Overview
The TSC-9902 LTC to Serial Converter is a high-quality signal conversion solution within the family of GearLite
compact, self-contained modular products. Supporting Linear Timecode Signal (LTC) to Serial conversion, the
TSC-9902 is the ideal converter for interpreting linear timecode and sending the timecode over a serial port to
another device, such as the Ross Video CrossOver Solo or Carbonite Black Solo Production Switcher.
The TSC-9902 provides a single DB-9 connector for 38,400 baud serial RS-422 communication, and one BNC
connector for LTC input. Note that the shell of the BNC connector is isolated from ground. Power, LTC Status, and
Serial Tx LEDs show activity status.
A universal power adapter and line cord, suitable for the country of use, is supplied with each module. Various
mounting options are included that enable a wide range of installation choices.
