3.4.2 Mini-RX beacon
The Mini-RX Beacon can be used in both the Non-Inverse
Architecture (NIA) and in the Inverse Architecture (IA): NIA and IA
comparison
The Mini-RX beacon HW differs from the regular Beacon HW v4.9
in several ways:
- It is an RX-only beacon, i.e. it can receive, but it cannot
transmit ultrasonic signal
- The fact that it is RX-only makes it far more sensitive, i.e. you will get a longer range
between Beacon HW v4.9 and Mini-RX v5.xx than between Beacon HW v4.9 and
Beacon HW v4.9
- Mini-RX beacon can receive any ultrasonic frequency from the bands: 19kHz, 25kHz,
31kHz, 37kHz, 45kHz. The filter can be simply selected in the Dashboard. At the same
time, the working ultrasonic frequency of Beacon HW v4.9 is HW-defined by ultrasonic
sensors and can’t be changed
- Mini-RX beacon can receive several ultrasonic frequencies at once. That is used in
Inverse Architecture. See the comparison: NIA and IA comparison
- The Mini-RX Beacon is significantly smaller than Beacon HW v4.9
- Can play a role of stationary beacon when imputing coordinates manually
- Can play a role of mobile beacon (in IA system)
- Has digital microphone, which is more sensitive than regular sensors
- Supports 868/915MHz radio only
- Light weighted
- Can be water-protected
- The component of the Marvelmind Helmet and Marvelmind Watch
- It has 360° reception angle (horizontally) and 180° reception angle (vertically)
Reception diagram. Digital microphone has about 360° (horizontally) and 180°
(vertically) reception angle
Mini-RX beacon may be over discharged. In that case do the following:
Turn off the beacon with DIP switches and charge it for 1 hour. Then turn the beacon on,
flash the latest SW via DFU Programming and charge it for 1 hour again
