ADLINK cPCI-7432/7433/7434 isolated I/O card

Get Interrupt Status (cardNo,&stat1,&stat2)

Clear interrupt and write any value to Base+0x08

LED Control (R Version) _7432R_LED (cardNo, LED_Sata)

Read slot number (R version) _7432R_SlotNo (cardNo,&lot)

Common troubleshooting

Possible causes and solutions for the phenomenon

Input cannot read signal COM terminal wiring error; Check the COM connection (common ground/common source) when the input voltage is below 5V; Measure input voltage

Output unable to drive load VDD without power supply or insufficient voltage; Connect the external power supply with a load current exceeding 5-35V; Confirm that the load current is ≤ 500mA

Output constant on or off output type (common ground/common source) does not match program logic. Check hardware model (with P suffix) and adjust write logic

Interrupt not responding, interrupt source not enabled; IRQ conflict check Set-INT_Control and INT_Snable; Check the idle IRQ of the system

After cPCI, the line card cannot recognize the insertion of non-standard backboards or insufficient power supply in the slot. Only ADLINK or compatible cPCI backboards are used; Check the power supply of the chassis

Multiple card port recognition confusion, incorrect calling of Initial function, traversal of all cards using loop call _743X_Initial, obtaining the number of cards through existCards
