====== Control Panel AIN_4 & AOUT_4 v1.2 ======
===== AIN4 - AOUT4 v1.2 TOP =====
{{:phatline:Control-Top.jpg?800|}}\\
**BOM:**\\
[[https://www.taydaelectronics.com/electromechanical/switches-key-pad/push-button-switch-dc-30v-0-1a-dpdt-7x7mm.html|8x Switch better take mouser ones...]]\\
LED5-8: Normal LEDs\\
LED1-4: Bipolar LED comman Anode\\
VR1-4 AOUT4: 10K Lin\\
VR1-4 AIN4: 100K Lin\\
SKT1-4: 3,5 mono Jack\\
JP21: Optional Clock Input from SKT5 (then don't set G1_G5 on the backside) \\
J1: Routes gate outputs from a standard DOUT pinheader to SKT 5-8 according to solder jumper pairs Gxx\\
===== AIN_4 v1.2 BACK =====
{{:phatline:Control-AOUT-back.jpg?800|}}\\
**BOM:**\\
RN1: 100k iso 652-4816P-1LF-100K\\
SJ 1-4: let them unsoldered\\
SJ 5-8: solder a 1K 0603 SMD Resistor from the Round PAD to GROUND- to avoid Floating\\
Diodes: 1N4148  >  only Stuff in AOUT4 Usecases\\
IC2: 74LV14H (SOIC14)\\
C2: 100nF Kerko\\
The Rest: cant remember...Resistors and Caps...\\
\\
about G5_G1, G2_G6, G4_G8, G7_G3:\\
J1 you connect to a DOUTx4 output, which deliver 8 DOUTs on 1 shroudet header\\
But we only use 4 DOUTs on the Controlboards... with this jumpers you decide which one!\\
IF you use a CLOCK coming from J21, then dont set G1_G5!\\
===== Front-Panel for AIN_4 v1.2 =====
i measeured the PCB, and made a drawing in order to create a hand-drilled Frontpanel...
so dont take the values as 100% true...:\\

**LABELS:**\\
linke Schalter: offset (uni/bipolar)\\
rechte Schalter: range (+5V/+10V insgesamt)\\
\\
**Deswegen folgende Möglichkeiten für Ein- bzw. Ausgänge:**\\
0 bis +2,5V\\
0 bis +5V\\
-2,5 bis +2,5V\\
-5 bis +5V \\
