RX10 Ten-Zone Receiver Decoder
Some major points to consider when installing equipment:
1. Never install antennas near or adjacent to telephone, public address or data
communication lines, or overhead power cables.
2. Avoid, wherever possible, running antenna coax alongside other cables and avoid kinks and
coils. Pre-terminated cable should not be altered.
3. Avoid mounting the receiver in the immediate vicinity of telephone exchanges or computer
equipment.
4. Always use 50 ohm coaxial cable between the antenna and the receiver. If cable runs
exceed 5 meters, always use low loss 50 ohm cable such as RG213 or UR67 to a maximum
of 15 meters.
Coaxial cable intended for TV, Satellite or CCTV installations is normally 75 OHM
and therefore totally unsuitable for any receiver installation manufactured by
Scope.
5. Also remember that the performance of the system will be affected by the type of material
the unit is mounted on and its surroundings.
The following is a list of materials that this receiver will be adversely affected by if
mounted on or if mounted in close proximity to:
a) Foil back plasterboard
b) Metal mesh or wire reinforced glass
c) Metal sheeting, large mirrors or suspended ceilings
d) Lift shafts
All of the above can reflect radio waves and thereby reduce the capability of the receiver to
perform its desired functions.
6. The circuit boards within this equipment may be harmed by Electrostatic Discharge (ESD).
Installers should ensure that both themselves and the system’s chassis are grounded before
beginning any installation and should ensure that adequate anti-static procedures are
adhered to at all times.
Fit the required switch cables to the appropriate relays. These are labeled Zone 1 to Zone 10 and Common
(the Common relay operates when any zone is triggered). Terminals are available on each relay for
Normally Open, Normally closed and Common.
Finally, connect the blue latching power connector to a 12V DC @ 0.7A power supply, observing the correct
polarity, as shown in diagram 1.
To program and configure the unit, the 9 way D connector must be connected to a COM port on a PC using
a standard 9 way serial cable (see Section 3, Programming Utility). This port can also be used to connect
the unit to a serial printer or PC for data logging purposes, or to a Scope transmitter for repeater
application.
