| IPAC4 and LEDs - Question about power |
| << < (3/5) > >> |
| AndyWarne:
On the 9-pin header on the I-PAC there are outputs for the 3 keyboard LEDs. But also on the header there are 5V pins which are permanent if you just want to light LEDs all the time. Andy |

Thanks Andy - really appreciate the response. So I should just connect my LEDs to the 5v and the ground so they are always on? Also, do you know when the USB Ipac4's will be in stock again? I originally ordered a PS2, but now I need a USB as I will be using a machine without PS2 ports on the board. I read elsewhere you did not think it was good to use the PS2 to USB adapters. |
| AndyWarne:
Yes you can connect the LEDs to 5V and ground but unless they are 5 volt LEDs they will need resistors in series. The value of the resistor depends on the LED but as a general rule use 220 ohm. All I-PACs are dual interface USB/PS2 devices. Using an adaptor is fine. What you cant do is use a converter, of the type which is designed to convert a PS/2-only device to USB. So you can either use our cable or something like this: |
| bratwurst:
Is it possible to take a ps2 cable and a USB cable and splice them? |
| bratwurst:
I ended up grabbing a USB (female) to PS2 (male) and spliced it with a USB cable. I used the USB to PS2 instead of a normal PS2 cable as I hoped that the wire colors would match up for me. Worked right away. |
