7-SEGMENT display
1. When the power supply is initialized, the program codes appear.
• Examples of the program code: 17 89 A3 16
2. Then the tracking of COMM KIT will proceed as the following:
• Display in normal operation
– If the value of the register number 40011 is 0 or there is no signal, "A" and "0" appear on the first and
second segments for 1 second.
→ Displays “3” and “0” or “1” for 1 second. (A030 device’s 30-Dip S/W #2 is OFF, A031 device’s 31-Dip
S/W #2 is ON.)
– If the value of the register number 40011 is not 0, “A” is displayed on the first segment, and the
hundreds digit number of the register is displayed on the second segment for 1 second.
→ The tens digit number is displayed on the first segment, and the unit digit number is displayed on
the second segment for 1 second.
