Screw terminals
The screw terminals provide the followings:
 Eight analog inputs (
CH0H/CH0L to CH3H/CH3L )
 Two analog outputs (
AOUT0 and AOUT1 )
 Eight digital I/Os (
DIO0 to DIO7 )
 One external trigger input (
TRIG )
 One external counter input (
CTR )
 One external clock input (
AICKI )
 One power output (
+VO )
 Six analog grounds (
AGND )
 Four digital grounds (
GND )
Use 16 AWG to 30 AWG wire when makings to the screw terminals.
The single-ended mode pinout is shown in Figure 3.
