DS3800NGRA1F1B | Mark IV General Purpose Remote Adapter Module

Description

Product Introduction

The DS3800NGRA1F1B is a premium version of the general-purpose remote adapter—the NGRA with extended temperature range, enhanced diagnostics, and conformal coating. The suffix tells the story: the first “1” indicates a hardware revision with improved signal conditioning. The “F” specifies extended temperature range components with higher-grade capacitors and oscillators. The second “1” adds enhanced diagnostic features (configuration verification, link quality monitoring). The final “B” is the conformal coating with humidity-resistant components. This board was designed for installations where the standard NGRA wasn’t sufficient—where extended temperature range, better diagnostics, and environmental protection were needed.

The conformal coating provides protection against humidity and dust. The extended temperature range means the board can operate in uninsulated shelters or outdoor cabinets. The enhanced diagnostics verify the board’s configuration and provide detailed status reporting. Compare this to the base DS3800NGRA (standard temperature range, no diagnostics, no coating). The 1F1B gives you the same basic functionality with significant improvements in reliability and diagnostic capability.

Frequently Asked Questions (FAQ)

What’s the difference between the NGRA1F1B and the base NGRA?
The 1F1B adds enhanced diagnostics (configuration verification, link quality monitoring), extended temperature range (-40°C to +70°C vs 0 to 60°C), and conformal coating. The base NGRA has basic link status only. The coating provides protection against humidity and dust.

What’s the “Config OK” LED?
The Config OK LED verifies that the board’s jumper and firmware settings are consistent with the Mark IV system’s configuration. If the LED is green, the configuration is correct. If it’s red, the board is misconfigured—check the jumper settings and the firmware configuration.

Do I need to upgrade my DMP firmware for the enhanced diagnostics?
The enhanced diagnostics require DMP firmware v3.0 or later. Older firmware won’t recognize the diagnostic registers. We can provide the firmware EPROMs if you need them.

What’s the conformal coating?
The acrylate-based conformal coating provides protection against humidity and dust. It’s the standard level of protection for most Mark IV boards. If you need UV protection or better humidity resistance, look for the “C” variant (dual-layer with UV topcoat) or the “D” variant (triple-layer military-grade).

How is the NGRA configured?
The NGRA is configured via jumpers on the board or through firmware settings. If you’re replacing a failed NGRA, photograph the jumper settings before removing the old board. The Config OK LED will verify that the settings are correct.

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 your warranty and lead time?
We stock the NGRA1F1B 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.
