NTP 297-3601-316 08.01 August 2006For Generic 602.202-53 Switch settings for printed circuit packs• SDI port assigned to TTY (terminal equipment or terminal program):- OUTPUT: the highest order bit (8) is forced in software to space (0).The remaining seven bits represent the ASCII character. Thus, theconfiguration settings of the terminal or terminal program should be:7 bits data, space parity, and 1 stop bit.Alternatively, a terminal setup of 7 bits, mark parity, and 1 stop bit can be used ifthe terminal ignores parity. Consult an operator's manual for the terminal orprogram if necessary. The SDI does not support an extended ASCII character seton devices capable of displaying extended ASCII when the eighth bit is set tomark (for example, interfacing to DOS-compatible PCs or terminal programs).- INPUT: eight bits are input and echoed; the highest order bit isignored by software. This does not affect terminal settings.• SDI port assigned for applications that use an eight-bit data stream (that is,MDR, SCCS, SMDI). These applications are non-ASCII based and theequipment outputs and inputs 8 data bits.- OUTPUT: all eight bits are transmitted.- INPUT: all eight bits are received and processed.Note: At baud rates above 1200, caution should be used wheninterfacing with equipment other than man-machine interface equipment.The rate of data transfer associated with machine-machine interfaces canexceed the buffer capacity of the I/O system, which can result in loss ofdata.
