General
Front Panel Controls:
Front-panel switches select IQ
Address, Baud Rate, factory default preset (P00), and
any of 32 user-defined presets (P01–P32).
Rear-Panel Controls:
A 3-position selector switch
(mic/line/phantom) and a calibrated gain control for
each input.
Connectors:
Crown Bus: RJ-45 for input/output, RJ-45
for daisy output, RS232: DB9F computer interface for
both component and interface modes. Multi-function
Port: DB37M for analog inputs, digital inputs, digital
outputs, +5VDC, +10VDC and Ground. Audio Inputs
and Outputs: 3-pin male removable barrier block con-
nectors, Euro-style cable connector supplied. AC
Power: IEC320 connector for AC power cord.
Display :
A blue front-panel Enable indicator lights to
show that the unit is plugged in and AC power is being
supplied. An amber front-panel Data Signal Presence
Indicator (DATA) flashes whenever commands ad-
dressed to the IQ-USM 810 are received. A green
front-panel Interface indicator lights when the IQ-USM
810 is being used as system interface. A three-digit
digital display indicates the IQ-USM 810’s initialization
sequence by displaying each processor’s name as it
comes online, indicates the presently selected preset,
indicates the IQ address and baud rate while those
parameters are being adjusted, indicates when a pa-
rameter has been stored in flash memory, and when
any parameter is varied from its value within the cur-
rently selected preset. Ladder Display: A front panel,
sixteen-segment LED display matrix can be set to
three different operating modes: Level Meter, Input
Gate Status, and Infinity Pattern.
Power Requirements:
100VAC to 240VAC, 35VA
nominal.
Protection:
if communication is lost, the unit will con-
tinue to function with the last commands received.
