The OMWT-AIN5V 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-AIN5V
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-AIN5V to
consume verylow 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-AIN5V
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
sensor 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 from the
manufacturer. Push and
hold the service switch for
10 seconds or more 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.a
