    I looked at the board in my SP Lite and figured out how to do a fairly painless install of a remote to control feed and oscillation.


    Requires a 2 button (or more) remote ($20) Relays on the remote can have a low amperage rating. Must be a 12 volt remote.

    Edge models without a remote have 2 pairs of pins that are soldered together (jumped). They are located under the remote header (oher side of board)

    Simply desolder or snip the solder between the pins and hook up your remote circuit. No wires to cut or move.

    Looking a the board from the side with the header and holding it with the knobs facing you, here is how it should be wired

    from top to bottom

    Pin

    1) to Common on osc relay (on remote)
    2) to NC contact on osc relay
    3) to Common on feed relay
    4) to NC conact on feed relay
    5) to negative (-) power to remote
    6) to positive (+) power to remote (12 volts)

    Works perfectly.....you can buy a 6 pin plug if you want a neat installation....Mouser , Digikey and others have them

    The remote will work exactly like the Sport model. When you power down and then turn the machine back on, feed and sweep will work without the remote. use the remote to shut them off after the machine is powered up. If you want to ONLY use the remote, wire to the NO rather than NC contacts

    Here are some pictures

    in the picture below (back of board), notice the rectangle around the 2 pairs of pins that need to be unjoined. this can be done with small side cutters and/or a small soldering iron. If you look closely at this area of the board, you can see that they were hand soldered. Don't scrath the board, if you ever need to send it back.

    In the picture below, I outlined the remote header. in this view, from left to right, you would hook up per my first post, (from top to bottom) Top would be left in this picture.

    I'll dig up the p/n for the header connector, but I just used a pair of 3 pin connectors as found on a model airplane or rc car servo. (same pin spacing and size)

    ....

    Go to SP website and look at owner's manual for the Lite. this will show you how to remove the battery, but you will have to take the blue cover off to install the larger battery.

    Look at owner's manual for sport/star to se how to change or install the bigger battery.

    You either have to make a larger hold down bracket, or some have tie wrapped it in???

    The bigger battery is equivalent to a 'Universal Power 12210'

    Shop it out...I paid just under $40 for mine.

    I also bought a 5 amp quick/smart charger online for $50 plus shipping

    If you are older, you will definitely notice that extra weight

    I have been wondering the same thing. This is an old thread but I'll post back here if I find one.

    I could be wrong but I'm pretty sure KF2510-6P is what we are looking for. My guess is that OP used something like 2 of KF2510-3P he had lying around.

    Thanks,

    Do you know where to put the remote circuit board inside the machine? And pre drilled holes to fix it on the box?

    If you have a Lite and enjoy electrical projects - How happy are you with the pace adjustment control? So far I find on mine that I want to use settings only between 3.9 and about 4.4. That is a very narrow range of the total range of adjustment of 1.0-9.0. To adjust it I get down on my knees to reduce the parallax. It feels like a resistance pot. ? If so, would two pots in series give a coarse and fine adjustment? Would one of those pots that have incremental clicks and digits, 1-100, work? (I also turn mine down to the slowest speed to turn it on or off to minimize motor current in case that might be easier on some electrical components, probably unnecessary. )

    I have the remote and it added $150 to my costs. It works well.

    Wonderful job rjw!

    How did you figure out which pin pair's role? There is little (simply no) documentation on this sort of thing though.

    Just puchased:

    SP Edge Lite $699

    DC12V 2CH channel Wireless Remote Control Switch System $12.18 (*bay)

    3 pcs KF2510 Connector Kits 2.54mm Pin Header + Terminal + Housing KF2510-6P $1.49 (*bay)

    If it works I'll have a $850 value for under $715. I could add a $40 battery if I need to to take it up to STAR level at $950.

    I did it

    I just wanted to update that I successfully acomplished this upgrade on the SP lite! Some details:
    1) using a solder sucker I quickly desoldered the two jumpers.
    2) I soldered some 22 gauge solid core hook up wire to the pins from the header connector I bought (above). This took a while and is delicate soldering work. If I was to do it again I would use 20ga stranded to prevent breakage.
    3) Inserted the pins into the header connector in the order above.
    4) Connected the wires to proper screw terminals on the remote module, plugged in the header connector to the board and installed jumper on remote module for toggle operation.
    5) Used stick on velcro to secure the remote module to the inside ceiling of the SP, replaced the control panel, flipped the manual osc to on, and tested.

    If you could find the 6 pin header connector with wires already on it or 2x3pin like the OP did, this is a super easy upgrade. No need to take the unit apart like with a battery install. I never even had to disconnect the board like in the above pics.

    I love this machine and this cheap easy upgrade!

    Do you know any used electric may have that 6 pin plug?

    fwiw, I have a fried board (one of those two large square things toasted) if anyone can use before I discard.

    PC fan connectors use the 3 pin 2.54mm connectors to plug into the motherboards. Also, my old directivo uses them on the fans. Dig up two old PC fans and you're in business.

    Here is a source for new 6 pin wired.
    Search the bay for "2510 2.54mm 6-Pin JST Connector Plug w/.Wire "

    Note that this is 26AWG wire (on the listing I see) which should work but is very thin wire. I broke my solid core 22AWG a couple of times after fitting it into the 6 screw terminals on the remote module. Stranded wire would have been better, more flexible, allowing you to use a thinner guage.

    This means the only coldering required is a quick desolder of the jumpers. Which took me less than a minute because I had one of these:
    "Blue Sucking Vacuum Desoldering Pump Solder Sucker Remover Tool" (6 bucks on amazon) (I tried first the small side cutter method on the soldered jumpers but it just made a mess. Desoldering with a sucker or wick is the way to go, IMO.)

    Thank for the information

    But do you know where to find these in local store. Went to radio shack but didnt see the connector and remoter. Not easy to buy from Bay.

    Sorry I don't or I would have looked. Radio Shack seems to carry a lot less of that type of stuff than they used to.

    Question for Momolabs

    Did you mean you didn't even have to take off the blue plastic body? How could that be possible?

    Just saw this old post and want to add a remote to my silent partner. Can someone verify these are the pins that I need to desolder (two big rectangles)?
