System Overview
The Workhorse II ADCP transducer assembly contains the end-cap, housing, transducer ceramics, and
electronics. The standard acoustic frequencies are 1200, 600, and 300 kHz. See the Outline Installation
Drawings for dimensions and weights.
Picture Description
The cable connects the Workhorse II ADCP to the computer and external
power supply. When the cable is not connected, use the dummy plug to
protect the connector.
The end-cap holds the Impulse MCIL-8-FS connector.
When assembling the unit, match the Beam 3 mark on the end-cap with
beam 3 number on the transducer.
The Vent plug provides a way for internal pressure to escape once the
plug is backed out and is no longer sealed yet the threads remain
engaged. This is important in cases where there’s a concern about the
plug becoming a projectile should there be internal pressure inside the
housing.
The Beam-3 mark shows the location of Beam-3 (Forward).
The Thermistor measures the water temperature.
The pressure sensor (standard 20 Bar, 200m) measures water pressure
(depth).
The urethane faces cover the transducer ceramics. Never set the trans-
ducer on a hard surface. The urethane faces may be damaged.
The standard Workhorse II white plastic housing allows deployment
depths to 200 meters.
The Workhorse II electronics and transducer ceramics are mounted to
the transducer head. The numbers embossed on the edge of the trans-
ducer indicate the beam number. When assembling the unit, match the
transducer beam number 3 with the Beam 3 mark on the end-cap.
The Sentinel ADCP includes a longer housing to hold a battery. The inter-
nal alkaline battery pack has 450 watt-hours (Wh) of usable energy at 0
C. Lithium batteries have a capacity of approximately 1650 Wh.
Workhorse II Sentinel ADCPs come standard with one Delkin C600 series
CompactFlash memory card with the maximum memory capacity not to
exceed 4GB per deployment.

Workhorse II Models and Options
The following section explains the different models and options available for Workhorse II ADCPs.
Workhorse II Monitor
The Workhorse II Monitor is designed to measure real-time current profiles from temporary or perma-
nent mounting in the ocean, near-shore, harbors, and lakes. The Monitor ADCP system consists of an
ADCP, pigtail cable, CompactFlash (CF) memory card, and software. The Monitor system requires the ad-
dition of a Windows® compatible computer to collect data.
Figure 1. Workhorse II Monitor ADCP
Workhorse II Sentinel
The Workhorse II Sentinel is designed for several-month autonomous current profile deployment from
temporary or permanent mounting in the ocean, near-shore, harbors, and lakes. The Sentinel ADCP sys-
tem consists of an ADCP, cables, battery pack, CompactFlash (CF) memory card, and software. The bat-
tery capacity can be increased with upgrades for longer deployments. The Sentinel can also be used for
direct-reading current profile operation. The Sentinel system requires the addition of a Windows® com-
patible computer to configure the ADCP and replay collected data.

Workhorse II Mariner
The Workhorse II Mariner is designed to measure real-time current profiles from temporary or perma-
nent mounting in a vessel. The Mariner ADCP system consists of a Monitor ADCP with Bottom Track
mode, cables, Deck Box, Mounting Plate, CompactFlash (CF) memory card, and software.
The Deck Box converts AC power input or 12 VDC input into 48 VDC output for the Mariner input power.
It can convert the computer serial interface from RS232 to RS422. The Mariner system requires the addi-
tion of a Windows® compatible computer to collect data.

