Each network configuration can have one master and up to 32 slave devices. Each controller is internally
configured to respond to a unique address. A master could be a protection switch, earth station
controller, or any micro- or mini-computer that is electrically and operationally compatible with RS-422.
Since the electrical specifications are very similar to EIA standards RS-422 and RS-449, virtually any
computer that meets these standards is capable of controlling remote devices.
Figure 2 and 3 show RS-422 Master and Slave connections respectively.
