be equal to the actual purchase price, not including interest, insurance,
closing costs, and other finance charges less a reasonable
depreciation on the product from the date of original purchase.

The

host computer is not detected. In this mode the AUX
port will still be available for use, but the RS232 serial
port will be inactive. In addition, the unit’s Crown Bus
input and output will be closed to allow the normal flow
of communication around the Crown Bus loop.
Commands received at the unit’s Crown Bus input will
be analyzed and executed if they are addressed to the

to a non-IQ component. For example, the AUX port
can be connected to a relay to turn on and off a remote

logic signals. Whether the

This manual will help you successfully install and use
this new interface. We strongly recommend you read
all the instructions, warnings and cautions. Also, for
your protection, please send in the warranty

1.1 Unpacking

Please unpack and inspect the 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 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.

A. Power Switch

This two-position sliding switch turns the unit on and off.
Slide the switch toward the serial cable to turn it on. When
first turned on, the green Enable indicator (D) will glow
brightly and the yellow DSPI (C) will “wink” twice to show
that adequate voltage is available.

B. RS232 Computer Connector & Cable

A female 9-pin “D-shell” connector and 16-inch (41-cm)
cable is provided for serial connection to a host com­puter. The RS232 communication standard is supported.

Note: A 9-pin to 25-pin adapter will be required if the
serial port of the host computer has only a 25-pin connec­tor.

The

IQ–PSI

is configured so that if an active computer
is plugged into the RS232, the PSI detects that the RTS is

domestic units only) to this male coaxial DC power con­nector. It requires a plug with an outside diameter (O.D.)
