Description

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. DWETH101 uses Ethernet to provide reliable, high-bandwidth data connectivity, and has a comprehensive set of on board sensors. DWETH101 anchors contain a built-in Ethernet switch and support Chainable Powered Ethernet (CPE), allowing for a chain of devices to be powered via a single source.

DWETH101 devices are FCC certified in the United States, and have CE marking in the European Union.

Operation

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.

Configuration

Details regarding DWETH setup and configuration for the CUWB RTLS can be found on the CUWB Documentation Site.

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.

Sensor scaling and data rates can be configured for the following types of data:

Sensor Type Measurement Standard
3-Axis Accelerometer standard gravity (g)
3-Axis Gyroscope °/Second
3-Axis Magnetometer µTesla
Absolute Pressure hPascal
Temperature °C
Quaternions Unit Coefficients

LED Indication

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
ON Network Green 10mS 1.0S
OFF Network Green 10mS 10.0S
Power On Reset2 Blue 500mS N/A
  1. This table denotes normal LED operation. The CUWB network can be configured to show different patterns on the LEDs
  2. Power On Reset (POR) occurs only on system reset. This will happen when charging a dead battery, on reboot after firmware update, and when the device resets due to system watchdog.

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:

Color Sequence Code Description
Red — White-White-White 7 DW1000 communication error

Error Handling

[CODE 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.
