ANC-120e USB to DH+ PLC Programming Cable
The Premier USB to Data Highway Plus (DH+) Programming Cable
The Automation Networks ANC-120e is the industry-standard, cost-effective alternative to legacy Allen-Bradley 1784-U2DHP, 1784-PKTX, 1784-KTX, and 1784-PCMK interfaces. Designed for seamless connectivity between modern PCs and legacy DH+ networks, it allows you to program, monitor, and gather data from PLC-5 and SLC 5/04 controllers without downtime.
Key Technical Advantages:
-
Superior 1784-U2DHP Alternative: Compact, high-speed USB interface replacing obsolete PCMCIA and PCI cards.
-
Streamlined RSLINX & Windows Setup: Requires a simple, lightweight Windows USB driver (available for instant download below) and connects seamlessly using the standard “Remote Devices via Linx Gateway” driver in RSLINX—eliminating the need for complex, proprietary routing software.
-
Intelligent Auto-Detection: Automatically detects default baud rates (up to 230.4 kbps) and auto-polarity on the DH+ network.
-
Broad Compatibility: Works flawlessly with major HMI, SCADA, and PLC programming software packages.
✅ Fully Compatible with Windows 10 & Windows 11 (32-bit & 64-bit USB drivers available for instant download below)

Frequently Asked Questions (FAQ)
Q1: Will the ANC-120e work with my 64-bit Windows 10 or Windows 11 laptop?
A: Yes. The ANC-120e includes native, lightweight USB drivers fully compatible with both 32-bit and
64-bit versions of Windows 10 and Windows 11. It eliminates the system crashes
and OS incompatibility issues common when trying to run legacy PCMCIA or older
USB adapters on modern field laptops.
Q2: How does the ANC-120e integrate with RSLINX? Do I need complex Rockwell routing
software?
A: No proprietary routing software is required. Once the Windows USB driver is
installed, the ANC-120e communicates seamlessly using the standard “Remote
Devices via Linx Gateway” driver within RSLINX. This straightforward setup
allows your programming software (such as RSLogix 5 or RSLogix 500) to easily
browse and connect to the Data Highway Plus (DH+) network.
Q3: What Allen-Bradley PLC models and network baud rates are supported?
A: The adapter supports direct communication with all legacy Allen-Bradley PLC-5 and SLC 5/04
controllers on DH+ networks. It features intelligent auto-detection that
automatically adjusts to standard network baud rates, including 57.6 kbps,
115.2 kbps, and 230.4 kbps, without requiring manual DIP switch changes.
Q4: Is the ANC-120e compatible with third-party HMI and SCADA platforms like Ignition
or Wonderware?
A: Absolutely. Beyond Rockwell’s FactoryTalk and RSLogix suites, the ANC-120e
operates flawlessly with all major third-party industrial automation and SCADA
platforms, including Inductive Automation (Ignition), Wonderware, Kepware,
Citect, and TopServer.
Q5: Why choose the ANC-120e over an Allen-Bradley 1784-U2DHP?
A: Because original 1784-U2DHP interfaces are no longer manufactured by Rockwell Automation,
sourcing them today relies entirely on the third-party surplus and refurbished
market. This drives prices over $3,000 for aging hardware that typically comes
without a factory warranty or official technical support. The ANC-120e provides
a superior, brand-new alternative at $995, backed by full technical
support, immediate manufacturer stock, and reliable compatibility with modern
operating systems.
