Optical fiber conduit fishing
VERY IMPORTANT: When manipulating the optical fiber, be very careful not to bend it too much as permanent damage could occur.
One end of the FOC has a removable metal wire to be used as a fisher attachment for fishing the FOC through plastic conduit. Once the fiber is in place, this attachment can be removed, along with the zip ties.
Also, depending from which end of the conduit the FOC is started, you may also have to remove the strain relief. It is NOT needed at the DVLC end, but IS needed at the DVOR end.
I/O Board and Optical receiver wiring
1- Remove the cover from the DVOR.
2- Using the 3 hookup wires provided in the kit, connect the Optical Receiver (DVOR) to the I/O Interconnect board (MIOBU) such that:
One wire goes from the MIOBU +12V terminal to the DVOR +12V terminal (use the red wire)
One wire goes from the MIOBU AGND terminal to the DVOR GND terminal (use the black wire)
One wire goes from the MIOBU Status Input #8 terminal to the DVOR Kout terminal (use the white wire)
At this time, do not yet reinstall the cover on the Optical receiver.
3- Plug the I/O Interconnect board into the rear of the DV-Micro unit.
Lightning Strike Counter internal battery installation
1- Remove the cover from the Lightning Strike Counter module.
2- Remove the side screw of the internal shielding cover and remove the cover.
3- Insert the CR123A battery into the socket as shown in the figure below.
4- Gently reinstall the internal metal cover of the DVLC-1 module and its retaining screw. Do not overtighten the screw. At this time, do not yet reinstall the main cover on the DVLC-1.
Apply only a very light torque as stripping might occur (screw inserts into plastic part).
5- You can verify that the battery is good and properly installed by pressing on the Test button. If the green LED lights-up, everything is OK.
Optical fiber connection
VERY IMPORTANT
- When manipulating the optical fiber, be very careful not to bend it too much as permanent damage could occur.
- When inserting the fiber ends into optical receptacles, some pushing force may be required, but if you find that it does want to fit, verify polarization and try again. DO NOT OVERPUSH. Also, some pull strength may be required for removal.
Before connecting the optical fiber to any of the two modules, you will need to remove the protective rubber boots. Also, take note of the polarization found on each of the optical fiber connectors.
DVLC Optical Fiber connection
As seen in the image below (left side), on the DVLC-1, insert one end of the optical fiber through the entry hole, then form a gentle “strain relief” loop, and delicately insert the optical fiber tip into the optical receptacle (right image), making sure to match the polarization of the FOC tip with the polarization of the optical receptacle.
Do not yet install the cover on the DVLC-1 as we will later need to access its Test button.
DVOR Optical Fiber connection
1- Before connecting the optical fibre to the DVOR, take note that here too the optical receptacle is polarized.
2- On the DVOR, while still taking care of the optical fiber receptacle polarization, insert the other end of the optical fiber into the optical receptacle.
3- Carefully slide the long strain relief of the FOC over to the DVOR.
4- Reinstall the cover on the DVOR. Make sure to tighten the screws enough because a good electrical contact is required between the cover and the case – however, be careful to not overtighten and strip the threads.
Powering-up the DV-Mini and connecting to it
1- Using the provided 12 VDC power supply, apply power to the DV-Micro.
2- Once the DV-Micro is connected to power, give it 2 minutes to boot up. The unit will be ready once the DC POWER LED is ON solid, and the ACTIVITY LED is blinking at a rate of about 1 pulse per second.
3- Lastly, connect a USB cable between the DV-Micro’s front panel USB port and a USB port on your PC.
4- This completes the hook-up steps. We will now move on to software installation and use.

Connecting to a unit

Setting up the DavLink Workspace
1- First, we need to close any open workspace. Go in DavLink’s top menu and click on File, then Close Workspace. If a Workspace is still present, close it also.
2- Insert the provided Flash drive into a USB port of the PC.
3- Still in DavLink’s top menu, click on File, then click on Open Workspace, browse to the Flash drive location and follow this path: Drive:\DVLC-1 Lightning Strike Counter Files\Workspace file for DavLink\ and select the Workspace for DVLC file.
4- The following workspace will load:
5- If you wish, you can set this workspace to be the default one so it that it opens automatically every time you connect to the Davicom unit. To do so, in DavLink’s menu, click on File, then select “Set Current Workspace As Default”.
6- Now go in DavLink’s top menu and click on Setup, then click on Options.
7- In the Logon window, enter SUPER in the Username box, and enter SSSSSSSS in the Password box.
8- An Options – Properties box will appear, double click on the Quick Commands line and select 2 – Double Click. Click on OK to exit. This setting will allow to manually reset the counter using the double-click action from a mouse.
Loading the configuration file into the DV-Micro
NOTES:
- If you just went through all the previous steps, you are already connected to the DV-Micro. Otherwise, go to Section 10 in order to get connected, then come back here.
- At this step, a configuration file is required. You should already have it, either on the Flash drive that came with this kit, or from a download. If you don’t have this configuration, please contact us.
1- In DavLink’s top menu, click on Unit, then Unit Utility, then Configuration Transfer.
2- The window shown below will open. Click on Browse, and navigate to the Flash drive location and follow this path: Drive:\DVLC-1 Lightning Strike Counter Files\Configuration file for Davicom unit\ and select the DVLC-1 configuration file for Davicom DV-Micro file.
3- Next click on Upload (PC to Unit).
4- The configuration file will be loaded into the unit. Progress messages will be shown during and after the data transfer. Wait to see Success before moving on to next step. Click OK when completed.
5- Now back in the DavLink workspace, after the Config file upload, if the value displayed in the Lightning Strike Hits Count box is not 0, double-click on the RESET button in order to reset it to 0.
Lightning Strike Counter setup test
1- On the Lightning Strike Counter module, a test button is provided (see Figure 34) in order to verify if everything is working properly. Pushing the test button generates an electric impulse which is picked-up by the detector coil, exactly as if a real lightning strike had occurred.
2- When pushing the test button, a battery voltage test is also performed to verify the state of the internal battery. If the battery is ok, the green LED will come on; if the battery is too low, the LED will not light, meaning that the battery (CR123A) will need to be replaced.
3- You are now ready to test the setup. If you push the test button, you should see incrementing values in the Lightning Strike Hits Count box in the DavLink workspace.
4- To reset the hits count, double-click on the RESET button in the screen.
5- Once testing is completed, you can put the cover back on the DVLC-1. The Lightning Strike Counter kit is now ready for use.
6- You can now disconnect from the DV-Micro unit by clicking on the File-Disconnect drop down menu.
Note that you do NOT need to be continuously connected to the DV-Micro for the lightning counts to be recorded and maintained in the unit. If you wish, the DV-Micro can be connected to a phone line or Network and it can be accessed remotely to check on the lightning strike counts.
Additional notes
Your Lightning Strike Counter kit provides you with much more capability than simply counting lightning strikes at your remote site. It can send you alerts automatically by telephone, email or text message whenever something happens at your site. It can start up backup equipment, monitor doors, temperature, humidity, line voltage, power outage, tower lights and much more.
