The OMWT-AIN10V Wireless
Voltage Transmitter is a battery
operated 12-bit analog-to-digital
converter with a microprocessor
controlled 418 MHz FCC certified
radio transmitter. The OMWT-AIN10V
has an on board time of day clock
that allows it to spend most of the
time in a low power quiescent state.
At predetermined time intervals the
clock will wake up the onboard
microprocessor. Unique serial
number information is read from a
semiconductor digital device and
analog data is read from a 12-bit
analog to digital converter. This
information is combined with a
CRC-16 error check and transmitted
in a very short data packet that
results in a transmitter on time of only
15 milliseconds. This architecture
allows the OMWT-AIN10V to
consume very low energy resulting
in a battery life of up to 2 years.
The electronics are coated with a
conformal rubber material that
provides a moisture barrier against
condensation. Submersion in water
is not recommended. A hole in the
top ABS cover permits a special tool
to be inserted to activate the service
switch. The OMWT-AIN10V is
shipped with the transmitter turned
off (anytime the device is to be
shipped the transmitter should
be turned off or must be placed
in a shielded container to prevent
interference that might cause
shipping problems).
Start the device by momentarily
pushing the service switch (you
will feel the button click). When the
service switch is pushed a data
transmission occurs immediately
and a special mark is
introduced in the ID field
of the transmitted data
packet to indicate
which device is in
service or
installation. The
service switch is also
used to put the device
in a quiescent mode
(no transmissions
and very low power
consumption). This is
the state the device is in
when you receive it.
Push and hold the
service switch for 10
seconds or ore to enter
this powered down state.
Using the OMWT Series Windows
software incoming data being received
from OMWT Series Wireless
Transmitters can be viewed in a
real-time or historical time-base
chart or numerical view. High/low
alarms can also be set for each
transmitter signal with either a visual
or audible alarm indication on the
PC. Data can also be logged to disk
at a user-specified rate in a text file
format that can be opened up into
Microsoft Excel. The OMWT Series
Windows software also includes a
DDE Server that can interface the
data being received from OMWT
Series Wireless Transmitters to
other Windows software packages.
