Environmental Conditions
-
درجة حرارة التخزين: -40درجة مئوية إلى +85 درجة مئوية
-
درجة حرارة التشغيل: -40درجة مئوية إلى +55 درجة مئوية
-
رطوبة: 5%–95%
هوائي & 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
-
نقل الطاقة
-
Measured at room temperature, مع 24العرض الخامس, 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
-
-
توصية: For efficiency and heat management, use 24V supply.
مزود الطاقة
-
Do not operate the device above the allowed supply voltage limit.
استهلاك الطاقة
-
القوة القصوى: Measured at room temperature, 24العرض الخامس, normal transmission mode; actual usage may be 92–95% of max.
-
Standby Power: Measured at room temperature, 24العرض الخامس; represents power consumption when connected but idle.

-
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.
-
ملحوظة: Outdoor IP65 models do not support extended range mode.
