1 Welcome
The IQ-INT II is an IQ System interface that connects up
to eight different Crown Bus loops to a host computer. It
is a self-contained unit with its own Crown Bus drivers,
RS232/RS422 drivers and power supply. It has a
microprocessor that can be directed by the host
computer to execute commands, and it can send and
receive commands and data to and from IQ components
connected to its Crown Bus loops.
This manual will help you successfully install and use
your new interface. Please read all instructions,
warnings, and cautions. Also, for your protection, please
send in the warranty registration card today and save
your bill of sales as it is your official proof of purchase.

1.1 Unpacking

Please unpack and inspect the new interface for any
damage that may have occurred during transit. If
damage is found, notify the transportation company
immediately. Only you, the consignee, may initiate a
claim for shipping damage. Crown will be happy to
cooperate fully as needed. Save the shipping carton as
evidence of damage for the shipper's inspection.
Even if the unit has arrived in perfect condition, as most
do, save all packing materials so you will have them if
you ever need to transport the unit. NEVER SHIP THE
UNIT WITHOUT THE FACTORY PACK.
