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.

ccc = a channel number from 00 to 127
aa = a two digit channel number from 00 to 15
nnnnn = synthesizer N register value, (up to 65535)
rrrrr = synthesizer R register value, (up to 16383)
pp = power setting value (0 - 30)
i = table step (increments of N) (0-7)
ooooo = receive mode frequency offset
eee = power calibration figure
N = channel frequency / (13MHz / R)
13MHz / R = 25KHz , so R = 520 (usually)
receive offset = 21.4MHz / (13MHz / R) , so = 856 (usually)
www.DataSheetA4Up.caoumse of at least 50mS must be allowed after operations which result in eeprom programming operations
(all except NDIV, RDIV, GOTO, PSET and RSSI). This allows the programming cycle to complete.
Instructions marked ' # ' output a three byte ' OK<cr> ' sequence after sucessfully completing their eeprom
programming cycles
When first powered up, the unit will operate on channel and output level specified by the last CHAN and
POWER instructions, irrespective of previous NDIV, RDIV, CHAN or PSET operations)

( = byte -128) (volatile)
single read of RSSI (output on P3)
single byte read, as for IDENT command
222 reception of 16 consecutive 222 bytes returns radio to serial mode.
This mode of operation is intended to provide a simple, fast, serial command mode.
4. Modem. Commands are interpreted as in SERIAL mode (and 'short' mode may be selected.) In this
mode the unit operates as a simple 1200 baud packet modem, with TXD (in) on P2 and RXD (out) on P1.
The N_TXE pin does not control tx switching in this mode, but rather the presence of valid data in the tx
buffer initiates a transmit burst. No handshaking is provided, and the unit has a sufficient over-link data rate
to transparently 'stream' continuous data. Error correction, re-transmission of corrupt packets and addressing
are not provided.
This mode is compatible with other Radiometrix 'i 1200' mode equipment, including the narrow band eval
kit.
Notes:
Unlike in the RLC and TLC units, the LOCKSERIALMODE (and FAST) commands are non-volatile. Once a
serial mode is selected, the unit will power up in this mode until a PARALLEL command is received.
The command interpreter IS case sensitive. Use upper case.
Spaces are optional (they are not decoded), provided the command line does not exceed 16 characters.
When manually programming this unit we recommend setting your terminal to local echo. The 'backspace'
key functions normally.
All serial communications use 9600baud 'inverted RS232' 8 bit data, no parity, 1 start bit, 1 or 2 stop bits
A simple 'driver' program will be made available to simplify programming of these units, if desired.
RSSI read operations only function correctly if the unit is in RX mode (n_TXE pin is high or floating)
