4.6.13 DISPLAY TEST
Spec: All LEDs and LED segments individually light.
Procedure:
Start the display test mode:
Send: DA DT CT 80 06 09 03 CS; Select test display mode.
Verify display lights all LEDs according to the test pat- tern. (See Section 4.9 for test pattern)
Stop the display test mode:
Send: DA DT CT 80 06 09 02 CS; Select test display mode.
4.6.14PUSHBUTTON TEST
Spec: Pushbuttons operational.
Procedure:
Use one of the following two methods to test the three front panel pushbuttons:
Method 1 (Manual Verification)
Hold in the “SEL” button and verify the
Use the “SEL” button to select the preset mode
Press the “∧ ” button and verify the preset display in- creases its number.
Press the “∨ ” button and verify the preset display de- creases its number.
Method 2 (Auto Verification)
Use the following IQ command to continually poll the switch status object:
Send: DA DT CT C1 05 0A CS; Return button status
Return String: DA DT AK CT C1 05 0C BTN CS
Press the “SEL” button and very the object returns $01. Press the “∧ ” button and verify the object returns $02. Press the “∨ ” button and verify the object returns $04.
4.6.15 REAL TIME CLOCK
Spec: The RTC can be set, can be read, keeps time, and power backup is operational.
Note: The real time clock Ucode object uses a
Example: For 3:34:14 PM on July 21,1999:
914,544,000 seconds | |
29 years / 4 = 8 leap year days= | 691,200 seconds |
July 1 = (31+28+31+30+31+30)= |
|
181 days = | 15,638,400 seconds |
21st = 21 days = | 1,814,400 seconds |
PM = 12 hours = | 43,200 seconds |
3:34:14 = | 12,854 seconds |
Time from 12:00 AM Jan. 1,1970= | 932,744,054 seconds |
932,744,054 converted to hex = $37988B76
$37988B76 broken into bytes, LSB first = $76 $8B $98 $37.
Note: The real time clock is powered from a 1 mF capacitor (C25) when the unit is unpowered. This capacitor must be charged above 2.2 volts for the real time clock to operate with- out unit power. Normal charging time is 14 minutes. To fast charge the capacitor short TP7 and TP8 for at least 4.2 min- utes. Remove jumper prior to a power cycle to prevent dis- charging the capacitor.
