LTC 8780 Series Data
Converter Units
Features
▶
Designed for various applications utilizing Allegiant
Series Switchers
▶
Converts Allegiant Bi-Phase control code to RS-232
and RS-232 to Bi-Phase
▶
Provides satellite address decoding
▶
Signal distribution mode provides 15 separate
outputs
The LTC 8780 Series are accessory units that convert the
Allegiant system's Bi-Phase control code into RS-232, or
convert RS-232 back to Bi-Phase code. They provide the
capability of transmitting the control code over
conventional RS-232 transmission mediums such as
phone modems, fiber optics, microwaves, etc.
The unit accepts the Bi-Phase control code generated by
an Allegiant main CPU bay, Bosch Series DVRs, Signal
Distribution units, and LTC 8569 Series Code Merger
units.
The LTC 8780 Series are also designed to perform the
Satellite selector functions in an Allegiant satellite system
configuration. In addition, using its integral signal
distribution capability, the LTC 8780 Series can function
as remote distribution units for driving up to 120 receiver/
driver devices connected to its 15 outputs. As a
distribution unit, wiring can be in either a star or daisy
chain configuration, and each output is capable of driving
eight (8) daisy chained receiver/driver loads, at up to
1.5 km (5000 ft) away using 1 mm
2
(18 AWG) shielded
twisted pair (Belden 8760 or equivalent).
