1 GENERAL SAFETY INFORMATION
The information that follows, together with local site regulations, should be studied by
personnel involved with the operation or maintenance of this equipment, to ensure awareness
of potential hazards.
WARNING- RF Power Hazard: High levels of RF power are present in the unit. Exposure to RF or
microwave power can cause burns and may be harmful to health.
Switch off supplies before removing covers or disconnecting any RF cables, and before inspecting
damaged cables or antennas.
Avoid standing in front of high gain antennas (such as a dish) and never look into the open end of a
waveguide or cable where RF power may be present.
Users are strongly recommended to return any equipment that requires RF servicing to RF Central.
WARNING- GaAs / BeO Hazard: Certain components inside the equipment contain Gallium Arsenide
and Beryllium Oxide that are toxic substances. Whilst safe to handle under normal circumstances,
individual components must not be cut, broken apart, incinerated, or chemically processed. In the
case of Beryllium Oxide, a white ceramic material, the principal hazard is from the dust or fumes which
are carcinogenic if ingested, inhaled, or entering damaged skin.
Please consult your local authority before disposing of these components.
CAUTION - Tantalum Capacitors: When subjected to reverse or excess forward voltage, ripple
current or temperature these components may rupture and could potentially cause personal injury.
CAUTION: This system contains MOS devices. Electro-Static Discharge (ESD) precautions should be
employed to prevent accidental damage.
RFX-RMR Issue 1.0 page 4 of 41
1.1 Health & Safety
Exposure to Non-Ionizing (RF) Radiation/Safe Working Dista nce s
The safe working distance from a transmitting antenna may be calculated from the relationship:
PT. GR
√
D =
In which D = safe working distance (meters)
PT = transmitter or combiner power output (watts)
GR = antenna gain ratio = anti log (gain dBi ÷10)
w = power density (watts/square meter)
The RF power density value is determined by reference to safety guidelines for exposure of the
human body to non-ionizing radiation. It is important to note that the guidelines adopted differ
throughout the world and are from time-to-time re-issued with revised guidelines. For RF Central use,
a maximum power density limit of 1w/m² is to be applied when calculating minimum safe working
distances.
Important Note: It must be remembered that any transmitting equipment radiating power at
frequencies of 100 kHz and higher, has the potential to produce thermal and athermal effects upon the
human body.
To be safe:
a) Operators should not stand or walk in front of any antenna, nor should they allow anyone else
b) Operators should not operate any RF transmitter or power amplifier with any of its covers

RFX-RMR Issue 1.0 page 5 of 41
1.2 Maximum RF Power Density Limits
The RF Radiation Power Density limit figure recommended by RF Central is based upon guideline
levels published in:
a. IEEE standard C95.1 1999 - IEEE Standard for Safety Levels with respect to Human Exposure
to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.
b. Guidelines for Limiting Exposure to Time-varying Electric, Magnetic & Electromagnetic Fields
(up to 300 GHz) published in 1998 by the Secretariat of the International Commission on Non-Ionizing
Radiation Protection (ICNIRP).
Both documents define guideline RF power density limits for "Controlled" and "Uncontrolled"
environments. An uncontrolled environment is defined as one in which the person subjected to the RF
radiation may be unaware of and has no control over the radiation energy received. The uncontrolled
environment conditions can arise, even in the best-regulated operations and for this reason the limits
defined for the uncontrolled environment have been assumed for the RF Central recommended limit.
Documents a) and b) also show the RF power density guidelines to be frequency dependent. Different
power density / frequency characteristics are presented in the two documents. To avoid complexity
and to avoid areas of uncertainty, RF Central recommends the use of a single power density limit
across the frequency range 100 kHz to 300 GHz. The 1w/m² power density limit we recommend
satisfies the most stringent of the guidelines published to date.

