PS-8810
DIGITAL SIGNAL PROCESSOR
The ‘IQ Loop’ is a serial communication loop for transmitting IQ
commands and data between multiple IQ compatible units. It
provides excellent flexibility, allowing a IQ Loop ‘loop’ to be wired
with either fibre optic cabling or with inexpensive twisted-pair wire.
A single IQ System can have more than one IQ Loop. To function
properly, a IQ Loop must be unbroken.
Every IQ component needs a unique ‘address’ so that it can then
be individually controlled and monitored by the IQWin software
and can also coexist on the IQ Loop with other similar units.
An IQ address for the PS-8810 can be any number from 1 to 250.
Other IQ components can be set to addresses above 250, but do
not do so, because numbers above 250 are reserved for special
use. With the BSS PS-8810 address “0” (zero) disconnects external
communication.
To set the address:
1
Push and hold the front-panel RECALL button until the
display changes to 'Address select' mode, (i.e. “001”)
2 Press the UP or DOWN buttons to select the desired
address number.
3 Press the RECALL button again to store the address.
The display will automatically return to ‘Preset’ mode in a few
seconds.
No two IQ components of the same type which are connected to
the same IQ Loop can have the same address. Suppose, for
example, an IQ System has two IQ loops, 1 and 2, and a BSS PS-
8810 is to be installed into loop 1 and given an address of 114. No
other BSS PS-8810 can be given the same address in loop 1.
However, a BSS PS-8810 in loop 2 can have the address of 114,
and another type of IQ component can be given an address of 114
in loop 1. For example, both a Crown IQ-PIP-USP2 and a BSS PS-
8810 can both use the same address on the same loop.
The BSS PS-8810 can serve as an IQ interface between a host
computer and a single IQ Loop for other IQ components. This can
eliminate the need for an external IQ Interface (i.e. IQ INTII) in a
small system. The BSS PS-8810 connects directly to the host
computer via the DB9 RS232 serial connector.
