5 Operation
5.1 Power and Communication
DWETH101 is powered via CPE. To power and communicate with the device it should be plugged into a CPE compatible
power source. The following diagram shows connection using a PoE compatible switch with
CPE100 powering a chain:
The DWETH101 may also be powered using a passive injector with a standard (non-PoE compliant) switch:
On connection the DWETH101 will source power from the upstream CPE device and become a CPE provider on the other
Ethernet port.
Once plugged in the DWETH will attempt to gather network parameters using the DHCP protocol. If successful it will
announce its presence to the CUWB network server on the subnet provided by DHCP. If the DWETH111 fails to connect to
the DHCP server it will fall back on auto-IP parameters and announce its presence using those parameters.
5.2 Configuration
Details regarding DWETH setup and configuration for the CUWB RTLS can be found on the CUWB Documentation Site .
5.3 Sensor Data Reporting
DWETH101 has a variety of sensors and can be configured to transmit data from those sensors. Sensor data received by
the CUWB server is broadcast via the
Ciholas Data Protocol (CDP) providing access to users.
