1.0 Introduction
The Model 881A-GS and 881L-GS (hereafter called 881A/L-GS) are advanced gyro-stabilized, high-resolution
scanning sonar systems that have been designed to provide simple, reliable, and accurate representation of
underwater targets. The 881A-GS is a serial device and the 881L-GS is connected via ethernet. Gyro stabilization
means that the sonar is capable of crystal-clear visualization from moving ROVs without the blurring effects of host
vehicle rotation. An advanced, low drift gyro is integrated directly into the sonar head, so the sonar can now
compensate for vehicle motion in real time with accuracy and stability. Gyro stabilization is very useful to ROV
pilots when working in close proximity to targets.
The Sonar is interfaced via Serial (RS-232 or RS-485) or Ethernet depending on the model (881A-GS – serial and
881L-GS – ethernet).
Both units deliver a high level of performance with the 881L-GS ethernet unit able transfer data at a higher rate
which leads to improved range resolution.
The 881A/L-GS sonar comes with a free Windows™ program that is used to interface with the sonar, control
settings, log and play back data.

2.0 Getting Started
The following points describe the set-up procedure:
•Physically mount the sonar. Refer to Section 2.1 for details.
•Ensure 24 VDC @ 1 A minimum power supply is off.
•Configure the network card’s IP address (see Sections 3.4.2 and 3.4.1) or Comm port when using 881L
and 881A respectively.
•Connect the RJ45 connector to the PC’s network port or cable to the PC’s Comm port (881L and 881A
respectively).
•Plug the underwater connector to the sonar.
•Deploy to stable, flat location.
•Power up the 881A/L-GS.
•Wait for gyro calibration to complete. The sonar, upon power up will calibrate the motor, delay for 30
seconds and automatically perform a gyro calibration. No communication to the gyro sub-system is
available at this time.
•Launch the Win881AL_GS.exe program.
•Verify the local latitude and declination setting (see Section 3.5.8) and adjust if necessary.

2.1 Hardware Installation
Figure 2-1 External View
A: Transducer. FRAGILE. This area must not be obstructed. Do not attach any brackets or fastenings to this area.
B: Connector. Ensure locking sleeve is used. Do not bend pins.
C: Oil filling port. Do not remove. Represents moving transducer Zero position.
D: Electronics bottle. Use this area to mount the sonar.
2.2 Software Setup
The latest version of the Win881AL_GS.exe program is available from the Imagenex Technology website
(https://imagenex.com/interior-page/software-download). The installation of the software on the PC is
straightforward. It can be installed in its own directory, and run by double clicking, or you can create a shortcut from
the desktop for it. It is not recommended that the “New Program Wizard” nor any other installation program be used.
If present, a Win881AL.INI file will be read and the settings from the previous time the application was run will be
used.

2.3 Interface
Controls:
Connect to a physical sonar head
Open a File play-back session
Start / Stop recording an 81R data file
Scan in polar mode which means the sonar will do 360° rotations. Direction (CW / CCW) is toggled
by clicking Rev.
Scan in a sector defined by the Sector setting.
Displays a Side Scan type image showing intensity of return.
Pauses Real Time or Playback
Changes the sweep direction. Toggles clockwise / counterclockwise
Refreshes display
Restore default zoom and pan.
Zoom in display.
Zoom out display.
Ruler. Measures distance in metres or feet (depending on Options > Units selection) on the display.
Opens a diagnostics window.
Opens a window with speed keys and other settings (See Appendix A)

Figure 2-3 File Pos and Speed Control
Used during Playback and allows the user to adjust the playback speed and File position (see Figure 2-3 File Pos
and Speed Control above)
Figure 2-4 Sonar Attributes
Used to control various sonar attributes. Only available in Real Time (see Figure 2-4 Sonar Attributes above)
Range: Set the maximum range of target detection. Maximum 200m.
Gain: Set the sonar gain. Max 40 db. Adjust until display optimized.
Sector: Define the scan sector (0° – 360°).
Train: Allows for the rotation of the sector set above around the centre
Speed: Define the scan speed of the sonar. (Slow – Fastest).
Mode: Polar / Sector / Side Scan, as described in Table 2-2 Toolbar Options.
Enable ES: Not used for the 881A/L-GS.
Range: Not used for the 881A/L-GS.
Gain: Not used for the 881A/L-GS.