Workhorse II Options
•Conversion Cable – Converts from the new 8-pin circular Impulse MCIL-8-FS connector to the flat
7-pin Impulse LPMIL-7-FS connector. Use this cable to connect the Workhorse II to an existing
cable installation.
•Bottom Track – You can use your Workhorse II ADCP from moving boats and ships with the Bot-
tom Track upgrade. Once the Bottom Track upgrade is added, a Workhorse II ADCP can measure
both water depth and boat velocity over the ground.
•Shallow Water Bottom Track Mode 7 – You can use your Workhorse II 1200 kHz ADCP in water as
shallow as 30cm. This firmware feature is included with all 1200 kHz Workhorse II ADCPs (re-
quires Bottom Track option enabled).
•High-Resolution Water Profiling Modes – This firmware feature allows you to collect water profiles
using Water Modes 1 (default) and 11. This firmware feature is included with all Workhorse II
ADCPs.
•High Ping Rate Water Mode – This firmware feature allows you to collect water profiles using Wa-
ter Mode 12. This firmware feature is included with all Workhorse II ADCPs.
Water Modes 11 and 12 were designed for 600 and 1200 kHz ADCPs. Using these modes on
300 kHz ADCPs is not recommended.
•Waves – This upgrade allows you to use the ADCP as a wave gauge.
•Lowered ADCP – This upgrade enables the Water Mode 15 Lowered ADCP mode. WM15 is also
used for Surface Tracking to track boundary layers such as the air/sea surface or the bottom of an
ice layer.
For more information on LADCP deployments and WM15, see the LADCP User’s Guide.

•Lithium Battery Pack – The optional Workhorse II Lithium Battery Packs can be used interchange-
ably in Workhorse II Sentinels and the external battery case. This battery pack is assembled using
lithium battery cells that provide 34 VDC with a capacity of approximately 1650 Wh. The battery
includes a safety circuit that protects the battery and users against short circuits and provides us-
ers the ability to test the pack. The circuit also turns the battery off at its end of life before the bat-
tery fully discharges. This happens when about 97% of the battery’s capacity is depleted.
Mariner Options
•Mounting Plate – A bronze plate that helps mount the transducer head to a vessel. See the Outline
Installation Drawings for dimensions.

Mariner Deck Box Overview
The deck Box contains all interfaces to/from the ADCP, computer/terminal, and power.
Power Switch – The power switch is a combination switch/circuit breaker. The Power Status LED next to
the circuit breaker lights when power is applied to the Deck Box.
Reset Button – Pushing the Reset button sends a break to the ADCP.
Data In/Out LEDs – Channel 1 In indicates data transmission from the computer to the ADCP. Channel 1 Out
indicates data transmission from the ADCP to the computer.
Figure 5. Deck Box (Front View)
ADCP (J17) – Connects the ADCP to the deck box.
Channel 1 RS 422 (J19) – Connects the computer’s RS-422 port to the deck box. Use this only if your com-
puter has a RS422 serial port. If your computer has a RS-232 serial port (standard), use J20.
Channel 1 RS 232 (J20) – Connects the computer RS-232 port to the deck box.
Serial RS 232 (J28) – Supplies serial, ASCII navigation data to the computer via our VmDas program. See
the VmDas help file for requirements. This is an option for some ADCP applications. When working in
areas where bottom-track detection is not possible, you need this equipment to remove ADCP (Ship) mo-
tion from the data. The output from the J28 deck box connector is a serial data string of heading, pitch,
and roll. The format of this string is: $PRDID,±ppp.pp,±rrr.rr,hhh.hh (where pis pitch, ris roll, and his
heading; all scaled in decimal degrees).
AC Power Input – The deck box accepts input voltages of 98-264 VAC, 50-60Hz (J27). This input voltage
will be converted to 48 VDC. This is the voltage supplied to the ADCP.
DC 12-Volt Input – Use a 12 VDC car battery (J26) when AC power is not available. The deck box converts
the voltage to 48 VDC. This is the voltage supplied to the ADCP. Use the largest rated amp-hour battery as
possible. A car battery can power a 1200 kHz ADCP for approximately one to two days.
DC 20 to 50 Volt Input – If you are using an external DC power supply connected to the deck box on J25 (20
to 50 VDC, 3.0 A), the voltage from the external power supply is sent directly to the ADCP. This is useful if
you want to increase (higher voltage level) or decrease (lower voltage level) the range of the ADCP. The
current requirement for the power supply is listed as a reference. Using a lesser-rated power supply can
cause the voltage level to drop. The ADCP will draw only the current it needs.

