    Hi,

    I was wondering if you guys could share close up pictures of your SCN5 connexion box ? I am very newby with electrical circuits and would like to see what are the options I have ...

    I bought this breadboard to do the connexion job ... Is it a good option ?

    http://www.cn-cheery.com/show_en.php?id=360

    Is there any procedure link like 'SCN5 circuit connexion for dummies' ?? :)


    Thx!

    Essentially all you need is a USB to RS485 adapter, or a Serial to RS485 adapter. This thread expalins it all: viewtopic.php?f=25&t=1083

    You can build your own, but for the price, most people find an off the shelf adapter more cost effective.

    Thx Bernard, I already red this threat a couple of times ...

    It's more for the resistance and diode connexions ... Do I really need them ? I will not connect any kill switch ...


    Thx!

    If you are not using a kill switch then the diodes are not necessary.

    If you actuator cables are 3ft. (1m) or less, then you do not need the resistors.

    Afair, the diodes are an overvoltage protection in the ILK (killswitch) circuit, to prevent ILK damage, as the ILK transistors are very overvoltage sensitive. So I guess they should be recommended whether kill switches are used or not.

    Thx for answering.

    But if the actuators are connected to a power supply with over surge protection, wouldn't that be enouph ? or it's just in case the over surge protection fails ...?

    You can always add the diodes as an extra precautionary measure, but in 12-15 different adapter / power supply combinations that I've tested over the last few years, I've not had problems as a result of not including the diode.

    That being said, I do agree that the ILK circuitry is sensitive to overvoltage and IMHO, a switching, over-volt protected power supply is a MUST.

    Anyone willing to share close up pics of you SCN5 power connexions? (connector extension to power supply)


    Thx!

    ... All right, I figured it out... There are probably other better ways to do it but this is my first circuit ever made and more importantly it's working! Both actuators are detected with no errors by the profiler.

    Feel free to comment ...

    If it can help other newbies with their connexion board ... :)
