    Default Proposed wiring standard for Mighty Mini Flood and Controller

    Denny brought up a good point that we should standardize the wiring and connections for the Mighty Mini Flood and controller. So, here is how I think we should standardize. The first number is the DC controller channel. The first color is cat5 wire color and second color is the RGB LED color. The white wire in each twisted pair is the + lead of the channel.

    1 orange red
    2 green green
    3 blue blue
    4 brown white
    5 orange red
    6 green green
    7 blue blue
    8 brown white
    9 orange red
    10 green green
    11 blue blue
    12 brown white
    13 orange red
    14 green green
    15 blue blue
    16 brown white

    keystone cover (location was picked due to the channel wiring location on controller)
    upper right in box is dc controller channels 1-4
    lower right in box is dc controller channels 5-8
    lower left in box is dc controller channels 9-12
    upper left in box is dc controller channels 13-16.

    The keystone location is really not necessary as long as the location is labeled.

    The wiring for the LEDs and DC controller are as above. However, the Cat5 connectors are wired to TIA/EIA-568-B common Ethernet cable standard. Click on the image to expand. This wiring arrangement is to allow standard ethernet patch cables to be used between the Mighty Mini and DC controller.

    That's not a bad idea considering some of us may need to borrow one or two in case one goes out.

    Bump. This is for the TASL guys building Mighty Minis just in case you want to share emergency stuff in the future. Plug and play replacements are the best way.

    I know I'm late replying to this note...

    However, due to the fact that some DC controllers that are coming out in the DIY community also use the RJ45 connection method, you may want to rethink a few of your connections.

    Why, you ask? Because the "normal" TIA485A wiring of Cat-5 cables has the green/green-white pair split, with the blue/blue-white pair in the middle. This means that if you are using the pins of an RJ45 connector, you'll have the following:

    ch 1 - org/org-wh - pin 1/2
    ch 2 - blue/grn-white - pin 3/4
    ch 3 - grn/blue-white - pin 5/6
    ch 4 - brown/brown-white - pin 7/8

    The + of each channel is on the white wire of the pair.

    Just a thot.

    It never occurred to me that we should use the TIA/EIA-568-B common Ethernet cable standard. The off the shelf cables are crossover style. Thank you Mark. I will post the correct colors. This change will allow store bought cables to be used with the floods.

    And to clarify the selection even further, the white wires for each pair are on the lower pin - i.e. orange-white is pin 1, orange is on pin 2.

    For those that may choose to use Renard controllers, or even Grinches or other DIY boards with external SSRs, the remote SSRs boards also assume this wiring standard, with pins 1,3,5,7 usually tied together at 5 V, and pins 2,4,6, and 8 being the control signal being pulled low when active. So it follows the same standard.

    Walter and I are currently building the Mighty Minis and DC controllers as stated above. If you want to be able to share equipment with other people in the Raleigh area, then follow the standard and our equipment will be plug and play interchangeable.
