Hardware installation, jumpers, and matching terminal boards

1. Unboxing and anti-static standards

The board contains a static sensitive chip, and it must be operated with an anti-static wristband and on an anti-static pad; Check for any transportation damage before powering on.

Kit standard: PCI board, driver CD, this user manual, software installation guide.

2. Hardware installation steps

Power off the entire machine and external devices, open the chassis;

Set the board jumper in advance according to the requirements;

Choose a white/beige 32-bit PCI slot, touch the chassis to release static electricity, hold the edge of the card and insert it into the slot, and tighten the fixing screws;

Windows system automatically plug and play hardware recognition upon startup, follow the instructions on the driver CD to install the software.

3. Definition of CN1 37 pin interface pins

Contains 8 voltage outputs V0-V7, 8 current outputs A0~A7 (only 6308A), 4DI/4DO, analog ground AGND, digital isolation ground DIGND/DOGND, external reference ExtVref, ± 15V onboard power supply, distinguishing between analog and digital isolation circuits to avoid interference.

4. Jumper configuration rules

The underlying address of registers and the working principle of hardware

1. I/O address mapping (BIOS automatically assigns base addresses)

Base address+00~0E: 8-channel 12 bit DAC output register (write only); 00H bit 0 is the DA data transmission status bit;

Base address+40H: Digital IO register (write=DO output, read=DI input+DO read back);

The remaining addresses are reserved for backup use; The PCI configuration register is automatically allocated by BIOS plug and play, and manual modification of the base address/interrupt is prohibited.

2. Principle of Analog Voltage Output

12 bit unsigned data from 0 to 4095 corresponds to full scale:

±10V：0= -10V，2048=0V，4095=+9.99969V；

0~10V：0=0V，2048=5V，4095=+9.99969V；

Custom 0~Vref: 0=0V, 2048=Vref/24095=Vref;

There is a 13 μ s delay in DAC serial transmission, and the software needs to read the status bit to confirm the transmission is complete before issuing new data.

3. Principle of Current Output Conversion (6308A Exclusive)

On board XTR110 V/I chip, each voltage output directly drives the corresponding current source. The software function switches between three output ranges of 0-20mA/4-20mA/5-25mA, with a typical load of 250 Ω.

4. Principle of isolated DI/DO circuit

DI: 2.4k Ω current limiting+bidirectional voltage regulator protection, optocoupler isolation of host side and on-site signals;

DO: Open collector optocoupler output, no built-in pull-up, external resistor must be connected in series for power supply.
