PRELIMINARY DATA SHEET
USX2
NBFM Multi-channel UHF Transceiver
USX2 is small multi-channel half duplex
UHF transceiver available for operation on
315MHz, 433MHz and 458MHz bands with
the user programmable RF power output of
www.DataSheuUet4pSUX.tcoo2m1o0f0fmerWs .up to 128 frequency channels
in 25kHz channel spacing. USX2 also
features dual VCO which allows
transmitter section to be operated on one
frequency while receiver on another.

NOTES:
1. No inversion occurs between TXD and RXD. However AF out is inverted relative to TXD.
2. Parallel channel selects (P0-P3) and TXE are active LOW and have 47kinternal pullups to 3V
3. Open collector output RXD has a 47 kpullup to 3V.
4. The software incorporates a 1200 baud modem, compatible with that implemented in other
Radiometrix narrowband units ( i1200 tones and format ). Modem operation is selected by serial
command.
5. Main serial port (P0, P3) operates at 9600 baud. (Command set is not the same as TR2M, SMX
families). The unit is capable of operating in 'basic' parallel channel select only mode, or in serial
controlled 'expanded' mode
6. Transmit power can be set by serial command
7. RSSI can be read back as a digital value. (on P3)
8. If analogue transmit modulation is needed, then connect a series 1µF cap + 500ktrimmer (a
multiturn is advised) in the TXD circuit. Adjust trimmer for 90% of peak deviation (+/- 2.7KHz) at
mean input level.

Notes: 1. The data slicer cannot be depended upon for data waveform frequencies below 250Hz
2. When RX is on and a transmitter keys up, again a 50ms period is required to stabilise data
output mark/space. i.e. allow at least 50ms of preamble
