IQ-INT 3
I N T E R F A C E
T

®
IQ-INT 3 is an IQ System
®
interface that connects up to four different
IQ Bus loops to a host computer. It is
a self-contained unit with its own IQ Bus driv-
ers, RS232 drivers and power supply. It has a
microprocessor that can be directed by the host
computer to send and receive commands and
data to and from IQ components connected to
its IQ Bus loops.
The IQ-INT 3 supports both the original IQ
and the newer IQ
2
(Ucode) protocols. Conve-
nient RJ-45 connectors for IQ Bus input and
output make it easy to make system connec-
tions, allowing the use of off-the-shelf straight-
through network cables. Plus, the interface is
backed by Crown’s unequaled Three-Year, No-
Fault, Full Warranty that covers everything.

Specications
General
Internal Controls: A four-segment DIP switch
located on the rear panel is used to congure
the data rate for communication with the host
computer.
Connectors: IQ Bus Input: Four RJ-45 connec-
tors. IQ Bus Output: Four RJ-45 connectors.
(The IQ Bus Input and Output connectors are
grouped in pairs to accommodate four different
loops.) Computer: Female 9-pin “D-shell” con-
nector. AC Power: IEC320 connector for AC
power cord. All connectors are located on the
rear panel.
Indicators: A blue front and rear panel Power
indicator shows that the unit is plugged in and
receiving power. Yellow front and rear panel
indicators for each IQ Loop show loop data
activity.
Power Supply: Universal input switching power
supply.
Power Requirements: 100VAC to 240VAC, 47
Hz to 66 Hz.
Power Consumption:
60 Hz 50 Hz
100VAC 3.70W 3.71W
120VAC 3.92W 3.92W
220VAC 5.03W 5.03W
230VAC 5.23W 5.18W
240VAC 5.59W 5.41W
Crown Bus Data Communication
Protection: The auto-reset feature is controlled
by the microprocessor. Optically coupled
20-milliamp current loop receivers provide
ground isolation.
Data Rate: 38.4 K baud.
Data Format: Asynchronous 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: Variable from 200 to
3,000 feet (61 to 914 meters) depending on
wire capacitance. 1,000 feet (305 meters) is
typical with shielded 26 AWG twisted pair wire.
IQ repeaters or ber optic transceivers can be
used to cover greater distances.
Host Computer Data Communication
Data Rate: 9,600, 19,200, 38,400, 57,600 or
115,200 baud.
Data Format: Asynchronous binary serial data
with 1 start bit, 1 stop bit, 8 data bits and no
parity check.
Interface Type: RS232.
Operation: Half duplex.
Data Buffer: 255 bytes.
Intelligence: 16-bit microprocessor.
RS232 Transmission Distance: 50 feet (15.2
m).
Mechanical
Finish: Charcoal powder-coated steel chassis
and front panel with Lexan
®
front and rear over-
lays.
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.
Features
Connects up to four separate IQ Bus loops.
Blue Power indicators on the front and rear
panels.
Yellow Loop Status indicators on the front and
rear panels show IQ Bus loop data activity.
RJ-45 connectors for IQ Bus input and output
for easy and secure IQ Bus connections.
Supports both the original IQ and newer IQ
2
protocols.
The best three-year “No-Fault” full warranty
in the business!
