Hardware installation steps (anti-static+PCI/cPCI process)

1. Pre installed anti-static mandatory regulations

The board is sensitive to static electricity, and must be operated with a grounded anti-static pad and an anti-static wristband; Only hold the edge of the board and do not touch the components; Damage is strictly prohibited from being powered on.

2. Packing standard list

DA board, accompanying CD, paper manual; The R-version cPCI model comes with an additional rear IO backplane; Contact the dealer immediately if the received goods are damaged.

3. Software installation sequence

Insert Linghua Integrated CD;

Choose one to install driver: New generation DAQPilot (recommended)/Old PCIS-DASK compatible driver;

Install DAQMaster device management tool to identify hardware.

4. Hardware installation process

PCI desktop board

Power off the entire machine and release static electricity from the human body;

Select the white 32-bit PCI slot, smoothly insert and secure the baffle screw;

CompactPCI industrial control chassis board

Turn off the power of the chassis;

Remove the slot baffle and insert the card for locking; The R model is equipped with an additional rear IO adapter backplane.

5. PCI Plug and Play Resource Allocation

The board is equipped with PLX PCI9052 controller, and all interrupt and IO base addresses are automatically assigned by BIOS, and manual modification is prohibited; Troubleshooting BIOS interrupt settings for boot resource conflicts.

Full platform software support system (unified with 723X manual software architecture)

1. The two major systems of Windows drivers

Main recommendation: DAQPilot (next-generation task-based driver)

Unified API, compatible with Linghua’s full range of DAQs (AI/AO/DIO/counters);

Supporting DAQMaster graphic tools: hardware recognition, driver management, DAQ task editing, board calibration;

Supports all mainstream development environments such as VB.net/C #/VC+/Delphi, compatible with Win98/2000/XP/Vista 32/64 bit.

Compatible with old projects: PCIS-DASK kernel driver

32-bit. sys low-level driver, supports 64 bit system WOW64 compatibility layer, Vista digital signature; Official new projects are not recommended for use, only legacy programs are compatible.

2. Linux driver

DASK/X series cross platform driver, API consistent with Windows DASK, compatible with PCI/cPCI/PXI capture cards, available for download from the official website.

3. Complete adaptation of third-party software

MATLAB (DAQ-MTTLB): an official collaboration plugin of MathWorks, which directly calls Linghua hardware and supports high-speed digitizers;

Agilent VEE (PCIS-VEE): Visual process programming interface, compatible with VEE4.5;

ActiveX Control (DAQBench/PCIS-OCX): Targeting VB/VC/SCADA upper computers, it provides trend, alarm, and OPC docking components.

Bottom level hardware registers (specifically designed for low-level development)

1. PCI three-layer register architecture

PCR (PCI Configuration Register): BIOS allocates interrupts and IO base addresses;

LCR (Local Register): The underlying parameters of the PLX9052 chip do not require any operation for regular development;

6208/6216 dedicated IO register, all 16 bit access.

2. IO address mapping (base address offset)

AO output registers: 0x00, 0x02… Each 2 bytes corresponds to 1 DAC; 6208 is only valid for channels 0-7, while 6216 extends to V15;

AO status register (offset 0x00 read-only): D0=Data_Send bit, set high during DAC serial transmission, must wait for this bit to become low before writing the next set of voltage values (fixed 2.2 μ s per transmission);

DO register (offset 0x40 write): Low 4 bits control DO0~DO3;

DI register (offset 0x40 read): The high 4 bits read DI0~DI3, and the low 4 bits read back the DO output status.

3. DA digital quantity → voltage conversion rule

16 bit signed encoding, unipolar mapping ± 10V:

0x8000 = -32768 → -10.0000V

0x0000 = 0 → 0V

0x7FFF = +32767 → +9.99969V

Board testing and calibration tools

2. Factory calibration mechanism

Calibration equipment: 6-and-a-half-digit high-precision digital multimeter DMM;

Process: Traverse all 16 bit encoded outputs, collect real voltage to generate compensation table and store it in onboard Flash;

Function: Automatically correct gain and offset errors, optimize linearity;

Maintenance suggestion: recalibrate every year and contact the manufacturer’s after-sales service for operation.

Chapter on Safety Regulations

Installation/maintenance must be completely powered off; Stay away from liquids and high temperatures, ensure ventilation;
