IQ-RPT 3
The audio system shall utilize a separate component dedicated specifically
to prevent IQ loop signal degradation by reconstructing the incoming data
signal and repeating the reconstructed signal out to the next component on
the IQ loop. The repeater unit shall be capable of extending the operating
distance of an IQ loop by as much as 1,000 feet (305 m) or more, depend-
ing upon IQ loop wire capacitance. The repeater unit shall suport both the
original IQ and the newer IQ2 protocols.
The repeater unit shall provide one RJ-45 connector for input, and one
RJ-45 connector for output. The repeater unit shall provide Power indica-
tors on the front and rear panels to indicate that the AC supply is connected
and that power is applied. The repeater unit shall provide yellow Data Send
and green Data Recieve indicators on the front and rear panels to indicate
IQ loop data activity.
The repeater unit shall contain its own universal power supply for operation
from 100VAC to 240VAC, and 47 Hz to 66 Hz. A standard IEC inlet shall be
provided for AC line cord-set connection.
The repeater unit shall meet or exceed the following general specifications:
Power Consumption: 100VAC, 60 Hz: 3.70W, 50 Hz: 3.71W; 120VAC,
60 Hz: 3.92W, 50 Hz: 3.92W; 220VAC, 60 Hz: 5.03W, 50 Hz: 5.03W;
230VAC, 60 Hz: 5.23W, 50 Hz: 5.18W; 240VAC, 60 Hz: 5.59W, 50 Hz:
5.41W.
The repeater unit shall meet or exceed the following IQ Bus data com-
munication specifications: Protection: The auto-reset feature is controlled
by the microprocessor. Optically coupled 20-milliamp current loop receiv-
ers provide ground isolation. Data Rate: 38.4 K baud. Data Format: Asyn-
chronous binary serial data with 1 start bit, 1 stop bit, 8 data bits and
no parity check. Interface Type: 20-milliamp current loop. Operation: Half
duplex. Intelligence: 16-bit microprocessor. Transmission Distance: Vari-
able from 200 to 3,000 feet (61 to 914 meters) depending on wire capaci-
tance. 1,000 feet (305 meters) is typical with shielded 26 AWG twisted pair
wire. More IQ repeaters or fiber optic transceivers can be used to cover
greater distances.
The repeater unit shall meet or exceed the following mechanical specifica-
tions: Finish: Charcoal powder-coated steel chassis and front panel with
Lexan
®
front and rear overlays. Dimensions: 19-inch (48.3 cm) standard
rack mount width (EIA RS-310-B), 1.75-inch (4.4 cm) height and 6.5-inch
(16.5 cm) depth. Weight: 6 lbs., 4 oz (2.8 kg) net; 9 lbs., 5 oz (4.2 kg)
shipping.
The repeater unit shall be designated the Crown IQ-RPT-3 .
