Environmental Conditions

• دمای ذخیره سازی: -40درجه سانتی گراد تا +85 درجه سانتی گراد

• دمای عملیاتی: -40درجه سانتی گراد تا +55 درجه سانتی گراد

• رطوبت: 5%–95%

Antenna & RF Considerations

• Each antenna port must not receive signals >10 dBm when active, otherwise permanent damage may occur.

• Recommended minimum distance between module antennas is greater than the device port spacing; ideally, module antennas should be spaced >2 meters apart.

• Continuous operation requires proper heat dissipation:

  • CPU/core temperature ≤100°C

  • Casing temperature ≤80°C

انتقال قدرت

• Measured at room temperature, با 24عرضه V, in normal transmission mode.

• <33 dBm series: Uses DCDC conversion for low-voltage power to the PA; voltage fluctuations do not affect maximum output power.

• ≥33 dBm series: PA voltage follows supply voltage. Increasing supply above 24V to the allowed upper limit (see typical rating table) will:

  • Increase system power consumption by 10–25%

  • Increase max transmit power by ~0.1 dB for 33 dBm units, ~0.3–1 dB for >33 dBm units

• توصیه: For efficiency and heat management, use 24V supply.

منبع تغذیه

• Do not operate the device above the allowed supply voltage limit.

مصرف برق

• Maximum Power: Measured at room temperature, 24عرضه V, normal transmission mode; actual usage may be 92–95% of max.

• Standby Power: Measured at room temperature, 24عرضه V; represents power consumption when connected but idle.

رابط های داده

• LAN: 10/100 Mbps

• RS232: Up to 115200 bps

• TTL: 3.3 V level, up to 460800 bps

• TTL/SBUS: Only one selectable at factory

Extended Range Mode

• Boosts rated maximum output by 1–2 dB to achieve longer range.

• Increases system power consumption by 10–30%.

• Proper heat dissipation is required; PA linearity may degrade, MCS8 and MCS7 may not be supported.

• Note: Outdoor IP65 models do not support extended range mode.

Recommended Use Distance

• خط دید, interference-free conditions, 1.4 GHz band:

  • Sky-side: 2 dBi omnidirectional antenna

  • Ground-side: 5 dBi omnidirectional antenna

• Can reliably stream 2–4 Mbps video on a single channel
