Manufacturer:CHINFA Description:The asynchronous mode is used for communication withasynchronousterminalswhichmay communicate at 600,1200, or 2400 bit/s +1%, - 2.5% even though the modems output is limited to the nominal bit rate .01% in DPSK and QAM modes. When transmitting in this mode the serial data on the TXD input is passed through a rate converter which inserts or deletes stop bits in the serial bit stream in order to output a signal that is the nominal bit rate .01%. This signal is then routed to a data scrambler and into the analog modulator where quad-bit/di-bit encoding results in the output signal. Both the rate converter and scrambler can be bypassed for handshaking, and synchronous operation as selected. Received data is processed in a similar fashion except that the rate converter now acts to reinsert any deleted stop bits and output data to the terminal at no greater than the bit rate plus 1%. An incoming break signal (low through two characters) will be passed through without incorrectly inserting a stop bit. |
