Needing help with Alpha faders and buttons
Needing help with Alpha faders and buttons Posted on: 01.04.2011 by Hui Santacroce Hello, FriendsIm new to this but im diving in head first I bought some faders from the fine folk over at DJTT, and i'm trying to figure out how to find out which pin is which on the bottom of the fader. I've got pin(s) 1 2 and 3 How do i find out which one is the ground, power, and output to connect to the midi fighter. Also I bought extra buttons, How do it hook those up to the midi fighter One connection to ground and one connection to output? Thanks in advanced dany http://soundcloud.com/fndmntl | |

| Hunter Renslow 05.04.2011 | Put the fader in the centre and check the pins with your multimeter.The ones that read 10k are your ground and power and the third one is your input.

the colours look like 10k resistors which are perfect

| Hunter Renslow 07.04.2011 | No problem,hope you get it working!! |
| Hui Santacroce 06.04.2011 | Did you connect it to an analogue input?Did you connect the 3 pins(gnd,5v and input?) Are your connections good,I got wierd glitches from a bad solder joint.[/QUOTE] Ya, i guess i'll check the connections again Thanks a lot sidetrakd |

| Hui Santacroce 05.04.2011 | Thanks guys, you've shed some light. BUT im still in the dark DJTT is understaffed and i'm waiting on the specs of the faders so.... After blowing up one fader Using my multimeter measuring @ 200k i've found readings (0 - 10.5) runs through pins 1 and 2 2 and 3 Does that give enough information as to what gets attached to what? as far as the buttons are concerned I followed this diagram +------o +5v | # 10k resistor # | +------o DigitalIn | / switch / | | +------o Gnd but im wondering if i bought the wrong resistors, I never specified pull up or pull down. the colour code looks like brown, red, black black, brown Do i have the wrong ones? Also, I got an analog pot to work but the Midifighter was sending all kinds of other data and would only stop if i (what seemed like) grounded the Motherboard by placing my hands on the metal casing of the usb port. Did i short out the analog inputs? I feel like im in over my head with this stuff. |
| robert chanda 01.04.2011 | If you have a multimeter, you can just measure which is which. |
| Harley Hendzel 01.04.2011 | Also, to make things easier, you can install female headers into the expansion section |
| Harley Hendzel 01.04.2011 | Connecting to the digital inputs: http://www.djranking s.com/community /showthread.php?t=12494 Connecting to the analog inputs: [step 6]http://www.djranking s.com/2010/02/0...sis/#more-4747 as far as testing the fader to see, do you have a multimeter for electronics? or maybe send an email back to djtt requesting the specs for the fader. |
