TC8780 Series Data Converter Units

The TC8780 Series convert the biphase control code
generated by Allegiant series matrix switchers and
the TC8135 Series controller/followers into standard
RS-232, and converts RS-232 back to biphase code.
This provides the capability of transmitting the
biphase control code over conventional RS-232
transmission media (phone modems, fiber optics,
microwaves, etc.) The TC8780 can also be used to
perform the Satellite Selector functions in Allegiant
satellite system configurations and operate as a 15-
channel remote signal distribution unit.
TC8781 Series Time/Data
Converters
The TC8781 Series are accessory units that decode
the Allegiant system's encoded time/date information
generated on the biphase control code line and
convert it into an RS-422 format using the GPS
format. This time/date information can be used to
interface into external time/date inserter products
(such as the Kalatel KTS-53-16), which are designed
to be synchronized via a GPS signal. The electrical
and mechanical specifications are the same as the
TC8780 Series units.

TC8785 Series Code Converters

TC8785 Series units are designed for use in existing
Allegiant systems which have been upgraded to
operate the new AutoDome series of cameras. The
TC8785 Code Converters are used to provide the
source for the "fixed speed" control code when the
system is generating the new "variable speed"
control code preferred by the AutoDome cameras.
The TC8785 Series Code Converter receives the
"variable speed" control code from the Allegiant via
its TC8568 Signal Distribution unit and converts it
into the appropriate "fixed speed" control code.
Outputs from the TC8785 Series Code Converter
may be connected
receiver/drivers using existing field cables.
