1819 可编程调制解调器

电子工业是一个不断发展的有机体。
为了及时了解情况，设计人员必须习惯性地阅读并观看有关新产品功能和技术的最新消息。
许多工程师参加贸易展，作为学习过程的一部分。
我们的新产品发现视频系列将其带入了一个新时代，您将无需离开舒适的家或办公室即可了解新产品。
然而，这一次，我将向您展示我尚未了解的两种产品，希望它能激发并告知您，甚至可能激发您对新项目的想法。
我想告诉你Comair Rotron的现场可编程风扇和Digi International的XBee RF调制解调器。
Comair Rotron的Patriot和Major系列可编程风扇使客户能够对风扇进行现场编程，以适应特定应用，过去可能需要拆除和更换旧风扇，并希望替代风扇适合工作。
除了能够监控温度和流量等变量之外，这些可编程风扇还允许您将风扇设置为以您需要的任何参数运行，这意味着您可以在许多不同的应用中使用一种类型的风扇。
这些风扇的另一个好处是取消了“风扇控制器”。这些单元可以组合在一起，一个风扇充当主设备，其他风扇充当从设备。
总而言之，这些风扇降低了系统成本，设计时间和库存，并简化了整个供应链。
吸引我眼球的第二款产品是Digi International的XBee路由器。
现在，关于这个项目的一个重要注意事项是，为了使它运行，你需要在你正在与之通信的每一端（至少两个）有一个。
使用三个或更多单元，您可以设置Mesh网络;
否则它们可以用作点对点路由器。
这些路由器的优势在于它们能够传输的距离。
通过900 MHz ISM频段的跳频，它们能够在室内11英里和室外65英里（视距）的距离内传输高达1 W的功率。
这种功能使这些光滑的小型路由器适用于大型网络应用。
这些产品的典型应用是数字标牌，其中电缆昂贵且不切实际。
谢谢你的收看！

The electronics industry is a constantly evolving organism. To stay informed, designers have to habitually read and watch for the latest news on new product features and technology. Many engineers attend tradeshows as part of the learning process. Our New Product Discovery video series takes that to a new era where you get introduced to new products without having to leave the comfort of your home or office.
This time, however, I am going to show you two products that I had not yet known about, in hopes that it will excite and inform you and perhaps even inspire an idea for a new project. I want to tell you about a field programmable fan from Comair Rotron and an XBee RF Modem from Digi International.
The Patriot and Major series of programmable fans from Comair Rotron enable a customer to field program a fan to fit a specific application that, in the past, may have required removing and replacing the old fan and hoping the substitute fan fits the job. On top of being able to monitor variables like temperature and flow rate, these programmable fans allow you to set the fan to operate in whatever parameters you require, meaning you have the ability to use one type of fan in many different applications. One more bonus to these fans is the elimination of a “fan controller.” The units can be ganged together with one fan acting as the master and the others as slaves. All in all, these fans reduce system cost, design time, and inventory, and they simplify the overall supply chain.
The second product that caught my eye is an XBee router from Digi International. Now, an important note on this item is that, in order for it to operate, you are required to have one at each end (at least two) of what you are communicating with. With three or more units, you have the ability to set up a Mesh network; otherwise they can be used as just point to point routers. The advantage of these routers lies in the distances they are capable of transmitting. By frequency hopping in the 900 MHz ISM band, they are able to transmit up to 1 W of power at distances of 11 miles indoors and 65 miles outdoors (line-of-sight). This capability makes these slick little routers suited for huge networking applications. Typical applications of these products are in digital signage where a cable would be costly and impractical.
Thank you for watching!
