Product Technical Specifications and Characteristics

Core advantages

The core design of this card is to combine high-speed fiber optic communication technology with modern computer bus architecture. Its main characteristics include:

High speed data transfer: Using DMA (Direct Memory Access) technology, measurement data can be directly written into system memory without CPU intervention, significantly reducing CPU load and improving data processing efficiency.

Multi protocol support: Automatically detects and supports all current and traditional ibaNet communication protocols, including 2 Mbit/s, 3.3 Mbit/s, 5 Mbit/s, 32 Mbit/s, and 32 Mbit Flex protocols, ensuring compatibility with new and old devices.

High signal density: A single fiber optic link can transmit up to 512 analog signals and 512 digital signals, with a sampling time range from 10 microseconds to 2 milliseconds, meeting a wide range of application requirements from low-speed process monitoring to high-speed transient capture.

Plug and play: supports hot swapping, convenient for on-site use.

Power consumption and indication: Powered through the ExpressCard slot, the typical power consumption is only 1.5 W. The board integrates 4 LED status indicators to indicate operating status, link speed, and error messages.

Environmental conditions:

Working temperature: 0 ° C to 50 ° C (32 ° F to 122 ° F)

Storage/transportation temperature: -25 ° C to 70 ° C (-13 ° F to 158 ° F)

Hardware installation and driver configuration

IbaFOB io ExpressCard supports plug and play, which can be installed or removed while the computer is running without shutting down.

Installation steps:

Insert hardware: Insert the card smoothly into the ExpressCard slot of the laptop until it clicks into the internal connector. After correct insertion, the green LED will start flashing and the red LED will briefly light up and then turn off (if the driver is not installed, the red LED will continue to light up).

Driver installation: When first inserted, the Windows system will pop up the "Discover New Hardware" wizard. Please follow the prompts to complete the driver installation. To ensure that the driver is correctly recognized, it is recommended to install ibaPDA-V6 (≥ 6.24.0) or ibaLogic-V4 software before inserting the card.

Verify installation: After installation is complete, you can check whether the card is listed correctly through Windows Device Manager. If the card does not appear, it indicates that there is a problem with the driver installation and you need to contact IBA technical support.

Removal steps:

Disconnect the fiber optic cable.

Gently push the card to unlock it, then carefully pull it out of the slot.

Deep analysis of software configuration and application

Configuring the card in ibaPDA-V6 software is a crucial step in achieving data collection.

I/O Manager Configuration

Start the ibaPDA-V6 client and go to "Configure ->I/O Manager". Select ibaFOB io ExpressCard in the left tree structure.

Configuration tab:

Interrupt mode: For single card laptop applications, "Master mode internal" is usually selected.

Enable status: Check the "In use" option to enable ibaPDA to recognize and use the card.

Onboard watchdog: optional feature. After activation, if data collection stops for more than 2 seconds, the board will generate an alarm message, set the output value to zero, and light up the red LED indicator light. This function can be used for external system monitoring of the operational health of ibaPDA.

Information tab:

This tab provides board hardware information and loaded firmware versions. Important reminder: Firmware updates must be carried out under the guidance of the IBA technical support department and should not be operated arbitrarily.

Link status monitoring

The software interface provides detailed diagnostic information for each fiber link (Link 0). These pieces of information are crucial for troubleshooting communication failures.

Communication status area:

Communication status: Displaying "OK" indicates that the fiber optic communication is normal, that is, the received data message matches the mode of the link configuration.

Detected link protocol: Display the link protocol automatically detected by the board (such as 3.3 Mbit/s, 32 Mbit/s, or "?").

Telegram/Error counter: Display the number of correctly received and erroneous messages (such as checksum errors) respectively. If the error counter continues to increase, it indicates interference or poor connection in the fiber optic link.

Detailed analysis of diagnostic information (differentiated by protocol):

3.3 Mbit/s or 2.0 Mbit/s mode:

FO signal strength: displays the strength of the fiber optic input signal (range 0-255), with higher values indicating stronger signals.

Device ID: Display the ID of the last device on the link.

5.0 Mbit/s mode:

Device firmware date: Displays the firmware date of the connected device.

Gain and filter table: suitable for ibaPADU-8-ICP devices, displaying their configured gain and filter settings.

32Mbit Flex mode:

Mode: Indicates whether the connection mode is "Ring" (bidirectional closed loop) or "Open chain" (open chain, only input connection).

Round trip delay: In a closed-loop fiber optic ring, the cycle time of data packets is related to the number of devices in the ring.

Image generation area:

This section describes the status of the data buffer that the board writes to the system memory through DMA.

Images processed at interrupt: Displays the number of images available in the DMA buffer at each interrupt.

DMA buffer empty/Dropped images: These two counters are key to diagnosing system performance bottlenecks. DMA buffer empty increment indicates that the buffer is empty, usually occurring when the fiber link is disconnected. Dropped images increment is a serious warning, indicating that the DMA FIFO of the board is full and unable to transfer data over the PCI bus. This suggests that the PCI bus is overloaded or the system is not responding in a timely manner.

Operation mode and device compatibility

The flexibility of ibaFOB io ExpressCard is reflected in its support for multiple operating modes, enabling it to connect almost all iba field devices.

Troubleshooting and LED indicator lights

The four LED indicators on the front end of the card provide intuitive hardware status feedback:

Run (green): Flashing indicates that the power is turned on and the channel function is normal; Constant shutdown means that the controller has stopped (due to hardware failure).

Link Slow (yellow): Always on indicates correct message reception at 2/3.3/5 Mbit/s; Flashing indicates receiving message but configuration mode does not match; Constant extinction indicates that no message of the corresponding rate has been detected.

Link Fast (white): Always on indicates correct message reception at 32 Mbit/s; Flashing indicates receiving message but configuration mode does not match; Constant extinction indicates that no 32 Mbit/s message has been detected.

Error (red): Constant light indicates watchdog alarm; Flashing indicates running 'Golden FPGA Flash Rescue mode' (firmware recovery mode); Constant extinction is a normal state.

Common problems encountered in software configuration or use, such as abnormal signal reception, data loss, etc., can be quickly located by combining the above LED status with software diagnostic information (such as error counters, DMA buffer status).
