Description
The output power is programmable up to 35W. (15W for European version) It takes incoming data, modulates it with GMSK, FSK, PSK or most spectrum efficient QAM modulation and transmits it at RF power output levels from 13 dBm up to 33 dBm operating in 406 to 470 MHz. The UHF transceiver is also capable of receiving RF signals through a 50 Ohm impedance external antenna port. These signals are demodulated and output to the RS-232 serial port. AW435BT delivers a reliable radio link at up to 38.4 kbps over the air for the 25 kHz channel spacing, 30 kbps for 20 kHz, 19.2 kbps for 12.5 kHz, and 9.6 kbps for 6.25 kHz. The unmatched features of AW435BT include data scrambling, frequency hopping, user selectable transmit output power level, low power consumption sleep modes, auto scanning for base. The unit’s user settings can be changed through the built-in Command Line interface (CLI), or through AWLaunch.
The Aw435 is fully compatible with most survey industry protocols like:
– Satel 3AS(D)
– Pacific Crest
– TrimTalk
