INSTALLATION

Installation of the WMS-16 is simple and straight forward, thanks to its modular design and terminal-strip connections. Figure 1 shows the control module’s rear panel and the locations of the various connections. An auxiliary battery can be used as an alternative power input if you do not intend to use the provided wall transformer.

Installation Considerations

Prior to installing the WMS-16, you should be aware of several important points that must be taken into consideration when choosing a site for the control module and sensors.

Control Module

The control module should be located as close as possible to the computer that will be used to communicate with the WMS-16. RS-232 communications (the communication protocol used with the WMS-16) is designed for use over short distances, and the cable connecting the control module to the computer should not be longer than 30 feet (10 meters). Longer lengths may work.

If this arrangement is not feasible and a longer cable run is required, an RS-232 to RS-422 converter can be added to allow longer cable runs.

Barometric Pressure Module

The Barometric Pressure Module is designed to be mounted indoors. This arrangement assumes that the barometric pressure indoors and outdoors is equal. The Barometric Pressure Module is provided with a short cable that connects directly to the control module.
