4.15 - VoltsToBits [U12 Datasheet]

Converts a voltage to it’s 12-bit (0-4095) binary representation. No hardware communication is involved.

Bits=(4096*((Volts*Gain)+Vmax))/(2*Vmax) where Vmax=10 for SE, 20 for Diff.

Declaration:

long VoltsToBits ( long chnum,
long chgain,
float volts,
long *bits )


Parameter Description:
Returns: LabJack errorcodes or 0 for no error.
Inputs:

• chnum – Channel index. 0-7=SE, 8-11=Diff.
• chgain – Gain index. 0=1, 1=2, …, 7=20.
• volts – Voltage.

Outputs:

• *bits – Binary value from 0-4095.
