Features:
- One PCI card supports DH+, DH‑485, or Remote I/O (selectable), eliminating the need for separate cards.
- Automatic base memory address and interrupt request (IRQ) assignment for easy installation.
- On‑board LEDs per channel, included diagnostic software, and support for standard Allen‑Bradley cables
The 1784-PKTX/B replaces multiple single‑protocol interface cards with one PCI card. You can configure its single channel to operate on DH+, DH‑485, or Remote I/O networks without changing hardware. This is ideal for plants that have a mix of legacy Allen‑Bradley PLCs, such as SLC 5/04 (DH+), SLC family (DH‑485), or classic controllers on RIO.
The 1784-PKTX/B leverages local PCI bus technology to automatically assign base memory addresses and interrupt requests (IRQs). This eliminates manual jumper settings or software conflicts common with older ISA cards. When installed in a Windows 95 or Windows NT PC, the operating system detects the card and, together with RSLinx software, configures the communication parameters.
The 1784-PKTX/B includes on‑board LEDs (one per channel) that provide immediate visual status of network activity and card health. If a connection fails, technicians can quickly see if the card is powered, if the network is idle, or if a collision occurred. Additionally, the card comes with diagnostic software that performs comprehensive tests on the PCI interface, dual‑port memory, and host PC.
The 1784-PKTX/B Allen-Bradley Communication Card may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Legacy System Maintenance and Integration: Extends the lifespan of PLC-5 and SLC 500 systems by connecting modern PCs to legacy Data Highway Plus (DH+) or Remote I/O (RIO) networks.
- Industrial Control and Monitoring: Utilizes its I/O scanner function to support soft-control or embedded control engines for real-time data acquisition and equipment monitoring.
- PLC Programming and Configuration: Engineers can use this card to run RSLogix 5 or RSLogix 500 software on a PC to upload, download, and debug field controllers online.
- Multi-protocol Support: Single-channel selectable support for DH+, DH-485, or Universal Remote I/O (RIO), reducing spare parts storage types.
- DH+/RIO: Up to 230.4 kbps at a distance of approximately 762 meters (2,500 feet).
- PCI Compatibility: Universal card design conforming to the PCI 2.3 specification, supporting 3.3V or 5V signal environments, and can be inserted into 32-bit or 64-bit PCI slots (without using 64-bit expansion functionality).
- Less-Store Automation Upgrades: Integrate the legacy 1771 I/O framework into a modern PC-based automation architecture without replacing existing RIO cabling.
- Diagnostic and Maintenance Workstations: Portable or desktop maintenance stations utilize onboard LED diagnostic indicators to quickly diagnose network connectivity status and hardware faults.
- Technical Limitations:This card natively supports older operating systems such as Windows XP/7 (32-bit); while there is a compatibility record for Windows 10/11, specific driver support or a virtualization environment is usually required.