Mariner Triggering Function
In some applications, it is advantageous to have the ability to trigger the transmit cycle of the WorkHorse
Mariner ADCP. Triggering the WorkHorse Mariner ADCP allows you to synchronize the time when it
transmits with other devices to avoid interference between the acoustic instruments.
The standard WorkHorse Mariner Deckbox is designed to work with a WorkHorse Mariner ADCP down
long cables using RS-422 communications. If triggering is desired, then the WorkHorse Mariner Deckbox
must be modified from its standard RS-422 communications link to the Mariner ADCP to a RS-232 com-
munications link.
This modification must be done (or ordered for new systems) at Teledyne RD Instruments
factory and requires the return of the WorkHorse Mariner Deckbox and the WorkHorse
Mariner ADCP.
Please contact your local sales representative if you are interested in modifying your system
for this feature.
All communications and other functions described in the WorkHorse Operation Manual and
Mariner Deployment Guide are correct and apply to the Mariner system.
Using the Modified Deckbox with Trigger
The following procedure assumes you have a modified WorkHorse Mariner Deckbox, and the Mariner
ADCP is set to RS-232 communications. The front of your Mariner Deckbox will be clearly marked indi-
cating that it has Trigger.
Communication Setup
The standard communications setup to the WorkHorse Mariner Deckbox with Trigger remains the same
as with a standard WorkHorse Mariner Deckbox. The only difference is that the WorkHorse Mariner
Deckbox with Trigger has been permanently changed to only pass-through RS-232 communications down
to the ADCP. As a result of this modification, the WorkHorse Mariner ADCP must be set to RS-232 com-
munications. This setting is controlled via a switch inside the ADCP and will have been set by TRDI dur-
ing the modification of your Deckbox if ordered for a new system.
See Changing Communications Setting for more information.
Communications to the WorkHorse Mariner ADCP is through the RS-232 25-pin connector J20 on the
back of the Deckbox. Connect the computer to this connector to establish communications to the Mariner
ADCP.
For reliable communications, the RS-232 cable to Deckbox must be less than 25-meters
length and the J17 cable to the Mariner must be no longer than 25-meters.
Baud Rate Setup Considerations
The default baud rate of the WorkHorse Mariner is 9600. The maximum baud rate possible when using
the WorkHorse Mariner Deckbox with Trigger is 38400. Triggering only works with a baud-rate less than
38400.

Trigger Signals, Breaks, and Commands
The Mariner ADCP Deckbox can only be set up in slave mode (receiving trigger signals from other instru-
ments). The setup is controlled through the Ping Synchronization Commands (SA, SM, ST, and SW). The
default setup for the Workhorse Mariner is for triggering to be disabled (SM0). The SB command must be
set to SB0 to use the Master/Slave setup.
To avoid a trigger-signal being handled as a hardware-break, the SB0 command needs to be set.
To set the SB command to SB0:
1. Send SB0.
2. Immediately following the SB0 command, send a Break.
3. The SB0 command is now in effect and the ADCP will ignore potential <Breaks> on the Channel B
RS-422 lines.
Once the SB0 command is set, it will not be reset by a CR1 command (SB1 is the default
setting).
4. To enable the triggering in the slave mode, add the following commands to the command file used
for the Workhorse Mariner.
SM2
ST0
WP1
TE00:00:00.00
TP000000
Injecting a Trigger Signal
The access to the trigger is via the DB9 connector labeled J21 RS485 on the back of the Deckbox. Pin 6 is
(+) and pin 5 is (GND). The input trigger pulse must be a TTL pulse between 15mSec to 38mSec.
The WorkHorse Mariner only allows a Trigger In signal.
Verify Triggering on The Bench
Before installing the system in the field, verify it on the bench.
1. Connect the Workhorse Mariner to the Mariner Deckbox.
2. Apply power to the Mariner Deckbox.
3. Connect a serial cable from the Deckbox to a PC and open TRDI Toolz.
4. Use a frequency generator to generate a TTL pulse width of 20mSec every second.
5. In TRDI Toolz send following commands:
CR1
WP1
TE00:00:00.00
TP000000
SM2
ST0
CK
CS
The Mariner should now ping every second.
