7 Bit Transmitter

This document describes the 4709 7-bit Transmitter, a parallel-to-serial converter contained on a double-length DEC System Module board. The module handles parallel-to-serial conversion, buffering, and synchronization between parallel devices and asynchronous serial lines. Key features include a jumperable Stop Element Counter (supporting 1.0, 1.5, or 2.0 units), dual complementary output terminals, and a flag indicator for external device synchronization. The manual includes technical specifications for inputs/outputs, power requirements, and instructions for configuring internal jumpers.
