IEEE 488 interface test
19. This section verifies IEEE 488 operation.
(1) Ensure that the IEEE 488 address of the ADTS 405 is set to 1 as follows:
a. Hold down F1 and press SETUP to display the CONFIG menu.
b. Select [MORE], [DISPLAYS/OPTIONS], [OPTIONS], [IEEE 488],
[DEVICE ADDRESS]. Enter an address of 1 by pressing 1 then ENTER.
c. Press QUIT.
(2) Switch off the unit and pumps.
(3) Connect the PC with IEEE 488 interface to the IEEE 488 connector under the cover
on the front panel.
(4) Switch on the unit. Wait until the display shows altitude and airspeed.
(5) Run the test program on the PC.
(6) Check that “REMOTE” appears in the lower right corner of the display.
(7) Check that “PASSED” is displayed on the PC.
(8) Switch off the unit and disconnect the PC and IEEE 488 cable.
IEEE 488 test program
20. The following test program should be implemented on an IBM PC or compatible computer.
The test program is shown in pseudo code. The exact details of the commands depend on the actual
IEEE 488 interface card used and the language used for programming.
(1) Definitions
string1 = “SOURCE:STATE OFF” (one space between STATE and OFF)
string2 = “SOURCE:STATE?” (one space between STATE and OFF)
(2) Program
Open channels to the IEEE 488 interface card for control and data.
Set up interface as:
Device address = 1
Time out 5 secs or greater.
EOI with last byte out.
Input terminated by EOI
Send Interface Clear.
Send string1 to device 1.
Send string2 to device 1.
Instruct device 1 to TALK and input the response string.
IF device time-out THEN
Display “FAILED - TIME-OUT”
STOP
ENDIF
IF response string = “OFF”
THEN
Display “PASSED”
ELSE
Display “FAILED”
ENDIF
End of IEEE 488 test program.
