It is a 20-column printer complete with mechanism case, power supply and interface electronics. Alphanumeric characters are formed in a 5 x 7 dot matrix that extends to 5 x 9 for lower case letters with descenders Printing may occur at speeds adjustable up to 1.6 lines/sec. The printer is designed to interface with a wide variety of instruments having BCD outputs without requiring any additional electronic circuitry. All features mentioned here are standard with different print formats selected by means of DlP-switch controls. The Model 820A will accept up to 8 digits of BCD data in either the Parallel BCD or the Serial BCD modes. signal levels are TTL and CMOS compatible and either logic polarity may be accommodated for the BCD inputs and most of the control signals. A character table is programmed into the microcomputer to give the user a wide selection of symbols to be printed in the three columns reserved for indicating the Units-of-Measurement. An internal 24-hour digital clock provides an optional printout of days hours and minutes on each line of data to produce a permanent record of the time at which each data measurement is made. Special symbols representing overload and alarm are printed whenever the associated input logic signals are true. THANK YOU AND GOOD LUCK !!!!.LISA...
