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 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-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 thetransmitted 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. 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.
Tranmission Distances Up to 20 Miles with Optional Repeater and Transceiver
The OMWT-REP-900 Wireless Repeater is a 418 MHz RF receiver with an integrated 900 MHz RF
transceiver. It receives data packets from all OMWT Series 418 MHz Wireless Transmitters within its range,
and then transmits the data via the built-in 900 MHz radio to an
OMWT-XREC-SER-900. Data received by the OMWT-XREC-SER-900 receiver with serial interface can be displayed and
logged using the OMWT-SOFT Windows Software.
* Indoors(with 1/2 wave antenna, conditions allowing) up to 1500ft
Outdoors(with Dipole antenna, conditions allowing) up to 7 mi
Outdoors(with Yagi antenna, conditions allowing) up to 20 mi
