Manufacturer

The Ndigo5G is a product of:

cronologic GmbH & Co. KG

Jahnstraße 49

60318 Frankfurt

HRA 42869 beim Amtsgericht Frankfurt/M

VAT-ID: DE235184378

Intended Use and System Integration

The devices are not ready to use as delivered by cronologic. It requires the development of specialized software to fulfill the application of the end user. The device is provided to system integrators to be built into measurement systems that are distributed to end users. These systems usually consist of a Ndigo5G, a main board, a case, application software and possible additional electronics to attach the system to some type of detector. They might also be integrated with the detector.

The Ndigo5G is designed to comply with DIN EN 61326-1 when operated on a PCIe compliant main board housed in a properly shielded enclosure. When operated in a closed standard compliant PC enclosure the device does not pose any hazards as defined by EN 61010-1.

Radiated emissions, noise immunity and safety highly depend on the quality of the enclosure. It is the responsibility of the system integrator to ensure that the assembled system is compliant to applicable standards of the country that the system is operated in, especially regarding user safety and electromagnetic interference. Compliance was only tested for attached cables shorter than 3 m.

When handling the board, adequate measures have to be taken to protect the circuits against electrostatic discharge (ESD). All power supplied to the system must be turned off before installing the board.

Cooling

The Ndigo5G in its base configuration has passive cooling that requires a certain amount of air flow. If the case design cannot provide enough air flow to the board, a slot cooler like the Zalman ZM-SC100 can be placed next to the board. Active cooling is also available as an option to the board.

Environmental Conditions

See Environmental Conditions for Operation and Environmental Conditions for Storage.

Inputs

All inputs are AC coupled. The inputs have very high input bandwidth requirements and therefore there are no circuits that provide over-voltage protection for these signals. Any voltage on the inputs above 5 V or below –5 V relative to the voltage of the slot cover can result in permanent damage to the board.

Erratum

Thunderbolt

The Ndigo5G does not work in most Thunderbolt PCIe extension enclosures. The reason is unknown.

Workarounds:

• Use the Ndigo6G. All other cronologic products work reliably in Thunderbolt enclosures. The Ndigo6G offers very similar functionality to the Ndigo5G at a higher performance.¹

PCIe 5.0

The Ndigo5G might not work in PCIe 5.0 slots that support the “Enhanced Link Behavior Control” feature.

Workarounds:

• Disable “Enhanced Link Behavior Control” in BIOS.

• Limit PCIe transfer rates to transfer rates of up to PCIe 4.

• If your main board has PCIe slots that are not PCIe 5.0, install your Ndigo5G in these.

• Use Ndigo6G. The Ndigo6G works reliably in PCIe 5.0 slots while offering similar functionality.¹

¹ When using the Ndigo6G as a replacement, there are some software changes required in the device configuration. The readout data format and API is largely identical. See www.cronologic.de/products/adcs/ndigo6g-12 for details.

PCIe Connector

Some electrical components on the Ndigo5G-10 and Ndigo5G-S-C boards are placed close to the PCIe connector, and thus may, in rare cases, get shorted by metal shielding elements of the PCIe slot of the mainboard. This will neither damage the Ndigo5G board nor the mainboard, however, the shortened PCIe lanes will not be functional.

Make sure to follow the installation instructions in Installing the Board.

Recycling

cronologic is registered with the “Stiftung Elektro-Altgeräte Register” as a manufacturer of electronic systems with Registration ID DE 77895909.

The Ndigo5G belongs to category 9, “Überwachungs und Kontrollinstrumente für ausschließlich gewerbliche Nutzung.” The last owner of an Ndigo5G must recycle it, treat the board in compliance with §11 and §12 of the German ElektroG, or return it to the manufacturer’s address listed above.

Export Control

The Ndigo5G product line is a dual use item under Council Regulation (EC) No 428/2009 of 5 May 2009 in section 3A002h. Similar regulations exist in many countries outside Europe.

Regardless of the fact that we at cronologic exclude the use of our products for military purposes, the laws of the EU and many other countries restrict exports of dual-use items. Since we have to apply for a General Export Permit for these countries, delivery processes may be delayed or delivery to certain countries may become impossible.

For the application of this export license, we need the following documents from you:

• Exporter declaration

• Company profile

• Import license (country dependent)

There are countries for which a General Export License can be used for the export of dual-use goods. In this case we need the corresponding documents from you and there will be no further delay. These include:

• Australia

• Japan

• Canada

• Liechtenstein

• New Zealand

• Norway

• Switzerland

• Singapore

• USA

Before re-exporting an Ndigo5G or any product containing an Ndigo5G as a component, please check you local regulations whether an export permit is required.

It is not permitted to export an Ndigo5G to the Russian Federation or the Republic of Belarus.
