The reason for this is that every data feed is on its own circuit. You can check terminals, and check all the connections individually.
For example, if you find position data is no longer feeding to one of your devices, but it is OK for everything else, you know the problem is with the listening connection between the device and the bus. On an NMEA system, it is much harder to find the fault. There will be very little indication of exactly which part of the network or which wire has the fault.
In our example above, if something stops receiving positional data it probably means the receiving instrument is faulty. If everything stopped receiving positional data, it would just indicate a fault somewhere within the network. You would have to undertake investigations to narrow it down further. Theoretically, it is simpler to find faults with NMEA equipment.
At the same time, however, it is easier for faults to creep in due to the nature of all the connections. NMEA is the current standard for inter-connecting marine electronic equipment on vessels. In the future, the standard will evolve and OneNet will take over. OneNet operates on similar principles to NMEA , with the main difference being that the connections are via ethernet instead.
This gives OneNet significantly higher bandwidth and faster data transfer speeds. Using ethernet connections allows more devices to be connected and generally permits the networks to become more complex. As we move towards the Internet of Things, this flexibility becomes even more important.
The increase in data transfer speeds and higher bandwidth means that more devices will be able to be connected. Examples include radar feeds and onboard CCTV. The data transfer required is too high for the current NMEA , but easily manageable by ethernet. Ethernet connections are already common around the world, in use in homes, offices and a whole range of other places.
The only thing holding it back from becoming commonplace in marine equipment is the need to have everything standardised across all manufacturers. The 'Delivers' timeframe is an estimate of when the item will be delivered to your shipping address after it ships. The estimated delivery time depends on the shipping method you choose during checkout. All estimates are based on business days. Remember that these estimates are for time in transit only, and that they do not apply until the product leaves the Fondriest warehouse.
As the delivery of your order is beyond Fondriest's control once your order leaves the Fondriest warehouse, we cannot assume liability for late deliveries, regardless of the delivery method you specify.
Most of Fondriest's shipments contain valuable equipment. If you will not be at the shipping address to accept delivery of your product, consider shipping the item to an address where someone you trust will be available to sign for your package, or accept your package if a signature is not required for the delivery.
Once your order has prepared for shipment or has shipped, we are unable to change the shipping address. Title and risk of loss to all products will pass to you on delivery. If you are willing to assume the risks of delivering your order without a signature, you may authorize Fondriest to arrange for a delivery that does not require anyone to be at the delivery address.
Occasionally packages are returned to Fondriest as undeliverable. When the carrier returns an undeliverable package to Fondriest, please contact us to make arrangements for reshipment. Most of Fondriest carriers make three attempts to deliver a package. After three delivery attempts, the carrier will return the package to Fondriest. The estimated shipment date on your order is based on product availability, payment processing time, and warehouse processing time and does not include transit time.
We do not begin payment processing until Fondriest receives all of the information that is needed and full payment or a full authorization, in the case of credit card or rental orders. Fondriest will begin payment processing for orders placed on weekends or holidays on the next business day.
Business days are Monday through Friday, excluding federal holidays. Your order for in-stock items that are eligible for same-day shipping must be received before your local time of p. Fondriest makes every effort to ship your product according to the estimated lead times.
The estimated lead times are in business days Monday through Friday, excluding federal holidays. Although Fondriest makes every effort to ship your order according to the lead time provided, shipping dates may change due to changes in supply.
If the lead time changes, Fondriest will contact you via email and provide a revised shipping estimate. Fondriest makes every effort to supply the products you order, but there may be occasions when Fondriest confirms orders and later learns that it cannot supply the products, either at all or in the quantities ordered.
Although rare, these occasions can include when Fondriest learns that the products no longer are being manufactured or they otherwise become unavailable, when Fondriest cannot source components for the configuration you ordered, or when there was a pricing error at the Fondriest Online Store.
In those circumstances, Fondriest will inform you and, if you are interested, Fondriest may suggest alternative products that may meet your needs. If you do not wish to order alternative products, Fondriest will cancel your order for products that cannot be supplied and for any other products that you no longer wish to order as a result, and will refund your purchase price.
If you are not satisfied with your purchase from Fondriest Environmental, you have up to 14 calendar days from the time you receive your item s to initiate a return.
Please request a Return Material Authorization RMA by contacting your account representative or the general customer support address: customercare fondriest.
