Page 12: Understanding Data Communication Configurations
Introduction Understanding Data Communication Configurations The 8410 WFT’s versatility allows the user to establish data communication links using a variety of configurations. This makes it possible to extend the range of the 8410 WFT and operate in a number of applications. This section describes the two main categories of communication configurations: Point-to-Point and Point-to-Multipoint. -
Page 13: Point-To-Multipoint Systems
Figure 1-6 depicts a standard point-to-multipoint system. In this example, any data sent from the master is broadcasted to all three slaves, one of which receives it through a multipoint repeater. The data is in turn sent out of the RS-232 or RS-485 port of each of the three slaves. 8410... -
Page 14: Choosing Point-To-Point Or Point-To-Multipoint Operation
However, if each slave will be transmitting data more frequently, the system will be closer to capacity and fewer slaves should be linked to the master. For examples and additional information on data communication links, please consult Varec, Inc. Installation and Operations Manual... -
