QUADRA-602A Encoder Module Operations Manual
3. DO3 and DO4 can be used as trigger signal of external equipment. It s high/low timng could
be controlled by the host PC.
4. To reduce noises, connect a 47k resistor and a 1uF capacitor between each input of Vin0 to
Vin7 to the AGND nearby the Vin7 termnal hole.
Sample Code
1. Read DI3 and DI4
sInt = USB_GetStatus()
DI3 = (sInt and 4) / 4
DI4 = (sInt and 8) / 8
2. Set DO3 and DO4
tDO1=1: tDO2=1: tDO3 = 1: tDO4 = 0
GetValue = USB_SetControl(tDO4 *8 + tDO3 *4 + tDO2*2 + tDO1*1)
As tDO1 and tDO2 used internally by the board, always set themto high state. Only tDO3 and
tDO4 can be changed as per your specific requirement.
3. Acquiring analog signals
