- Consolidates two independently assigned Allen-Bradley network connections in one industrial computer
- Allows the host to perform separate engineering, data-exchange, or remote I/O duties through one installed card
- Keeps the two communication paths logically separate so each network retains its own operating role
1784-KTXD gives a compatible industrial computer two separately managed interfaces for communicating with supported Allen-Bradley controllers and I/O equipment.
The dual-channel arrangement is intended for host systems that must maintain two network paths without passing traffic directly from one channel to the other.
During replacement, preserve the relationship between each physical cable, host driver, and assigned network task, then prove both paths independently before returning the computer to operation.
Availability, condition, price, and shipping time for 1784-KTXD are confirmed during quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Channel 1 supports DH+, DH-485, or remote I/O scanner operation.
- Channel 2 supports DH+ or remote I/O scanner operation.
- The two channels do not bridge traffic from one network to the other.
- Install the card only in a compatible 16-bit ISA or EISA slot.
- Reserve independent base-memory and interrupt resources for the configured channels.
- Check BIOS shadowing and other installed adapters before assigning resources.
- Restore the saved mode, station address, baud rate, and driver for each channel.
- Confirm the correct connectors, cable polarity, and termination for both networks.
- Validate each channel independently with the documented diagnostic utility.
- Two independent DH+ communication paths in a compatible host computer.
- DH-485 communication on channel 1 with a separate DH+ or remote I/O channel.
- Dual-channel PC-based remote I/O scanner applications.
