PS-8810
DIGITAL SIGNAL PROCESSOR
An IQ host computer is a PC running Microsoft Windows 95, 98,
ME, 2000 or NT that is used to configure, control or monitor an IQ
System. Depending upon the design of your IQ System, it may or
may not require a host computer during normal operation. Third
party control systems such as AMX can also be used but, need
some fundamental programming before they are able to access the
PS-8810’s features.
How the BSS PS-8810 will be used will determine whether or not
it will need to be connected directly to a host computer. If the
unit is to be connected to an ‘IQ Loop’ it will not necessarily
need to be connected directly to a host computer. The following
circumstances require connection to a host computer:
• If an IQ Loop is not to be used, the BSS PS-8810 will need
to be connected to a host computer so that the unit can be
configured. Afterwards, if computer control is not required,
the host computer can be disconnected.
• If the BSS PS-8810 is to be configured before it is installed
into an IQ System, it must be connected directly to a host
computer for configuration. The onboard memory of the
unit will maintain its configuration without it being plugged
into an AC source.
• If the BSS PS-8810 is to be used as an IQ interface for other
IQ System components, it will need to be connected
directly to a host computer for configuration of other
components during setup, and for IQ control of components
during normal operation.
One of the advantages of connecting directly to a host computer
is that a separate IQ interface (i.e. Crown IQ_INT-3) is not required.
If you plan to configure the unit while it is connected to the IQ
Loop, skip ahead to Step 2.
RS232 is commonly used with PCs, and is the communication
standard supported by the BSS PS-8810 when used as an
interface. Because it uses unbalanced signal wiring, it cannot be
used for distances over 50 feet (15.2 m).
The following illustration shows how to wire the serial cable:
