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.
