    It just clicked when I was going over the manual for the MR52s, you're just putting the address in as the binary number. 0=0, 1=1, 10=2, 11=3, 100=4, 101=5, 110=6, etc. Dip switch 1 is read on the far right side, dip switch 5 is on the far left.

    Binary
    1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024......
    So 5 dip switches means 31 possible addresses.
    The other 3 are system settings.

      32 Possible addresses. O is considered an address also.

      That's different. They usually leave that blank.

    It's Ridiculous being offended by "master and slave" term

      I made sure to look it up in the Electronic Terminology book to back myself up.

      @@lowvoltageghost888 also as an IT guy, it's been a while since I heard that term, last time I heard about it is the time of IDE drives where you could set which one is Master drive and slave drive, but still, normal people being offended by "master and slave" term is still ridiculous, but aside from that your setup is really beautifuly done.

    Why does the master board look so dark on that top left corner

    • @lowvoltageghost888
      @lowvoltageghost888  5 หลายเดือนก่อน

      Some boards come like that, fried and crispy. Jk. But, to be honest, idk, I have installed some boards that are lighter red and darker red. But as long as they work, I'm happy.
      It's funny because that one is a fresh board, brand new.

      Maybe, not sure, that would be a manufacturing question. But yes, I have noticed the coloring a little brighter and faded on some of them.i

    • @ManofCulture
      @ManofCulture 5 หลายเดือนก่อน +1

      Even if the PCBs were manufactured in the same location, there is no guarantee that the color would be the same between two batches. We can also observe color change due to thermal or thermomechanical aging of PCBAs. So having a darker color for the older PCB could be due to an aging effect as well.

    Keep at this, brother. Definitely great presentation. How would you troubleshoot a reader on these broads would be a great video, just some video ideas. Good luck

    So what if you had 2 control panels of a large complex? Do you just connect them via ethernet?

    • @lowvoltageghost888
      @lowvoltageghost888  5 หลายเดือนก่อน +1

      You have 2 options, depending on the infrastructure.
      If the Control Panels (Head-End Enclosures) are in different rooms (MDFs/IDFs), you can connect them via ethernet.
      But if you have them centralized in one control panel enclosure, you can connect up to 32 boards together through RS485 communication on these particular Mercury Boards, which pretty much is 64 doors with access controls.
      There are a lot of factors that need to be considered as well, like the distance of the access controls door to the head-end controler, with 18 gauge wire you can go up to 500ft max. Different systems are different.
      Hopefully that answered the question.

      @@lowvoltageghost888 Cheers I figured it may of been rs485 also. I do industrial automation and it's a mix of both with a fibre backhaul for the IDFs.

    • @lowvoltageghost888
      @lowvoltageghost888  5 หลายเดือนก่อน

      Yes, I have done projects where customers wanted to save money on not having purchasing Master Boards and wanting RS485 run between (MDFs/IDFs) or from building to building with RS485 because some of those building had no network and they just wanted to monitor the entry and exit of employees with access controls, so RS485 was run to them.
      RS485 can travel up to like 4000 ft. Depending on the gauce of wire.
