OceanWorks International 120 – 6741 Cariboo Road Burnaby, BC V3N 4A3 Canada www.oceanworks.com 1. Introduction 1.1. Purpose of Document The purpose of the document is to provide the user with a reference to the nature of the North-East Pacific Time-series Undersea Networked Experiments (NEPTUNE) Junction Box (JB) subsea hardware and software; the deployment and operational use thereof. 1.2. Reference Documents The documents in Table 1.2.
OceanWorks International 120 – 6741 Cariboo Road Burnaby, BC V3N 4A3 Canada www.oceanworks.com 2. Principles of Operation 2.1. General Operation The JB receives 400VDC from a Medium Voltage Converter (MVC) and distributes low voltage (LV) to six to ten instrument ports at 12VDC, 15VDC, 24VDC, 48VDC and high voltage (HV) to up to three ports at 400VDC as defined in the NEPTUNE Junction Box System Design Document (0848-RPT001).
OceanWorks International 120 – 6741 Cariboo Road Burnaby, BC V3N 4A3 Canada www.oceanworks.com 3. Deployment Procedure 3.1. Mechanical and Electrical Interfaces The junction box end plate has 10 SeaCon connectors, numbered J1 through J10. The steps below outline the installation of cables on the JB SeaCon connectors: - - Check that the JB output ports are disabled. Check that the connectors are clean and free of dust or debris. Install o-ring in the face of the SeaCon connector.
OceanWorks International 120 – 6741 Cariboo Road Burnaby, BC V3N 4A3 Canada www.oceanworks.com Do not apply power to the JB unless it is electrically bonded to the power supply chassis. This ensures that there is no potential between the JB chassis and earth ground. This bonding protects personnel who are either floating with respect to earth or bonded to earth via ESD measures. This bonding can be achieved by connecting the JB to earth ground with a #8AWG or larger wire.
OceanWorks International 120 – 6741 Cariboo Road Burnaby, BC V3N 4A3 Canada www.oceanworks.com After the initial 60 second lockout period has passed, control of the JB breakers via TELNET is possible. 5.2. Operational Calibration Procedures Refer to the NEPTUNE Calibration File Format document for a detailed description of how to create a JB calibration file. 5.3. Methods of Commanding and Collecting Data from the System The subsea software is controlled via TELNET.

Flashing Junction Box Firmware The following section details the steps required to download the NEPTUNE subsea controller firmware. Tools required: - Rabbit Field Utility (RFU) version 2.5 (Z-World) When the RFU is run, the main screen as seen in Figure 7.3.1 is presented. Figure 7.3.1.
OceanWorks International 120 – 6741 Cariboo Road Burnaby, BC V3N 4A3 Canada www.oceanworks.com Figure 7.3.2. RFU “Communications Options” Screen Ensure that the TCP/IP option “Use TCP/IP Connection” radio button is selected. If the Network Address displayed is correct, click the “OK” button to proceed. Otherwise, the RFU needs to find programmer units that it can communicate with. This is accomplished by clicking the “Discover” button. The “Discovery” screen given in Figure 7.3.3 is then displayed.
OceanWorks International 120 – 6741 Cariboo Road Burnaby, BC V3N 4A3 Canada www.oceanworks.com Figure 7.3.4. RFU “Communications Options” Screen with Programmer Information If the programmer’s IP address displayed in the “Network Address” field is correct, click the “OK” button. Now select “File” on the menu bar in the main screen. This will bring up the “Choose Flash Image” screen (see Figure 7.3.5), where you select the binary image to download to the JB. Figure 7.3.5.
OceanWorks International 120 – 6741 Cariboo Road Burnaby, BC V3N 4A3 Canada www.oceanworks.com Figure 7.3.6. RFU “Browse for Image” Screen Once the correct image has been located, click the file name to select it. The “Passphrase” screen (see Figure 7.3.7) is then presented. Figure 7.3.7. RFU “Passphrase” Screen There is no passphrase imposed on the system, so click the “OK” button to start loading the image. This will take approximately 70 seconds to accomplish. 7.4.
OceanWorks International 120 – 6741 Cariboo Road Burnaby, BC V3N 4A3 Canada www.oceanworks.com It is strongly recommended that for the final “production” load of the software the code be compiled to the target board (compiler Project Options) and then loaded via the RFU. The target board is: - 44MHz BL2600, 512K Flash, 256K+512K SRAM Rabbit 3000 Revision: IL1T/IZ1T The above procedure ensures that the binary (.
