1.1.     Introduction

The Inertial Labs™ MRU family products (MRU-B, MRU-E, and MRU-PD) are compatible with HYPACK software for hydrographic surveys. HYPACK is Windows-based software for Hydrographic and Dredging Industries. Using the Inertial Labs™ MRU along with the HYPACK hydrographic survey software allows real time data collection and processing for imaging, terrain modeling, and statistical reporting.

For more details about HYPACK software, please visit the website www.hypack.com.

In order to connect MRU to HYPACK it is necessary to do the following:

      To determine a serial port number to which COM1 of the MRU is connected;

      To set the MRU with TSS1 output data format into “Autostart” mode; To set the “Hardware setup” parameters in HYPACK software.

This document provides short description of performing these procedures.

 

1.2.     Preparation

1.2.1.           Serial port determination

Before connecting the MRU to the HYPACK software, it is required to determine Serial Port number to which main COM port of the MRU is connected. This section provides short instruction on how to determine the serial port number (for more detailed explanation, please see “MRU GUI User’s Manual” Section 2, “Installation of drivers and configuration of PC parameters”).


Using the cable provided by Inertial Labs, connect the MRU to a PC and start supplying electricity. The MRU LED indicator should light up in yellow, and then change to red. Now the device is ready for operation.

Open “Device Manager” window on your computer (Fig. 1.1). All connected COM and USB ports are listed under the “Ports (COM & LPT)”. COM ports are marked as “Communications Port (COM1)”, where number “N” is a port number assigned by OS.

If you connect the MRU via COM-to-USB converter, then a port is marked as “USB serial port (COMN)”, where “N” is a port number assigned by OS.

Please remember the number of a serial port for further connection to the HYPACK software.

1.2.2.           Auto start mode and TSS1 output format

The HYPACK software requires receiving data from the MRU in standard TSS1 output format. Before connecting the MRU to the HYPACK software, it is necessary to set the MRU into auto start mode and output data format to TSS1. 

In the auto start mode, the MRU starts operating automatically after power turns on, with continuous output data in desired data format without any commands from a host computer (please see Section 10.5 “MRU automatic start” of the MRU GUI User Manual for more details).

All available output data formats are listed in “Autostart” drop-down list on “IMU” tab of “Device options” menu as shown of the Fig. 1.2. Please choose TSS1 output data format for the MRU autostart for further connection to HYPACK software.

Also, please specify baud rate of main port of the MRU in “COM Port bps” drop-down list and set required frequency of output data in “Data rate (Hz)” field. Please note that it is critical to ensure that chosen baud rate is capable of handling data throughput with desirable data rate. Table 1.1 contains data package length for TSS1 data format and also maximum measurement rate for each possible baud rate.

2.3.     The procedure of connecting the MRU to QINSy

In order to connect the MRU to QINSy software, it is necessary to perform Hardware Setup. This section describes key steps on how to make MRU and QINSy software work together.

Perform these three procedures in order to launch and get QINSy software ready to connect to MRU:

Procedure 1. Creating a new empty template database

QINSy pulls and saves data like configuration and settings of vessel configuration, geodetic parameters, I/O parameters etc. in a relational database.

Procedure 2. Defining parameters in the geodetic wizard

The geodetic parameters wizard allows a user to define all parameters such as the survey datum, the projection type and projection parameters. 

Procedure 3. Defining an object

An object on which equipment, or measuring systems are installed must be defined in QINSy Survey software. An object can be a survey vessel, ROV, SSS fish, drilling rig or a barge.


Once procedures mentioned above are done, the next and the final step is defining a system. System definition procedure is specific per particular equipment. In the next section, it is assumed that Qinsy is being connected to Inertial Labs™ MRU.


For more information and detailed description, Inertial Labs recommends referring to the official QINSy instructions on QPS website: https://confluence.qps.nl/qinsy/en/2-qinsydatabase-setup-35587354.html.

MRU definition

Having defined geodetic parameters and an object, the next steps are to define the MRU or other systems that are going to be used during the survey.

Step 1 Launch the QINSy software (see Fig. 2.3). 

Figure 2.3

Step 2 Start the Setup module from the Console by double clicking on the "Setup" icon in the upper left half of the window. It is assumed that there must “New Database” (see Fig. 2.4) appear in the list, according to steps performed in the previous section, Procedure 1 “Creating a new empty template database”.
