Wat is die CommuniNet MND-1420?
Die CommuniNet MND-1420 is 'n hoë-krag (20W) TDD (Tydafdeling Dupleks) draadlose transmissiestelsel wat in die 1350–1470 MHz-band werk. Dit is deel van die CommuniNet professionele dataskakelprodukfamilie en is spesifiek ontwerp vir langafstand, Lae-latency, en hoë-betroubaarheid kommunikasie.
Danksy sy gevorderde RF-ontwerp en intelligente skakelbestuur, die stelsel kan bereik:
- 150 km+ lug-tot-grond-oordragreeks met omnirigting-antennas (siglyn)
- 200 km+ reeks wanneer hoë-aanwins directional gebruik word (pleister) antennas
Dit maak dit 'n sterk keuse vir industriële UAV's, langdurige hommeltuie, en vaste afgeleë kommunikasiestasies.
Sleutelkenmerke van die MND-1420 TDD-draadlose stelsel
1. Intydse interferensie-opsporing
The system continuously monitors the RF environment to identify background noise and interference. It helps users optimize antenna placement and avoid electromagnetic interference sources to ensure a clean and stable link.
2. Aanpasbare frekwensiekeuse
When interference is detected, the module can intelligently switch to cleaner frequencies within the operating band, ensuring uninterrupted communication even in complex RF environments.
3. Aanpasbare bitsnelheid en stroombeheer
The MND-1420 dynamically adjusts data rates and stream quality based on real-time link conditions. This ensures stable transmission without sudden dropouts, even over extreme distances.
4. Outomatiese heruitsending
Lost packets can be automatically re-sent, significantly improving reliability for control signals, telemetrie, and video streams.
5. Outomatiese kragbeheer
The system intelligently manages transmission power to balance range, stabiliteit, and thermal efficiency.
Hardeware-ontwerp en koppelvlakke
The CommuniNet MND-1420 uses an industrial-grade J30JZ-25-pin aviation connector, designed for harsh environments and vibration-resistant installations.
Beskikbare koppelvlakke:
- 1× Power supply input
- 2× Ethernet ports (LAN1 / LAN2)
- 3× Serial ports
- 1× RS-422
- 2× RS-232 / TTL
- SBUS support
- 2× SMA antenna connectors
This rich interface set makes the module highly flexible for integration into UAVs, unmanned ground vehicles (by UGV), boats, and fixed wireless stations.
Intelligente LED-statusaanwysers
The device uses multiple LED indicators to provide instant system feedback:
- PWR (Green) – Indicates power status
- SYNC (Green) – Blinking means not synchronized; steady light means successful link
- LAN1 / LAN2 LEDs – Blink during network data transmission
- RSSI LEDs – Display signal strength:
- Strong signal: around -45 dBm
- Medium signal: around -80 dBm
- Weak signal: around -95 dBm
These visual indicators allow users to quickly diagnose link quality in the field without special tools.
Agtergrondgeraasopsporing verduidelik
One of the advanced features of the MND-1420 is background noise detection via the built-in web analyzer.
- Red line: Noise floor at the master device
- Blue line: Noise floor at the slave device
A lower (more negative) dBm value means a cleaner RF environment.
Byvoorbeeld:
- -100 dBm → Excellent, low interference
- -70 dBm → Heavy interference
This function helps users reposition antennas or move away from strong electromagnetic sources to achieve optimal performance.
