ADLINK PCI-9112 Multi functional Data Acquisition Card

Data is read and written through programmable I/O, suitable for low-speed logic operations such as controlling indicator lights, relays, and reading switch status.

All digital I/O pins are led out through 37 pin D-Sub connectors (PCI) or 100 pin SCSI connectors (cPCI), and some signals are also provided through 20 pin flat cable connectors (CN1/CN2).

4.2 Universal Timer/Counter

1 channel, 16 bit resolution.

Reference clock: 2 MHz internal clock, while supporting up to 10 MHz external clock input (via EXTCLK pin).

TTL compatible, can be used for frequency measurement, pulse counting, PWM generation, or as a frequency divider source for sampling clocks.

6.2 System Integration Precautions

Analog input wiring:

Differential mode should use twisted pair shielded wires and connect the shielding layer to AGND.

High impedance input (1G Ω) is easily affected by noise, and the length of the signal line should be shortened as much as possible.

Avoid suspending unconnected inputs (not explicitly mentioned in the manual, but high impedance input suspension may introduce noise, it is recommended to ground or connect to a fixed level).

Overvoltage protection:

Continuous ± 35V overvoltage protection can prevent most misconnections, but exceeding this range continuously may still damage the card.

DMA transfer:

Ensure that the system motherboard supports PCI bus master control and that this feature is not disabled in the BIOS.

In Windows, the driver automatically allocates DMA memory without user intervention.

Calibration cycle:

It is recommended to calibrate every 6-12 months (depending on environmental stability), and high-precision voltage sources can be used in conjunction with calibration software.

7.3 Programming Process Example

Call _9112Initial (or W_9112Initial) to initialize the board and return the base address and IRQ.

Configure analog input channel mode (single ended/differential) and gain.

Set the sampling frequency (via internal timer or external clock).

Call _9111_AD_SMA_Start to start the collection process (specifying the number of channels, sampling points, and buffer address).

Loop call _911_2AD_SMA_Status to check the transmission progress.

After the data transmission is completed, process the data and call _9111_AD_SMA_Stop (if stopped early).

Comparison and selection between PCI-9112 and cPCI-9112

Comparison item PCI-9112/9112A cPCI-9112

Bus interface standard 32-bit PCI (3.3/5V) CompactPCI (3U)

Size 175 × 107 mm 160 × 100 mm

Connector 37 pin D-Sub+20 pin flat cable 100 pin SCSI-II

Power consumption (+5V) 460mA (9112A) 600mA

Applicable scenarios include industrial control computers, desktop PC expansion rack systems, and high reliability backplane card insertion

The terminal board accessories are abundant (DIN-37D, ACLD series) and relatively few (DIN-100S)

Selection suggestion:

If the system is a standard PCI industrial computer or desktop computer and cost sensitive, choose PCI-9112/9112A.

If you need CompactPCI chassis hot swapping, backplane synchronization, or high-density installation, choose cPCI-9112.

Analog output calibration range selection: If commonly used 0-5V output, choose PCI-9112; If 0~10V is commonly used, choose PCI-9112A.
