Product Introduction
The DS3800NLIA is a local interface adapter board for Mark IV systems—the “L” in the suffix indicates local, the “I” indicates interface, and the “A” is a manufacturing revision. This board provides local interface connectivity and signal distribution within the Mark IV rack and to adjacent equipment. It was used in installations where local interface signals needed to be distributed between boards or to external equipment.
The board plugs into the Mark IV backplane and provides a local interface. Compare this to the DS3800NLBA (local bus adapter) or the DS3800NLCA (local communications adapter). The NLIA is specifically for local interface applications where signal distribution within the rack is needed.

Frequently Asked Questions (FAQ)
What does the NLIA board do?
The NLIA is a local interface adapter board for Mark IV systems. It provides local interface connectivity and signal distribution within the Mark IV rack and to adjacent equipment.
What’s the difference between the NLIA and the NLBA?
The NLIA is for local interface signal distribution. The NLBA is for local bus signal distribution. The NLIA handles interface signals; the NLBA handles bus signals. Check your system documentation for the specific application.
Can I hot-swap this board?
No. Mark IV backplanes are not hot-swappable. Power down the cabinet, lock out the breaker, and wait 60 seconds before removing or installing the board.
What’s the most common failure mode on the NLIA?
We’ve serviced about a dozen NLIA boards. The most common failure is the interface circuitry—it can degrade over time, causing signal integrity issues. The second most common failure is the edge connector—corrosion from humidity. The board is repairable.
What’s your warranty and lead time?
We stock the NLIA in limited quantities. Lead time is 1-2 business days. We offer a 1-year warranty. We test every board with a 24-hour burn-in and a diagnostic verification. The test report is included.
Is this board compatible with the Mark VIe?
No. This board is for Mark IV systems only. The backplane architecture is different.
