Hardware Installation; Connecting To A Host Computer (Step 1) - Crown AMB-5 Hardware Installation Manual

3 Hardware Installation

The installation of an IQ mixer/multiplexer consists
of two major parts: installing the hardware and con-
figuring the software. This manual deals only with
hardware installation. Refer to the appropriate soft-
ware manual for instructions in setting up and oper-
ating your unit.
Provide adequate cooling if the unit will be used in a
hot environment. Allow one empty rack space (1.75
inches or 4.4 cm.) between each unit if more than
four units will be stacked in a cabinet. Each empty
rack space should be sealed with a blank rack
panel.
The hardware installation is divided into 4 steps:
1) connecting to a host computer, 2) connecting to
the Crown Bus, 3) connecting the audio inputs and
outputs and 4) connecting auxiliary devices.

3.1 Connecting to a Host Computer (Step 1)

An IQ host computer is an IBM
Apple ® Macintosh computer which is used to con-
figure or control/monitor part or all of an IQ System .
Depending upon the design of your IQ System , it
may or may not require a host computer during
normal operation.

How the mixer/multiplexer will be used will deter-
mine whether or not it will need to be connected
directly to a host computer. If the unit will be con-
nected to the Crown Bus it will not need to be
connected directly to a host computer. The following
circumstances require connection to a host com-
puter:
• If a Crown Bus will not be used, the mixer/mul-
tiplexer will need to be connected to a host
computer so the software inside the unit can
be configured. Afterward, if manual control is
not required, the host computer can be discon-
nected.
• If the mixer/multiplexer must be configured be-
fore it is installed into an IQ System, it must be
connected directly to a host computer for con-
figuration. The onboard battery of the unit will
maintain its software configuration for up to 60
days without it being plugged into an AC
source.
• If the mixer/multiplexer will be used as an IQ
interface (Option 1) it will need to be con-
nected directly to a host computer.
One of the advantages of connecting directly to a
host computer is that a separate IQ interface (IQ-
INT) is not required. If you plan to configure the unit
