DS3800NGTA1E1D | Mark IV General Purpose Transceiver Adapter Module

Description

Product Introduction

The DS3800NGTA1E1D is a premium military-grade version of the general-purpose transceiver adapter—the NGTA built for installations where the highest level of reliability and environmental tolerance is required. The suffix tells the story: the first “1” indicates a hardware revision with improved signal conditioning. The “E” specifies military-grade components with higher-grade capacitors and oscillators. The second “1” adds enhanced diagnostic features. The final “D” is the environmental package: triple-layer conformal coating, hermetically sealed components, and MIL-STD-810G shock/vibration tolerance. This board was designed for installations where the standard NGTA would fail—offshore platforms, military installations, or critical infrastructure where transceiver connectivity reliability isn’t optional.

The triple-layer coating protects against humidity, salt spray, and corrosive gases. The MIL-STD-810G rating means it survives 75g shock and 8g vibration. Compare this to the NGTA1D1D (military-grade with standard components). The 1E1D has higher-grade capacitors and oscillators for extended reliability in the most demanding conditions.

Frequently Asked Questions (FAQ)

What’s the difference between the NGTA1E1D and the NGTA1D1D?
The “E” suffix indicates higher-grade capacitors and oscillators—rated for longer life at extreme temperatures. Both boards are military-grade with triple-layer coating and MIL-STD-810G certification. The “E” variant is for extended reliability in the most demanding conditions; the “D” variant is for standard military-grade applications.

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.

What’s the triple-layer coating?
The first layer is a standard acrylic conformal coating. The second layer is a silicone-based coating that adds flexibility and thermal shock resistance. The third layer is a urethane topcoat with UV protection—it’s harder and more abrasion-resistant. The combination protects against humidity, salt spray, corrosive gases, and mechanical abrasion.

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.

How is the NGTA configured?
The NGTA is configured via jumpers on the board or through firmware settings. If you’re replacing a failed NGTA, 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. The 1E1D has additional securing clips—make sure they’re properly engaged before powering up.

What’s your warranty and lead time?
We stock the NGTA1E1D in limited quantities. Lead time is 2-3 business days. We offer a 2-year warranty. We test every board with a 48-hour burn-in, a thermal cycle (-55°C to +85°C), and a full 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.
