12. USB Socket. RDS content main content update. Connect a
Windows
TM
PC (running the manufacturer’s free software application)
to this port. Use a high-quality USB cable, of 1metre or less in length.
13. MPX IN. If using an external processor and RDS encoder, or a
baseband MPX Studio-Transmitter Link, connect to this BNC. Adjust the
output level of the external equipment to provide the correct
modulation level (requires test equipment).
14. MPX OUT. To broadcast audio connected to the transmitter, with
the internal audio processing and RDS data applied, connect the
supplied patch lead between this ‘MPX OUT’ socket and the ‘MPX IN’
BNC socket.
15. POWER. Connect a power lead with an IEC C13 connector (and a 5
amp fuse in the plug or at the distribution panel) to this socket. Two T2
amp (time delay) fuses are fitted within this connector’s Fuse carrier.
16. EARTH. Grounding connection point (M4 stud and bolt).
Pin 9. RF Mute Control. Supplying between 5 and 12V this pin to
(with reference to chassis ground potential) will mute the RF
output. Primarily used in automated changeover systems.
Pins 7 and 8. GND connection, at chassis earth potential.
The above ‘Open Collector’ outputs are capable of operation up to 50V
and sinking a current of 75mA maximum. The normally high, (ie. ‘pull
low’ upon alarm condition) provides inherent ‘power failure’ or ‘cable
connection failure’ signalling.
10. MPX IN. If using an external processor and RDS encoder, or a
baseband MPX Studio-Transmitter Link, connect to this BNC. Adjust the
output level of the external equipment to provide the correct
modulation level (requires test equipment).
11. POWER. Connect a power lead with an IEC C13 connector (and a 5
amp fuse in the plug or at the distribution panel) to this socket. Two T2
amp (time delay) fuses are fitted within this connector’s Fuse carrier.
12. EARTH. Grounding connection point (M4 stud and bolt).
