5 Specifications

General

Controls: A four-segment DIP switch located on the
rear panel is used to configure the data rate for com-
munication with the host computer. Factory default
setting is 115,200 baud.

Connectors: IQ Bus Input: Four RJ-45 connectors. IQ
Bus Output: Four RJ-45 connectors. (The IQ Bus Input
and Output connectors are grouped in pairs to accom-
modate four different loops.) Computer: Female 9-pin
“D-shell” connector. AC Power: IEC320 connector for
AC power cord. All connectors are located on the rear
panel.

Indicators: A blue front and rear panel Power indica-
tor 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 sup-
ply.

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 up to 3,000 feet
(914 meters) depending on wire capacitance. 1,000
feet (305 meters) is typical with shielded 26 AWG
twisted pair wire. IQ repeaters or fiber optic transceiv-
ers 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 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,
Net: 6 lbs., 4 oz (2.8 kg);
Shipping: 9 lbs., 5 oz (4.21 kg).
