PC/104 16-bit, 100 kHz ADC Module
|
The DM6430HR is software configurable on a channel-by-channel basis for up to 16 single-ended or 8 differential analog inputs. Overvoltage protection to ±12 volts is provided at the inputs. The common mode input voltage for differential operation is ±10 volts.
A/D conversions are typically performed in 10 microseconds, and the maximum throughput rate of the board is 100 kHz. Conversions are controlled by software command, by an on-board pacer clock, by using triggers to start and stop sampling, or by using the sample counter to acquire a specified number of samples. Several trigger sources can be used to turn the pacer clock on and off, giving you exceptional flexibility in data acquisition. Scan, burst, and multiburst modes are supported by using the channel-gain scan memory. A first in, first out (FIFO) sample buffer helps your computer manage the high throughput rate of the A/D converter by acting as an elastic storage bin for the converted data. Even if the computer does not read the data as fast as conversions are performed, conversions can continue until the FIFO is full.
The converted data can be transferred to PC memory in one of three ways. Direct memory access (DMA) ransfer supports conversion rates of up to 100.000 samples per second. Data also can be transferred using the programmed I/O mode or the interrupt mode. A special interrupt mode using a REP INS (Repeat Input String) instruction supports very high speed data transfers. By generating an interrupt when the FIFO’s half-full flag is set, a REP INS instruction can be executed, transferring data to PC memory and emptying the FIFO buffer at the maximum rate allowed by the data bus.
The mode of transfer and DMA channel are chosen through software. The PC data bus is used to read and/or transfer data to PC memory. In the DMA transfer mode, you can make continuous transfers directly to PC memory without going through the processor.
