IQ-USM 810
Reference Manual
5.2 Specifications
General
Front Panel Controls:
Front-panel switches select
IQ Address, Baud Rate, 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:
IQ 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, Buchanan
®
type cable connector or equiva-
lent 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-segment digi-
tal display indicates the IQ-USM 810's initialization se-
quence 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, 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.
