A DWETH is an Ultra-Wideband (UWB) transceiver intended for use with the Ciholas UWB (CUWB) Real Time Location Systems (RTLS). In a typical CUWB RTLS the DWETH operates as a static, or anchored, device providing reference locations for the system. DWETH111 uses Ethernet to provide reliable, high-bandwidth data connectivity, and has a comprehensive set of on board sensors. DWETH111 anchors are Powered over Ethernet (PoE) and are PoE standard compliant.
DWETH111 devices are FCC certified in the United States, and have CE marking in the European Union.
Note: Not all hardware features are supported by CUWB System software. See CUWB.io documentation for specific feature support.

The DWETH111 is compliant with PoE 802.3af standards and can be plugged directly into PoE compliant Power Sourcing Equipment (PSE) devices to receive both power and communications. The DWETH111 will negotiate with the PSE as a class 1 device with a maximum allowable power draw of 3.84 Watts.
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.
Details regarding DWETH setup and configuration for the CUWB RTLS can be found on the CUWB Documentation Site.
DWETH111 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.
Sensor scaling and data rates can be configured for the following types of data:
|Sensor Type||Measurement Standard|
|3-Axis Accelerometer||standard gravity (g)|
The DWETH111 has tri-color (RGB) LEDs for conveying device state to users. In normal1 operation the device state can be determined using the table below:
|Network Status||Color||ON Time||Period|
|Power On Reset2||Blue||500mS||N/A|
The RGB LED also conveys error states to the user. An error is indicated by a 500mS red flash followed by a color sequence. The following color sequences are used to decode error states:
|Red — White-White-White||7||DW1000 communication error|
This indicates that the DWETH firmware is unable to communicate with the UWB transceiver. To clear this error reset the device by removing and reapplying power. If the problem persists please contact Ciholas for support.
