Hardware

Anchor for Ranging / RTLS applications with radino32 DW1000 Ultra Wide Band module.

DW1000 Anchor


Features:

  • radino32 DW1000 module
  • Integrated UWB antenna
  • Vin 9-48V DC
  • Enclosure IP 65
  • RS485 Interface for data and setup
  • 1x Relay 10A/250VAC, NC/NO-function switchable by jumper
  • Connection: RS485(A/B/GND), Vin(9-48V), GND, 2xRelay


Software

The DW1000 Anchor will be shipped with a closed source demo-firmware.


Functionality of demo-firmware

  • Shows data of received Tags on RS485-interface in a readable format:
  • TAG-ID, distance, signal strength.
  • If a TAG is inside a secure distance of 2 meter, the relay is triggered
  • Fix HF-setup (channel, band width, transmitting power)


Working with the demo-firmware command mode

  • Connect the DW1000 Anchor to your PC via RS485 (e.g. USB-RS485-Bridge)
  • Connect VCC (9-48 V) and GND to DW1000 Anchor
  • Start a terminal program (e.g. PuTTY, HTerm, Hyperterminal, ...) with 57600 baud and 8N1
  • After opening the connection type "m" and press <Enter> once to display the menu

Available commands:

All commands will be send by <Enter>.

cX
  • set channel to X. (Valid values: 1,2,3,4,5,7)
xYYZ
  • set tx power to YY.Z dB (Range 0 to 33.5 steps of 0.5)
p
  • toggle state of relais when a tag is within distance
dXXX
  • set distance below which a tag is considered near (XXX is the value in 10ths of a meter)
    • example: d55 <Enter> sets the distance to 5.5 meters
t
  • toggle if information is printed as table (Y) or as single measurements (N)
r
  • reload last stored values from eeprom
s
  • store current configuration to eeprom
q
  • leave command mode


Output formats

Table output format:

Type Address Range  Battery OthRxP     OurRxP     (ADDR=1815) E
2    1979    1.42 m 4.14 V  -63.23 dBm -62.58 dBm
  • ADDR=1815 means we are the Anchor with ID 1815
  • Type 2 means tag
  • Address is the tags ID
  • Range is the distance to the tag in m
  • Battery is the current battery voltage the tag measures
  • OthRxP is the Received Signal Strength Indication reported by the distand device
  • OurRxP is the Received Signal Strength Indication our DW1000 measured


Single output format:

$RAN,373024,1979,1.14,4.12,-62.23,-63.30
  • $RAN - Header
  • Milliseconds since Anchor power up
  • ID of the tag
  • Distance to the tag in meters
  • Batterylevel the tag measures
  • RSSI of the connection reported by the distant device
  • RSSI of the connection reported measured by our DW1000
