74 RC2000C Polar Tracking Antenna Controller Appendix E Communications Protocol
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.
