FCC

Class A Compliance

This equipment has been tested and found to comply with the limits for Class A Digital Devices, according to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used under the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. The user is cautioned that any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
Note: For a system to comply with FCC rules, all components in the system must comply. Please consult the instruction manuals of all components in an IQ System for FCC compliance.

INTRODUCTION

• The IQ-RPT repeater helps an IQ System® go the extra mile by increasing the length of a Crown Bus loop. It does this by reconstructing the data signal to prevent its degradation.
• With a Repeater in a system, 1,000 feet (305 meters) or more can typically be added to the operating distance of a Crown Bus. And because more than one repeater can be used on each loop, the potential is impressive.
• The Crown Bus is a serial communication loop designed to transmit IQ commands and data. As implemented in the IQ-RPT, it is a 20-milliamp current loop operating at 38,400 baud. To function properly, Crown Bus loops must be unbroken.
• The IQ-RPT works with all currently available Crown Bus interfaces. These interfaces include the IQ-PSI with one Crown Bus loop, the IQ-DRN-16 with two loops, and the IQ-INT II with 8 loops. IQ mixers (including the MPX-6, SMX-6, and AMB-5) also have a single-loop Crown Bus interface. Figure 1.2 shows an IQ-INT II with two connected Crown Bus loops.
• The IQ-RPT will typically extend a Crown Bus current loop by 1,000 feet (305 meters) or more. Up to 57 repeaters can be added to a single loop, so the total loop distance may reach 58,000 feet (17.7 kilometers).
• That’s almost 11 miles! Figure 1.3 shows a system with an IQ-INT II and repeater on its first Crown Bus loop.

Installation

• The installation of an IQ Repeater can be divided into two parts: power connection and Crown Bus connection.

Power Connection

• The IQ Repeater operates in one of two power settings.
• The 115 VAC setting is for operation from 100 to 120 VAC. Operation from 220 to 240 VAC uses the 230 VAC setting.
• The Repeater is factory set to the correct setting for the country to which it is shipped. Simply plug the correct power cord into the Repeater and an appropriate electrical outlet.
• Should the Repeater require a different power setting than the factory setting, contact qualified service personnel.

Connecting the Crown Bus

• IQ Repeaters are recommended at every point the Crown Bus exceeds 1,000 feet (305 meters). However, loops over 2,000 feet (610 meters) are possible without the use of a Repeater.
• The stringent characteristic determining maximum bus length is loop capacitance.
• Each loop should have less than 40 nanofarads of capacitance. Adding IQ Repeaters divides the bus loop into sections, each of which can then have 40 nanofarads of capacitance. (see Fig. 2.1.).
• When calculating bus capacitance, use the capacitance-per-foot rating of the loop wire and add 60 picofarads per IQ component.
• There are several connectors used for Crown Bus wiring, including DIN connectors and other bare wire connectors.
• The IQ Repeater uses a 5-pin DIN for input and a 4-pin DIN for the output. See Fig. 2.2 to connect IQ components with DIN Connectors. Figures 2.3 and 2.4 illustrate how to connect IQ components with DIN and barrier block connectors.

Operation

• There isn’t much to operating an IQ-RPT. Just plug it in and it works. The operating environment should be free of salt and moisture with temperatures between 32° and 158° Fahrenheit (0° to 70° Celsius).

• To help with troubleshooting, the Repeater provides several indicators that are described next.
  Power: This amber front panel LED lights to show that the unit is receiving AC power.

• Input Status: This green front panel LED flashes when incoming data is received.

• Output Status: This yellow front panel LED flashes when outgoing data is sent. It does not indicate the status of the output cabling.

• Output Continuity: This red back panel LED lights when there is a connection between the output of the Repeater and the input of the next device on the Crown Bus.

• It will not light unless current can flow in the Crown Bus output circuit from the positive (+) output line back to the negative (-) output line. (The negative output line is effectively a return line to ground.)

• The LED will not light if the output circuit is open, but it will light if the positive and negative output lines are shorted.

Specifications

General Connectors:

• AC Mains: 115-V units supplied with a 3-blade NEMA 5-15p cord. 230-V units require a customer-supplied IEC power cord.

Indicators:

Service

• This unit has very sophisticated circuitry which should only be serviced by a fully trained technician.

This is one reason why each unit bears the following label:

• CAUTION: To prevent electric shock, do not remove the covers.
• No user-serviceable parts inside. Refer servicing to a qualified technician.

Worldwide Service

• They will handle the necessary paperwork and repair.
• Remember to transport your unit in the original factory pack.

North American Service

• Service may be obtained in one of two ways: from an authorized service center or the factory.
• You may choose either.
• You must have your copy of the bill of sale as your proof of purchase.

Service at a North American Service Center

• This method usually saves the most time and effort. Simply present your bill of sale along with the defective unit to an authorized service center to obtain service.
• They will handle the necessary paperwork and repair. Remember to transport the unit in the original factory pack.
• A list of authorized service centers in your area can be obtained from our Technical Support Group.
