예식일 : So are Termination Resistors Required?
문의내용:

May be filling the vast types of liquid filling, including high viscosity liquids. Such as: pharmaceuticals, chemicals, oils, cosmetics, food and other non-granulated liquid; filling with high precision, suitable for laboratory use. With support for open embedded platform and use the new version of the Linux kernel can package applications as well as the process of cross-compilation is much easier for new projects. Good documentation and examples of simple applications intelligent Installation to start. A simple intelligente installatie installation thanks to the removable screw terminals. Thanks to paperless chart recording technology; students and teachers are now able to clearly and conveniently visualize their experimental data. Users now have the ability to monitor their live data and store all the information on the Brainchild itself or on a connected PC. Additionally, the Brainchild's standard Ethernet and optional RS-232/RS-422/RS485 communication enable users to access data onsite from a remote location via the RS serial interface or Ethernet networking. The POE version makes this a single cable connection that will allow monitoring from anywhere in the world; anywhere with internet access that is.

NPE-series devices is an innovative and powerful platform for modern systems and remote monitoring. Its use of differential signaling makes it resistant to noise, and its support for up to 32 devices on a single network makes it suitable for a wide range of applications. Different Unit Loads in transceivers allow more devices on a network, including full, half, quarter, or eighth-unit load circuits. Students view the collected data in the display format or choose additional formats including vertical trend, horizontal trend, bar graph, and numerical. Users can browse through the alarm list or acknowledge alarms easily via function keys on the vertical bar. Multiple function keys make navigation a snap and also allow users to quickly scroll backward to review historical trends. Watch Dog function ensuring the control of selected applications in equipment. Software features include storing of maximum peak/minimum peak/peak-to-peak values, "Totalizer" function typical for flow control and "Sum" function for weighing systems.

The Brainchild also features digital I/O and Ethernet, removable flash memory data storage, and a plug & play I/O card. CAS DataLoggers together with high-quality manufacturer Brainchild has the solution with the VR-18 Paperless Chart Recorder, a high resolution (true VGA, 640x480 pixels) 18-channel data logger featuring an infrared detector, plug & play I/O card, high flexibility, and user-friendly operation, all in a compact size. Using the recorder's benchtop/portable configurations and panel mount, the VR-18 is an effective stand-alone solution to monitor, record, and evaluate processes in the laboratory, classroom or out in the field. One other key advantage that most people using 485 is, the better noise immunity. Innovation Helps you better development, win more market. When a "bad message" shows up on the cable, it is more difficult (but not impossible) to figure out which node(s) transmitted that message when you have a shared-medium with a dozen nodes connected to the same single cable, compared to a point-to-point medium with only 2 nodes connected to any particular cable. The higher the data rate and the longer the cable, the more likely it will be that you have to add termination resistors.

Since the RS-485 driver is "made passive" (disconnected from the wires) when not transmitting, and the other end of the cable can then drive the network, a termination resistor should be added to both ends. Sadly neither of these limits are in the RS-485 standard. RS-485 is a balanced data transmission standard for serial communication. Functionality of the data logger (Log) archival data taken with the possibility of their sharing as a file, database or transmission of data in external systems (eg SCADA). The presentation of Web pages (Web SCADA) directly from the device to visualize the current and historical data and remote control. Software updates remotely. Possible upgrade to the platform and innovative iMod NX Dynamics web modules. Update software remotely. Be updated in NX platform iMod and Dynamics modules. Functionality of the protocol converter (Convert) - collection of data coming from input interfaces, Ethernet, then the conversion and transmission on the GPRS or output interfaces to external modules.
