Before programming the ACL-8113A to perform the A/D conversion, you should understand the following issues: l A/D conversion procedure l A/D signal source control... -
Page 22: A/D Signal Source Control
A/D Signal Source Control To control the A/D signal source, the signal type, signal channel and signal range should be considered. Signal Type The A/D signal sources of ACL-8113A could be single ended (SE) only. The single-ended mode has only one input relative to ground and it suitable for connecting with the floating signal source. -
Page 23: A/D Trigger Source Control
Signal Channel Control The value of AD channel Control register defines the channel to be selected. Signal Range The proper signal range is important for data acquisition. The input signal may be saturated if the A/D gain is too large. Sometimes, the resolution may be not enough if the signal is small. - Page 24 Define the base address of ACL-8113A card e.g. Base_addr = 0x220; et the desired input channel by MUX control register Base+ 10 2. S e.g. outportb( Base_addr + 10, 2); Trigger the A/D conversion by writing any data to Base+12 e.g.
- Page 25 The formula between the A/D data and the analog value is Direct Binary Coding: Bipolar ±10V: Voltage = (AD_Data * 20) / (4096 * gain) – (10 / gain) Bipolar ±5V: Voltage = (AD_Data * 10) / (4096 * gain) – (5 / gain) Uni-polar +10V: Voltage = (AD_Data * 10) / (4096 * gain) where the gain is 1,2,4,8,16...
