There are a growing number of remote
communications applications where power consumption is a major issue. Often,
these environments are solar powered and require that equipment operate over a
wide voltage range. The StarComm 1442L and 33421L are designed to address
these specific requirements.
Since all StarComm communications products are designed to withstand the
rigors of industrial use, you can expect years of trouble free operation from
the 1442L and 3342L. From traffic monitoring applications, in the heat of the
Arizona desert to weather surveillance installations in Alaska, StarComm. has
developed a reputation for performance, quality and unique feature sets:
AUTOMATIC POWER UP ON RING DETECT - StarComm Low Power
Modems remain in a low power standby mode until an incoming call presents a
ring signal to the device. When the ring signals detected the device powers on
and accepts the call. After the call has completed, the device will return to
a low power standby mode.
EXTERNAL POWER SEQUENCING ON RING DETECT - All models
provide relay contacts for sequencing power to other devices. The relay is
activated after the first ring cycle and deactivated when the modem returns to
low power standby mode.
FLEXIBLE POWER SUPPLY OPTIONS - All models offer power
options to meet a wide range of AC and DC requirements.
F
LEXIBLE PACKAGE OPTIONS - All models are
available in our standard stand alone or rack mount configurations. In
addition, all models are available at the board level for OEM applications.