5 FRONT PANEL CONTROLS
Front panel view of the RFX-RMR
The front panel of an RFX-RMR comprises two 2-way switches (On/Off and Analog/Digital), a 10-way
rotary switch (BAS channel number), six push button switches (used to navigate the various RFXRMR menus) and an LCD display.
Also fitted are three LEDs – ‘DC’ (Green), ‘Status’ (bi-color green/red), and ‘Local’ (bi-color green and
amber)
On/Off Switch Down for Off, up for On
Digital/Analog switch Down = Analog transmission, Up = Digital transmission. This function
can also be controlled via the push buttons and RFX-RMR menus.
Channel Rotary, 0-10. 1= BAS channel 1, 2 = BAS channel 2, etc to 0 = BAS
channel 10. Please note that the BAS channels can be switched between the ‘current’ plan and the
‘new’ plan via the push buttons and RFX-RMR menus. The exact frequency selected by either method
is shown on the top menu page on the LCD display.
‘DC’ LED Lit green whenever a correct DC voltage is presented to the RFX-RMR
Receiver. This LED will be lit irrespective of whether the unit is switched ‘on’ or ‘off’.
Status LED Stable Green indicates that the RFX-RMR is functioning correctly. A
flashing green light indicates that the RFX-RMR is functioning correctly but that no valid RF signal is
present at the input to the receiver. A stable red light indicates that the unit has an alarm condition.
Local LED Indicates whether the ‘channel’ and ‘analog/digital’ switching controls are
being accepted from the front panel rocker switches or from the push button menu. Green light =
rocker switch operation, amber light = push button menu operation.
Full details of the push button menu structure can be found in section 8.

8 INTRODUCTION
The RFX-RMR X-0101 board provides the analog receiver function of the RMT digital / analog
receiver system rack assembly. The board provides one (NTSC) video output and two audio outputs.
Operation modes and audio sub carrier frequency selection is via front panel control. The R.F. input to
the board, at 70MHz, is taken from the system common digital / analog IF / AGC circuit via a passive
splitter network on the unit motherboard. A range of video processing options are available via front
panel selection or on-board switches. On-board LED’s are provided for audio 1 and 2 phase locked
loop and power supply monitor functions.
8.1 R.F. input circuit operation.
The 70MHz R.F. input at Skt.1 is set to –17dBm nominal.
8.2 Base-band video processing
Provides facilities for video de-emphasis, black level clamp, automatic deviation selection, video invert
and audio sub-carrier filtering.
8.3 A1 and A2 audio demodulators
The nominal sub carrier input frequency ranges are A1 = 4.5 – 5.1MHz, A2 = 5.5 – 6.2MHz. The audio
demodulators have a 75uS characteristic, to match the pre-emphasis characteristic of the RMT
Transmitter.
RFX-RMR Issue 1.0 page 21 of 41
8.4 Analog demodulator Power supplies and monitoring

I2C to all
The Front Panel / Display Controller is the main system controller for the unit. All configurations of the
unit hardware are from this board. An I
2
C two-wire interface is used to communicate with all other
intelligent devices within the unit. This carries the command data and reads back status data from all
boards within the unit.
All configuration parameters, video settings, audio settings, frequencies etc. are held on this board.
This allows the ability to remove and change other boards within the unit without the loss of set-up
parameters.
At power-up this board initializes all the other boards and during normal operation monitors all the
major functions and reports any problems as part of the unit status.

8.7 RFX-RMR - Power supplies and monitoring
The RFX-RMR power supply is mounted on the under-side of the Mother Board. See photograph in
section 8.6
The +12v input supply is filtered and regulated by IC7, +5v linear regulator. This provides the +5 volt
supply to the Receiver board circuits and is also the reference voltage for the discrete ‘low drop out’
10.5-volt regulator circuit comprising TR3, TR6, TR7, and associated components.
The +10.5v supply provides the board circuits and the DC /DC converter IC16. The converter provides
the –4.3v supplies for the board.
The +5v supply is current limited by the inclusion of R56, R57 in the supply to IC7. The +10.5v supply
is current limited by TR4 and sense resistors R46, R47. Supply over voltage protection is controlled by
TR5. The +10.5v regulator circuit is turned off if the input supply exceeds ~15.5v.
The input supply monitor circuit (IC12) and ‘12v OK’ bi – color LED are designed to indicate supply OK
between 10.5 and 15.5v. Over this range the LED will be illuminated green. Above and below these
limits the LED will illuminate red.
