, rather that waiting one minute in the Auto sleep RS-232 mode.
