7.4.1 Modes of Configuration
Point-to-point is a simple configuration in which two devices located at two different places are
interfaces to communicate with each other by using cable, modem etc. Simple point-to-point
configuration between Dynamet 5 and COM1 on PC is shown in figure below. Cable interface in
this figure can be replaced with RF or serial interface converter.
Point-to-multi-point configuration is one in which two or more devices located at different places
are interfaced to communicate with single control station or PC. An example of point-to-multi-
point configuration is shown in figure below. Data loggers Logger 0, Logger 1 and Logger 2 are
setup to communicate with PC on COM1. Logger Net can program host modem to communicate
with only one of the remote stations at any given time.
