Allen Bradley 1784-PCIC

Technical Specifications

The Allen Bradley 1784-PCIC is a PCI communication card for desktop computers. It provides direct connection to Allen Bradley DH+ and Remote I/O networks through a standard PCI slot.

Installation Guide – Hardware Setup and Driver Configuration

The 1784-PCIC requires both hardware installation and driver configuration. Follow these steps for successful setup.

Hardware installation steps:

1. Power off the computer and unplug the power cord.
2. Remove the computer case cover.
3. Identify an available PCI slot. The card requires a 5V PCI slot.
4. Insert the card into the PCI slot firmly. Ensure the card is fully seated.
5. If using hardware configuration, set the jumpers on the card according to your system requirements.
6. If using software configuration, set the jumpers to software-configurable mode.
7. Secure the card with the bracket screw.
8. Close the case and reconnect the power.

Driver installation steps:

1. Power on the computer. Windows will detect new hardware.
2. Install RSLinx software (version 2.50 or later is recommended).
3. Open RSLinx. Go to Configure Drivers.
4. Select "AB_PCI-1" from the driver list.
5. Click "Add". The driver name will appear in the driver list.
6. Verify the card is recognized correctly in RSLinx.
7. If the card is not recognized, check IRQ and I/O address conflicts.

Common troubleshooting steps:

• If the card is not recognized, try a different PCI slot.
• Check that the PCI slot is a 5V slot (3.3V slots are not supported).
• Check IRQ conflicts in Windows Device Manager.
• Check I/O address conflicts in Windows Device Manager.

Jumper Settings – Hardware Configuration

The 1784-PCIC has jumper blocks on the card. These set the IRQ and I/O address for hardware configuration mode.

Jumper locations:

• Jumper JP1: Sets the I/O address base.
• Jumper JP2: Sets the IRQ line.
• Jumper JP3: Sets the configuration mode (hardware or software).

Software configuration mode:

• Set JP3 to software-configurable mode.
• The IRQ and I/O address are set through RSLinx software.
• This is the recommended mode for most users.

Hardware configuration mode:

• Set JP3 to hardware mode.
• Set JP1 for the I/O address base.
• Set JP2 for the IRQ line.
• Use this mode if the software configuration does not work.

Default settings (software mode):

• I/O address: Configured by RSLinx (typically 0x300 to 0x30F).
• IRQ: Configured by RSLinx (typically IRQ 5, 9, 10, or 11).
• DMA: Not used.

PCI Slot Compatibility – 5V vs 3.3V Slots

The 1784-PCIC is designed for 5V PCI slots. It does not work in 3.3V PCI slots. Check your computer's PCI slot type before ordering.

How to identify your PCI slot:

• 5V slot: The key notch is located at pin positions 50-51 (closer to the rear of the slot).
• 3.3V slot: The key notch is located at pin positions 12-13 (closer to the front of the slot).
• Universal slot: Two key notches at both positions. Accepts both 5V and 3.3V cards.

Field issue example: A customer inserted the 1784-PCIC into a 3.3V slot on a newer PC. The system did not recognize the card. Cause: Voltage mismatch. Fix: Moved the card to a 5V PCI slot. The card was recognized immediately.

Operating System Compatibility

The 1784-PCIC is designed for older Windows operating systems. Compatibility with newer Windows versions is limited.

Recommendation:

• Use a 32-bit version of Windows XP or Windows 7 for reliable operation.
• If using a 64-bit system, consider using a virtual machine with a 32-bit Windows XP.
• For newer systems, consider using the 1784-U2DHP (USB to DH+) adapter instead.

Status LEDs and Troubleshooting

The 1784-PCIC has LEDs on the rear bracket. These provide network status information.

Product Authenticity Verification

Allen Bradley 1784-PCIC cards are commonly counterfeited. Use these checks to verify authenticity.

• Card color: Genuine cards have a specific green color consistent with Allen Bradley PCI cards. Counterfeits often have a different shade or darker green.
• Label quality: Genuine labels have permanent printing with the model number 1784-PCIC clearly visible. Counterfeit labels often have blurry text or peel at edges.
• Jumper pins: Genuine cards have gold-plated jumper pins. Counterfeits often use tin pins.
• PCI connector: Genuine PCI connectors are gold-plated. Counterfeits often use tin connectors.
• Component quality: Genuine cards have high-quality capacitors and chips. Counterfeits often use low-cost components with uneven soldering.
• Weight: Genuine 1784-PCIC weighs approximately 0.1 kg. Counterfeits often feel lighter.

If the card is not recognized in RSLinx after correct installation, suspect a counterfeit. Contact Feimu Technology with photos for verification.
