A DWTAG is an Ultra-Wideband (UWB) transceiver intended for use with Ciholas UWB (CUWB) Real Time Location Systems (RTLS). In a typical CUWB RTLS system the DWTAG operates as a mobile device whose location is tracked. DWTAGs have a comprehensive set of on-board sensors and an integrated rechargeable battery. The DWTAG is lightweight with a mechanical design that allows for easy mounting on assets or personnel.
DWTAG 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 DWTAG is designed with a Micro USB Type-B connector for easy connection. To charge the battery connect to power via the Micro-USB connector. A device that is charging will drop off of any CUWB network that it is currently participating in.
DWTAG100 devices may also be charged using the Ciholas CHG100 charging rack.
The design of the DWTAG includes a USB to serial converter and may be connected to a USB compatible hub for communications.
The DWTAG will attempt to join any network that is within range of its UWB transceiver. If no network is in range the device will go into a low power mode periodically waking to check for presence of a CUWB network.
DWTAG devices must be added to the CUWB RTLS network configuration in order to join a network and beacon.
Details regarding DWTAG100 setup and configuration for the CUWB RTLS can be found on the CUWB Documentation Site.
DWTAG100 has a variety of sensors and can be configured to transmit data from those sensors. Sensor data received by the CUWB server 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 DWTAG100 has a tri-color (RGB) LED for conveying device state to users. In normal operation1 the device state can be determined using the table below:
|Power On Reset2||N/A||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 — Yellow-White-White||6||Battery over discharge|
|Red — White-White-White||7||DW1000 communication error|
|Red — Yellow-White-Yellow||8||Over temperature|
|Red — Yellow-White-Blue||11||Under temperature|
|Red — White-White-Yellow||14||Too hot while charging|
|Red — White-White-Blue||15||Too cold while charging|
|Red — Green-White-Yellow||16||Too hot to charge|
|Red — Green-White-Blue||17||Too cold to charge|
This condition indicates that the DWTAG battery has been discharged below recommended levels potentially damaging the battery. To rectify this condition the place the DWTAG on charge. To ensure best performance users should charge their DWTAG devices regularly.
This indicates that the DWTAG firmware is unable to communicate with the UWB transceiver. Plug DWTAG into USB host device to cause a system reset. If the problem persists please contact Ciholas for support.
The DWTAG will indicate over temperature error when it has reached a temperature that is potentially damaging to the device and battery. The device should be moved to a room temperature area and allowed to cool down before continued use.
The DWTAG will indicate under temperature error when it has reached a temperature that is potentially damaging to the device and battery. The device should be moved to a room temperature area and allowed to warm before continued use.
This indicates that the DWTAG reached a temperature that is potentially damaging to the device while charging. The device should be removed from charge and allowed to cool down before continued charging.
This indicates that the DWTAG reached a temperature that is potentially damaging to the device while charging. The device should be removed from charge and allowed to warm before continued charging.
This indicates that the DWTAG reached a temperature that is potentially damaging to the device while charging and automatically cut off charging. The device should be removed from charge and allowed to cool down before continued charging.
This indicates that the DWTAG reached a temperature taht is potentially damaging to the device while charging and automatically cut off charging. The device should be removed from charge and allowed to warm before continued charging.
