DS3800NGDC1A1A | OEM GE Speedtronic Fiber Optic I/O

Description

Product Introduction

The DS3800NGDC1A1A is an enhanced version of the general-purpose fiber optic board—the NGDC with improved diagnostics and component selection. The suffix tells the story: the first “1” indicates a hardware revision with improved signal conditioning and expanded configuration options. The “A” specifies the standard fiber optic interface. The second “1” adds enhanced diagnostic features (link quality monitoring, configuration verification). The final “A” is the standard environmental package (no conformal coating). This board was designed for installations where the standard NGDC wasn’t sufficient—where better diagnostics or more configuration options were needed.

The enhanced diagnostics verify the board’s configuration and provide detailed status reporting on the fiber link. Compare this to the base DS3800NGDC (general-purpose board, basic diagnostics). The 1A1A gives you the same basic functionality with better diagnostic feedback.

Frequently Asked Questions (FAQ)

What’s the difference between the NGDC1A1A and the base NGDC?
The 1A1A adds enhanced diagnostics—link quality monitoring, configuration verification, and error logging. The base NGDC has basic link status only. The configuration verification is useful—it checks that the jumpers and firmware settings are correct and that the board is properly configured for the application. If the Configuration OK LED is red, something is misconfigured.

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. This is a useful diagnostic feature—it catches misconfigurations before they cause problems.

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—the board will still pass data, but the Config OK LED won’t function correctly. We can provide the firmware EPROMs if you need them.

How is the NGDC configured?
The NGDC is configured via jumpers on the board or through firmware settings. The exact configuration depends on the application. Check your system documentation for the specific configuration requirements. If you’re replacing a failed NGDC, photograph the jumper settings before removing the old board. The Config OK LED will verify that the settings are correct.

Can I use this board with the long-haul fiber boards?
The NGDC1A1A was designed for the standard Mark IV fiber system. It may not be compatible with long-haul boards that use different wavelengths. Check your system configuration before mixing board types.

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 NGDC1A1A 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.
