TECHNICAL DATA ORBAN MODEL 5518
Maximum Load Capacitance: 0.047 µ F (0

source impedance). Maximum cable length of
100 feet/30 meters RG–58A/U.
Filtering: RFI filtered.
Subcarrier (SCA) Inputs
Configuration: Two subcarrier inputs sum directly into composite baseband outputs;
COMPx LVL control settings have no effect on the absolute subcarrier levels.
Impedance: 600

SCA Sensitivity: Variable from <100 mV p-p to >10 V p-p to produce 10% injection assum-
ing 100% modulation = 4 V p-p at the 5518’s composite outputs. Rear-panel accessible
PC-board-mounted trim pots allow user to adjust the sensitivities of the two SCA inputs.
Connectors: Two BNC, shell connected to chassis ground, EMI suppressed.
19 kHz Pilot Reference: SCA2 input can be re-jumpered to provide a 19 kHz pilot reference
output.
Remote Computer Interface
Supported Computer and Operating System: IBM-compatible PC running Microsoft Win-
dows® 2000 (SP3 or higher), XP, Vista, or 7.
Configuration: TCP/IP protocol via direct cable connect, modem, or Ethernet interface.
Suitable null modem cable for direct connect is supplied. Modem and other external
equipment is not supplied.
Serial Connector: RS–232 on DB–9 male connector, EMI-suppressed. Uses PPP to pro-
vide for direct or modem connection to the 5518 PC Remote application.
Ethernet Connector: Female RJ45 connector for 10-100 Mbps networks using CAT5 ca-
bling. Native rate is 100 Mbps. Provides for connection to the 5518 PC Remote applica-
tion through either a network, or, using a crossover Ethernet cable, directly to a com-
puter.
Ethernet Networking Standard: TCP/IP.
Remote Control (GPI) Interface
Configuration: Eight (8) inputs, opto-isolated and floating.
Voltage: 6–15V AC or DC, momentary or continuous. +12VDC provided to facilitate use
with contact closure.
Connector: DB–25 male, EMI-suppressed.
Control: User-programmable for any eight of user presets, factory presets, bypass, test
tone, stereo or mono modes, analog input, digital input.
Filtering: RFI filtered.
Tally Outputs
Circuit Configuration: Two NPN open-collector outputs.
Voltage: +15 volts maximum. Do not apply negative voltage. When driving a relay or other
inductive load, connect a diode in reverse polarity across the relay coil to protect the
driver transistors from reverse voltage caused by inductive kickback.
Current: 30 mA maximum
Indications: Tally outputs can be programmed to indicate a number of different operational
and fault conditions, including Input: Analog, Input: Digital, Analog Input Silent, AES In-
put Silent, and AES Input Error.
