Nortek WEB At our website, www.nortek-as.com, you will find technical support, user manuals, and the latest software and firmware. General information, technical notes and user experience can also be found here. -
Page 5: System Overview
The blue LED will start flashing when power is applied, the flashing means that the DVL is in measurement mode. There are three settings for the LED: ON allows the LED to indicate operation and modes; OFF disables the LED completely. ON24H enables the LED for 24 hours after the instrument starts pinging. © 2017 Nortek AS... -

Do not hesitate to contact us if you find any part of the delivery missing. Connecting the DVL to PC The Nortek DVL offers both serial communications and Ethernet. For a first time use, connect using the Ethernet communication. Ethernet communications The Ethernet communication has been implemented by using a dedicated network processor, and needs to be powered by connecting a power supply to the external power breakout on the cable. -
Page 7: Finding Instrument On Pc
Finding Instrument on PC Nortek Discovery The Nortek Discovery application is a small Windows program that provides a means to locate and configure the network information for instruments (NortekDiscover.exe is available on the flash disk that came with the instrument). Note that it may take minutes the first time connecting. The search application requires an up-to-date version of Java installed on the computer. - Page 8 To find the instrument icon in Microsoft Windows, open the Network view of the computer. Double clicking on the instrument icon brings up the web page interface. Right clicking and selecting Properties gives the IP address and other instrument configuration information. © 2017 Nortek AS...
- Page 9 Public). Select the network type that the instrument is connected to and ensure that Turn on network discovery is selected for that network. If the network is a public network, it is recommended that network discovery be turned off after interaction with the instrument has been completed. © 2017 Nortek AS...

Page 13: Data Output
DVL Integrator's Guide contains a detailed format description for all the different data outputs. The Nortek DVL supports older protocols which have been available (PDxx variants). Otherwise, system integrators may choose to use native Nortek data formats which offer expanded information (independent beam information and quality parameters) and are delivered in efficient data packets. -

Page 17: Before Mission
Online connectors should be lubricated with silicone spray. The Mounting Angle should be set to the non-zero value if the the DVL's X direction is different from the vehicle's or INS's forward direction. See the section on Coordinate System for further clarification. © 2017 Nortek AS... -
Page 18: Practical Elements Of Operation
This means the selection of the correct coordinate system and all necessary conversions are handled by the Nortek DVL. The only matter which requires attention is that the X direction is oriented in the vehicles forward axis. -

Page 20: Dvl Configuration
Check out the Nortek DVL Integrators Guide for examples showing how to setup the instrument to use a specific trigger. When triggered the instrument will perform a complete ping (Tx and Rx) before it goes back to monitoring the trigger. Any triggers asserted during an ongoing ping will be ignored. There are no specific requirements for pulse length. - Page 21 Data: Selects the data format for outputting current profile estimates. The DF3 data format is the most complete and efficient format while the PD0 is complete but contains irrelevant fields and thus consumes more space. NMEA formats are also available. A complete description is found in the DVL Integrator's Guide. © 2017 Nortek AS...

To retrieve this file through the web browser interface, find it under Maintenance. A *.gz file is then downloaded and can be sent directly to Nortek for diagnosis. If it turns out that the instrument will have to be sent back to Nortek for repair, check out http://www. -

Ethernet switch for troubleshooting. Once the IP address is properly configured, it can be used to access the instrument using normal IP communications. Only the discovery protocol uses multicast packets. For more details about the Ethernet communication, refer to the Appendix. © 2017 Nortek AS... - Page 27 There is a way to reboot the network processor even if the WEB page is not working. Do a Discover from MIDAS or Nortek Discovery, click on the instrument to get up the configuration and then right click in the configuration window. This brings up a menu where you can select to Reboot Network Processor.

To determine the IP address assigned, the Discovery protocol is used to query instruments on the local subnet. The discovery protocol is a Nortek proprietary means for retrieving information from an AD2CP without requiring any knowledge of the IP address assigned. - Page 32 Click the highlighted instrument in the Instrument Search dialog to get the option of enabling DHCP or set a static IP address or IP address for a local interface (see section Finding Instrument on PC for description of parameters), or check out the MIDAS software manual. © 2017 Nortek AS...
