It is not possible to transmit data from the computer to the terminal and terminal to computer simultaneously. A computer may communicate with a terminal in this mode.
In this mode, data transmission may take place in either direction, but at a time data may be transmitted only in one direction. In duplex mode, data may be transferred between two transreceivers in both directions simultaneously. For example, the processor may transmit data for a CRT display unit in this mode. 8.2.1 Basic Modes of data transmissionĭata is transmitted only in one direction over a single communication channel. It is also able to receive a serial stream of bits and convert it into parallel data bytes to be read by a microprocessor. This chip converts the parallel data into a serial stream of bits suitable for serial transmission. Interface, refer to the MAX504/MAX515 data sheet.8251 is a Universal Synchronous and Asynchronous Receiver and Transmitter compatible with Intel’s processors. For DACs with similar features but with a serial data For a hardware and software compatible 12-bit upgrade, refer to the MAX530 data Inputs are double buffered and are compatible with 4-bit, 8bit, and 16-bit microprocessors. The use of external resistors or op amps.
