NEW cab with Button LED

[Blackus]

Hi
I have a cabinet with the 14 ice button and a ice trackball all with led s.

I have 3 LED-WIZ but i don't have understood well like connecting them. You can help me?

So.. I must connect every cable (3 for every led) to input that they go from 1 to 32, then a fourth cable of every led (that with a red line) I go connected to the GND.

They then remain USB 5V and the four taken (1-8, 9-16, 17-24, 25-32). To what they serve? Where I have to connect ??

The bank voltage select lets you use the +5V USB or and external voltage source.   You can only get 500 ma from USB so if your total LEDs are more then that you need an external 5V supply.

And the 4 connectors on the left to that they serve?

 Care instead the +5V as I make knowing if the usb it is enough or if I have need of the +5v?  It convene to me to prescind to connect the +5v for sure being?

[BobA]

Doing a calculation on your LED setup you need 20 ma for each led color so RGB is 60 ma each x 15 = 900 ma.   You need to drive 45 outputs so you need 2 LEDwiz boards to do that.   If your outputs were spread evenly between 2 boards and you are just under the max of 500 ma per board.   As long as your computer or powered hub can provide the full 500ma per usb outlet you can get away with using the USB power and do not need an external power source.  So wire 7 LEDs to 1 LEDwiz and 8 LEDs to the other.

ok thanks.
Ok perfect therefore dividend the 14 1 LEd rgb on the two cards I do not have problems and I do not have need of the 5v. Good.    For the connector to sx of the board? To what They serve?

[BobA]

Not sure what your question is can you reword it?

[Blackus]

uhm I have not understood well because 4 are taken that they group the other outputs.

what sx are you refering to?

So in this image:

1. is the connect for the external +5V

Since I have no direct experience with the new LEDWIZ I suggest you contact them as it says in the doc before connecting the bank selects. The original boards defaulted to USB supply apparently the new one does not.


This is from the GGG Documentation

This new version of the LED-Wiz PCB has been designed to allow direct access to the suppression diodes of the output driver chips on a per chip, or “8-output
bank”, basis. This gives the user the capability of running inductive loads (relays, coils, solenoids, etc) with as many as 4 different voltages per board. The positive
power line must be connected to any other part of the LED-Wiz board, and all devices attached to any bank of outputs must share the same voltage
requirements. For operating only LED’s, it may not be necessary to be concerned with the “Bank Voltage Select” terminals at all. However, any inductive loads (or
loads which you can’t identify as inductive or not) must have the positive voltage line connected to the appropriate “Bank Voltage Select” terminal for the output
bank which the negative lines of the devices have been connected. In cases where only one device voltage is being used, it is permissible to simply link all of the
“Bank Voltage Select” terminals together and then connect them to the positive line of the power supply. This configuration was the default state of the original
LED-Wiz when shipped. Note: If this section is not understood by the user, it is highly recommended that an email be sent to techsupport@groovygamegear.com
for clarification. Improperly connecting positive voltages to the LED-Wiz will result in destruction of the LED-Wiz and and any devices attached, including your computer so be safe and ask questions if necessary.

If only the USB port power is to be used to power external devices, be aware that it can supply only 5vDCpower with a total current delivery of about 500ma. Larger
5v DC loads, like small incandescent lamps and relays, or large numbers of LEDs, should be connected to the PC Power supply (Figure 2) through a cable with an in line fuse.
The use of a fuse is strongly recommended! This type of fused cable is not included but can be purchased at your local electronics store. Be sure to
select the proper fuse size for the load you have connected to the device! Too large a fuse and it won’t protect anything, too small and they will keep blowing. Keep
all of your wiring clean and tidy. The most important thing to keep in mind when wiring your project is safety first and a well thought out approach will help ensure
this. See the diagrams below, and on the back of this page, for wiring examples.
