Aquaread BlackBox™ Instruction Manual
10401-00618 Rev P
When the white core is subsequently taken above 6V, the BlackBox will wake-up and re-
enter normal running mode but
the data outputs will not be stable and valid for 40
seconds
.
If an AP-7000 is connected, the data outputs will not be stable and valid until
60 seconds
after wake-up.
2.5. Sleep Mode When Configured for SDI-12 Output
When configured for SDI-12 output, sleep mode can be configured to work automatically. If
the white core is tied permanently to ground, the BlackBox will stay in sleep mode unless
woken up by a ‘measurement request’ on the SDI-12 line. As soon as the data is ready to
be sent (usually after 40 seconds), the BlackBox will issue a ‘service request’ to the
controller. Once the controller has read the data, the BlackBox will automatically re-enter
sleep mode.
If the BlackBox is running software revision 2.05 or below and an AP-7000 is connected, a
self clean command will be sent to the Probe each time it is woken up. This will add a
further 20 seconds to the time taken for the readings to be ready.
If the BlackBox is running software revision 3.00 and above and an AP-7000 is connected,
a self clean command is not sent on each wake-up. Software revision 3.00 and above
sends a self clean command every six hours, regardless of the mode selected. For this
reason, it is very important that power is left applied to the BlackBox at all times.
If an AP-7000 is connected, see section
8.4.23 Important note concerning AP-7000 self
2.1 Important Information Regarding the Power Supply.
