The LTC 8561 Series, LTC 8564/20, and LTC 8566 Series
On-site Receiver/Drivers are control data decoder units
and motor drivers for pan/tilt units and zoom lenses.
These receiver/drivers are used in conjunction with
Allegiant
®
Series Microprocessor-based Switcher/
Controller Systems.
The receiver/driver decodes Allegiant Bi-Phase control
data from the switcher/controller system through the
LTC 8568/00 Signal Distribution Units into specific control
codes. In addition, the receiver/driver will accept RS-232
control code data generated by the LTC 8780 Series Data
Converter Unit.
These receiver/drivers are available in a variety of input
and output voltage configurations. All units are 50/60 Hz
line frequency compatible. All units have low voltage DC
lens drivers (6 volts or 12 volts selectable) for focus,
zoom, and iris with adjustable speed. There are also four
auxiliary outputs. One is a solid state relay with zero
crossing switching fixed to the same voltage as the pan/
tilt output. The others are relays which can supply voltage
through contacts (normally open or normally closed) to
control lights or other devices at the remote site. Auxiliary
supply terminals provide power which is fuse-protected at
the voltage of the pan/tilt output.
Advanced features include 99 pre-positions when using
conventional 355° pan/tilt drivers, 82 pre-positions when
using 360° continuous pan/tilt drivers, installer friendly
connectors, lockable enclosure latches, 10-bit resolution
for improved pan/tilt pre-position accuracy, and automatic
pre-position tour capability.
Additional features include a full operating temperature
range, an integral local test function, an unrestricted auto-
pan feature for all models of pan/tilts, random pan, a
unique dither feature, selectable latching or momentary
auxiliaries, polarity reversible lens drive, convenient
thumbwheel selectable camera addressing, and a
NEMA-4X, IP66 rated environmental enclosure.
