ADVField Operation Manual (September 1, 2001)
2.3. ADVField Real-Time Data Collection Setup
The ADVField (with 16-MHz MicroADV, 10-MHz ADV, or 5-MHz ADVOcean probe) uses a
processing module that consists of three printed circuit boards. The processing module can be
enclosed in a splash-proof housing or in an underwater canister. The two mechanical versions use
different cables and connectors (see §4.3), but the basic operation is identical. Please note that
real-time data collection is identical for ADVField systems that include the optional internal re-
corder and battery power for autonomous operation. The internal recorder in real-time systems
can be used during data collection as a backup in case communications are lost.
For real-time data collection, the ADVField typically uses an external power source supplying
12-24 VDC. Any power source supplying 12-24 VDC with sufficient capacity can be used. Dur-
ing continuous operation, the instrument (regardless of acoustic frequency) consumes 3-5 W. The
connectors on the splash-proof housing and the cable from the underwater canister match the
power supply included with the ADV.
The ADVField with splash-proof housing can also be configured with a rechargeable battery for
field data collection; the battery has capacity for about 8 hours of operation. A battery charger is
included with any ADV equipped with the rechargeable battery. See §4.5 for information about
the ADV with rechargeable battery. See §2.4.1 for details on calculating power requirements.
2.3.1. Preparing the ADVField for Real-Time Operation
1. As necessary, review the operational considerations presented in Section 5.
2. Connect the high-frequency cable from the probe to the processing module. Connect the
high-frequency cable to the probe. For the underwater ADVField, connect the power and
communication cable to the underwater canister. See §4.3 for cables and connector details.
3. Connect the serial port of the ADVField to an available serial port on the controlling com-
puter. For the splash-proof ADVField, this is done by directly attaching a ribbon cable from
the processor to the computer serial port. For the underwater ADVField, the power and
communication cable from the underwater processor is terminated with a DB9 connector that
can be connected directly to your computer.
4. If you are using the system directly out of the box, go to Step 5; otherwise, you may need to
edit the ASCII text file
ADVPROBE.DEF
. This file should contain one line that looks similar to
PROBE 0 A001.PRO
. The number
0
indicates the address of the ADV to which you are estab-
lishing communications (only applicable for RS-485 operation).
A001.PRO
is the probe con-
figuration file included on the software diskette. Be sure the name of this file corresponds
with the serial number of the probe connected to the ADV processor, and that the probe con-
figuration file is in the ADV software directory and is for the most-recent calibration.
CAUTION
To collect valid velocity data, you must load the correct probe configuration file. You can
use the ADF.EXE data acquisition software with the configuration file specified in ADV-
PROBE.DEF, or use SonUtils|Terminal|Load Probe Config. Once loaded, the con-
figuration file is stored in memory in the processing module. If you have multiple probes,
be sure to load the correct configuration file before you start data collection.
5. Supply power to the system using the power supply included with the system, or by pressing
the power switch on the splash-proof ADVField with the optional rechargeable battery.
6. Enter your data collection parameters using the software that has been provided (§2.3.2) or by
using the direct command interface via a dumb terminal or terminal emulator (§2.5).
7. Deploy the instrument and start data collection and analysis.
