R&S®SA129 Station Monitoring Unit
Monitoring of remote stations
The Station Monitoring Unit R&S® SA129 provides extensive capabilities for the supervision of remote stations.
A station monitoring system consists of one R&S® SA129 (which functions as a status display and remote control console) in the control station and one R&S® SA129 per remote station.
The R&S® SA129 in the remote station scans the connected sensors and executes the remote control commands received from the R&S® SA129 in the control station. Various sensors are available for monitoring the opening of windows or doors, temperature, relative humidity, smoke detection and power supply, for example. If an R&S® SA129 detects a change in the status of one of the sensors, it sends a message to the R&S® SA129 in the control station, where the status is displayed on the LCD display. In addition, the status can be output on a printer and/or a visual and/or acoustic signal can be set.
Another application of the R&S® SA129 involves reinitializing a remote system by interrupting the power supply, the system process controller being shut down beforehand via a UPS to prevent data loss.
The Station Monitoring Unit R&S® SA129 comes in two versions:
- R&S® SA129 for communication via dialed PSTN lines, and
- R&S® SA129C and R&S® SA129R for communication via LAN
Note: For easier reading throughout this web site we refer to both models as R&S® SA129. Features unique for the R&S® SA129C/R are explicitly mentioned. Information regarding specific means of communication always refer to the corresponding model only.
