SmarTek Systems Cabinet Interfaces
Sensing and Systems Integration Solutions
USI RPU
The SmarTek Systems Universal Sensor Interface (USI) is a low cost and
rugged programmable processor used as a custom interface between
various remote sensors or systems (traffic sensors, traffic counters,
weather stations, temperature and pavement sensors, etc.). The USI can
also be used as a low cost stand alone cabinet RPU.
The USI requires little power and has a very small foot print. The USI
includes a Maxim "One Wire" Micro-Lan Interface and hence, may be used
as a flexible custom interface for variety of devices that don't have an
RS-232 interface (relays, switches, temperature probes, etc.).

BL-2030
The SmarTek Systems, Inc. STS-BL2030 is a low cost and rugged
programmable processor used as a custom interface between various remote
sensors (loop detectors, traffic, weather, temperature, etc.) and a
standardized Remote Processing Unit (RPU) or for use as a stand alone RPU.
The STS-BL2030 requires little power and has a very small foot print. The
STS-BL2030 may also be used as a flexible custom interface for loop
detectors and other devices without a serial data stream.
