Description

The LTC 8780 Series are data converter units that are designed to operate with the Allegiant®
Series of video matrix switcher/controllers or other controller devices that generate biphase
control code. The LTC 8780 Series converts the biphase control code, generated by the Alle-
giant system into standard RS-232 and converts RS-232 back to biphase code. This provides
transmission of the biphase control code over conventional RS-232 transmission media
(phone modems, fiber optics, microwaves, etc.). In addition to operating as a 15 channel
remote signal distribution unit, the LTC 8780 Series can also be used to perform the Satellite
Selector functions in Allegiant Satellite system configurations. A conceptional operational
block diagram is shown in Figure 2.1 on page 2, and may be used for reference purposes.
