Configured for dual-channel communication between a host computer and Allen-Bradley Data Highway Plus and Remote I/O networks, the Allen-Bradley 1784-PKTXD/A (1784-PKTXD) provides PCI bus-based network interface hardware.

Catalog Identification

The supplied catalog data identifies 1784-PKTXD as a computer interface card with a PCI bus interface and dual-channel Data Highway Plus and RIO network capability. The supplied spare references are 1784PKTXD and 1784-PKTXD/A. No further suffix decoding is assigned without manufacturer documentation.

Hardware Data

PCI and Network Interface Characteristics

The 1784-PKTXD provides a hardware interface between a PCI-based host computer and specified Allen-Bradley Data Highway Plus and Remote I/O networks. Its dual-channel configuration provides two network interface channels within the card architecture.

The supplied information does not define PCI electrical loading, bus-mastering behavior, interrupt configuration, network baud rate, maximum node count, or channel isolation. These values should therefore be taken from the applicable Allen-Bradley hardware manual rather than inferred from the catalog number.

Ordering Configuration

• 1 x Allen-Bradley 1784-PKTXD PCI Bus Computer Interface Card
• Catalog reference: 1784PKTXD
• Alternate reference: 1784-PKTXD/A
• 1 x interface card only unless additional accessories are explicitly specified
• Network cables, terminators, host computer hardware, and software are not identified in the supplied product data

Host Computer Installation

PCI Slot

• Install the card in a compatible PCI expansion slot.
• Confirm the host computer architecture and available PCI resources before installation.
• Secure the card mechanically to prevent movement during cable connection.

Network Connection

• Connect each network channel according to the applicable Data Highway Plus or RIO wiring requirements.
• Keep communication cabling separated from high-voltage and high-current conductors where practical.
• Maintain the specified network termination and shielding arrangement for the installed system.

Grounding and Shielding

• Follow the host computer grounding scheme and the Allen-Bradley network wiring specification.
• Avoid creating unintended shield-current paths between separately grounded equipment.
• Inspect connectors before energizing the host system.

Service Replacement

• Record the existing host configuration before replacing the interface card.
• Verify the installed communication software and driver requirements against the replacement hardware.
• Do not assume software compatibility solely from the 1784-PKTXD catalog number.

Technical FAQ

• What type of hardware is the 1784-PKTXD?

  It is a PCI bus computer interface card designed for communication with Allen-Bradley Data Highway Plus and Remote I/O networks.

• How many communication channels are provided?

  The supplied product information specifies a dual-channel configuration. The exact electrical behavior of each channel is not specified in the supplied data.

• What host interface does the card use?

  The listed host interface is PCI Bus. The supplied information does not specify PCI revision, bus width, interrupt mode, or electrical loading.

• Does the card support Data Highway Plus?

  Yes. Data Highway Plus is explicitly identified as a supported network type in the supplied product information.

• Does the card support Remote I/O?

  Yes. The supplied description identifies RIO, or Remote I/O, as a supported network interface function.

• Is hot swapping supported?

  Hot swapping is not confirmed by the supplied information. The host computer should be powered down before removing or installing the PCI card unless the complete system documentation states otherwise.

• What is the specified operating temperature?

  No operating temperature range is provided in the supplied data. Environmental limits should be verified against the applicable Allen-Bradley technical documentation.

• What is the specified power consumption?

  The supplied data does not provide a power consumption value. PCI slot power requirements should be verified before installation in the selected host computer.
