4.6 Positioning the Transmitters
The performance of radio signals are notoriously difficult to predict due to obstacles,
reflections, interference etc. If there are known issues such as for instance a steel
bulkhead care should be taken in positioning the transmitters and the base-station to
ensure satisfactory transmission signal strength. Positioning of the Base-station aerials
can also have a marked effect on performance see
Antenna Diversity
.
In general transmitter should be mounted so that the antenna is vertically orientated
and at least 1 metre above ground level. If a particular transmitter is not producing
sufficient field strength then it may benefit from an alternative directional aerial or re-
positioning. It is for these reasons that, in all but the most simple and straightforward
installations, we would recommend a site survey prior to determining the final
positioning of all the transmitters. Contact the sales office for details.

PC Software
5.1 General
For Hardware configuration:
spY-config must be installed on a PC used to setup the spYdaq base-station via USB.
The configuration internal to the base-station must match the transmitter switch
configuration. The user can also setup alarm for each transmitter which will activate
the internal relay and beeper. Customer using spYmonitor has the option to set soft
alarms. Soft alarms can also be set to send emails and/or sms on alarm.
5.2 Installing the spY-config software
Insert the USB drive into your computer and locate the installation exe file.

Modbus Masters
The spYdaq base-station has a MODBUS RTU output which is compatible with a wide
range of software platforms, PLCs etc.
We have worked with a number of SCADA systems, including Integraxor, Specview and
Prodigy, but many other systems are available. For more information contact the sales
office.
Modbus is not available on all Base-stations. If you require Modbus make sure that it was
specified on the order. If in doubt, contact our support team.
