3.5 REAL TIME CLOCK (option)
The Real Time Clock is available as an option. Printing and adjustment of the clock are managed by a
series of control characters:
$12 Prints clock
$13 Sets clock
$14 RTCK transmission in serial
ESC T Enters the time in the print buffer
ESC D Enters the date in the print buffer
ESC U Enters the date (American-style) in the print buffer
How to adjust the clock using the keyboard
The time and date can be adjusted by using the PRINT and FEED keys on the front panel of the printer.
Setting procedure is as follows:
• hold down the FEED key and simultaneously press the PRINT key. The printer will print the time and
date with an arrow indicating a digit to be changed;
• each time the PRINT key is pressed, the digit by the arrow will increase and the updated version will
be printed;
• to select the next digit which requires adjusting press the FEED key again. On completion of each
operation, the printer will print the updated time and date, highlighting by means of an arrow the digit
currently being selected;
• to terminate setting, press PRINT and FEED at the same time, or run through all the parameters.
Lapsed time meter
By means of this function (option available with the 5.3 software release) implemented in the Real Time
Clock, the total operating hours of the printer can be memorized. It is managed by three control characters
(only if the RTCK is available):
ESC O Transmits in serial total operating hours.
ESC o Inserts total operating hours in the line buffer, thus enabling this to be printed in any string.
ESC M Zero-sets total operating hours.
For more information on the control characters which manage the clock, see paragraph 4.3.
