Large Digit Display

The large digit display has a 4 or 8 digit 7-segment display that typically displays the time and temperature but may display any user message.  The setup menu may only be accessed through the RS232 serial port connected to a standard terminal program such as telix, terminal or hyper terminal.  The communication parameters are: 19200, 8 databits, one stopbit and no flow control.

When the Enter key is pressed the main menu will be displayed as shown below:
SRI Large Digit display
  V1.01
*** Main Menu ***
A. Real-time clock  10:36:25  12/03/01
B. Display
C. Temperature  20.00

Pressing the relevant letter A-C on the keyboard may access each function.  Note that these letters are not case-sensitive, so 'a' and 'A' will both access the same function.

  1. REAL-TIME CLOCK

Select this function to set the real-time clock.  Enter the time first as hh (24 hour time). The computer will then display a ':' and the minutes may be entered as mm - the computer will write a ':' and the seconds may be entered as ss.


The day, month and year may be entered in a similar way, but each field must be entered as two digits - JAN is not acceptable in the month field and 2001 should be entered as 01.

2. DISPLAY

Eight characters may be entered using the "B. Display"
