3.1.5 ETHERNET
Standard 10/100 Mbps RJ45 IP network communications input/output. Connect to a
local area network switch and/or to a gateway for access through the internet. This
interface automatically negotiates hardware interfacing, and a crossover cable is not
required. Direct connections to a PC or other network controller can be made with either
a crossover or straight Ethernet cable.
IP-based interfaces such as the built-in website and SNMP require this to be connected
and the network configured through the transmitter control center. There is no explicit
cap on the number of connections that can be made to the network controller; however
an excessive number of connections will cause a decrease in performance in any of these
IP interfaces.
3.1.6
AES
AES/EBU audio input connector. This XLR connector is used for inputting digital audio to
the standard stereo generator in the internal exciter. Select AES as the primary audio
source to modulate RF with this audio.
Supported bitrates are 32, 44.1, 48, and 96k.
3.1.7
LEFT and RIGHT
Left and Right balanced analog audio input connectors. These XLR connectors input
audio into the standard stereo generator system in the internal exciter. Set Analog L/R as
the primary audio source in order to modulate RF with this audio.
An internal hardware jumper allows these inputs to be switched to 10k Ohm
impedance.
3.1.8
COMP
Unbalanced composite audio input connector. This BNC connector allows input of
baseband audio up to 100 kHz into the internal exciter. Setting Composite as the
primary audio source modulates RF with this signal.
3.1.9
SCA1 and SCA2
Subsidiary Communications Authorization audio input connectors. These BNC
connectors allow subcarrier programs up to 100 kHz generated by external devices to be
injected in the internal exciter. These inputs are enabled and disabled independently.
3.1.10
RDS
Radio Data System input connector. This BNC connector allows input of an externally
generated RDS standard signal to broadcast time, station identification, and program
service information. This input is enabled and disabled independently.
3.1.11
19 kHz OUT
19 kHz stereo pilot output connector. This BNC connector is used to output the pilot
signal for optional use in external synchronization equipment. The output wave form is a
constant 1 V peak-to-peak sinusoid when connected to a high impedance termination.
3.1.12
EXC RF OUT
Internal exciter RF output connector. This BNC connector outputs the internally
generated exciter power level RF signal. For 1kW systems this should be jumped to PA RF
IN using a coaxial connector. For all other system types this should be connected to the
RF SPLT IN on the combiner module.
