STAR® Submetering Data Collection Units
The Hexagram STAR® system provides fully automatic meter
reading without meter readers, handhelds, or expensive
wiring. Powerful, narrow band meter transmitters allow the
use of a single data collector, without repeaters, to
economically read large submetering installations in
developments, high-rises, and other multi-tenant communities.
- The STAR® Data Collection Unit (DCU) receives, timestamps,
and stores meter reading data collected from
STAR® Meter Transmission Units (MTUs).
- The STAR® DCU transfers meter reading information to
the STAR® Network Control Computer (NCC) installed at
any off-site location.
The STAR® DCU is mounted in a convenient
location such as a utility closet or storage
room. The DCU contains a radio receiver,
computer, and a modem. Power is provided
by a 120 vac source.
STAR ® MTU messages are received by the
DCU which decodes and error-checks the
data. The information is time-stamped,
processed, and stored with diagnostic
information and data from other MTUs.
Once each day, the DCU contacts the off-site NCC and transfers the
meter reading data. The NCC processes this information and provides
billing and customer service data.
The standard model DCU has a telephone modem for communication
with the NCC. However, the DCU can also be equipped with a cellular
modem or other communication device.
