  • Page 6: Overview

    3.0 Overview The ISD4000 is a pressure measurement device – making use of increasing pressure in water to determine depth. It is important to note that the device is designed to provide depth & temperature measurements in water, and will not provide accurate readings when operated in air.

  • Page 7: Installation

    This will help to minimise the build-up of sediment on the pressure sensor. 4.1.2 Magnetic Disturbers (For Heading Accuracy) Where the heading output is to be used, the ISD4000 should be mounted as far as possible from sources of magnetic interference.

  • Page 8: Alignment With Vehicle (For Pitch/Roll Accuracy)

    4.1.4 Heat Sources (For Temperature Accuracy) In order for the ISD4000 to read the ambient temperature of the water, it should not be installed in close proximity of any heat sources (such as Hydraulic Power Packs).

  • Page 9: Mounting

    ISD4000. The ISD4000 has two flats, on either side of the body – these are to enable the unit to sit tightly against another flat surface if available. These flats also help prevent the unit moving when on the workbench for testing.

  • Page 10: Electrical

    IMPACT SUBSEA INNOVATIVE UNDERWATER PRODUCTS www.impactsubsea.com 4.3 Electrical The ISD4000 is fitted with a SubConn MCBH8M-SS connector as standard. This will mate to a SubConn MCIL8F connector/cable assembly. 4.3.1 Connector Pin Out The standard connector pin out is provided below:...

  • Page 11: Power

    INNOVATIVE UNDERWATER PRODUCTS www.impactsubsea.com 4.3.2 Power The ISD4000 is polarity protected and fused with a 400mA resettable poly fuse. Internal circuitry isolates the supply from the outside environment requiring the serial interface to use the digital 0v reference pin. 4.3.3 Serial Interface The RS232 and RS485 interface has in-line fused protection on the serial lines.

  • Page 12: Rs485 Wiring

    IMPACT SUBSEA INNOVATIVE UNDERWATER PRODUCTS www.impactsubsea.com 4.3.5 RS485 Wiring The RS485 termination resistor is software selectable. The digital 0V must be connected on an RS485 interface, otherwise the voltage potential between one of the A+ or B- lines to ground could reach a damaging level Document No: 0000.1907 | Version No: 1.9 | 19...

  • Page 13: Establishing Communications

    The default serial settings are RS232, 9600, N81 If the ISD4000 is tilted from vertical to upside down 3 times within the first 10 seconds of power up then it will temporarily configure the serial interface to the default and output an ASCII message with the settings.

    RS232 or RS485 at any standard baud rates above 4800. The parity must be none, stop bits 1 and data bits 8. If the ISD4000 communication settings differ from this then perform the comms reset as described in the establishing comms section of this manual.

    Autonomous mode will make a measurement and output the results at a specified time interval. The ISD4000 can be configured to operate in one or both of these modes at the same time. ISD4000's with the AHRS option make use of the same Interrogated and autonomous mechanisms to output heading pitch and roll data over the serial interface.

  • Page 17: Calibration

    ISD4000 calibration block. The calibration block is available from Impact Subsea. Using the Impact Subsea Software, a calibration of both temperature and pressure can be performed on the ISD4000. The software provides a step by step guide to talk the user through the calibration procedure.
  • Page 18 5.4.1 Magnetic Calibration Procedure Step 1: Ensure that the ISD4000 has been physically installed in a location as free from magnetic interference as possible (away from value packs, thrusters etc). Step 2: Check that the ISD4000 is mounted securely to the structure ensuring the unit is not able to move independently from the structure.
  • Page 19 IMPACT SUBSEA INNOVATIVE UNDERWATER PRODUCTS www.impactsubsea.com Step 5: Once connected to the ISD4000, go into the ISD4000 settings: seaView V3.0 seaView V1.9.0 Step 6: For seaView V3.0 onward: Select ‘AHRS Settings’ then click on ‘Calibrate Mag’ For seaView V1.9.0 and earlier: Click on the 'Calibrate' button to open the calibration window: Document No: 0000.1907 | Version No: 1.9 | 19...

  • Page 21 IMPACT SUBSEA INNOVATIVE UNDERWATER PRODUCTS www.impactsubsea.com Step 9: Rotate the ROV through 360 degrees. Step 10: Keep rotating the ROV through 360 degrees and pitch/roll the ROV as much as is possible. On screen you will see the sides of a ball forming from a number of dots. Click on the ball to rotate and see if there are any gaps in data.
