4.1.3 Communication Protocol
The Model 414A has a real time clock and enables the time and date to be set
and printed on tickets. The date format can be European (days/months/years) or
USA (months/days/years), while the time is on a 24 hour clock.
Note that the clock will only retain its time for 3 days minimum if there is no
power connected to the instrument. After this period, the clock may need to be
reset.
The baudrate, parity and word length can be programmed during calibration and
the user must ensure that these correspond to the setting on the printer or
computer with which the 414 is communicating.
The software protocols can be selected during Calibration to provide standard
interfaces to a number of printers and computers. Since other interfaces will
continue to be added, the user should consult the manual "The RS232/422/485
Communications Option for the 400 Series, Version 2", for the latest protocols
and printer drivers.
