• Line 1: Initial command prompt from the Keyboard Controller program.
• Line 2: Instruct the Digital488/80A to turn on its TEST LED indicator. The TEST LED indicator
should light up.
• Line 3: Instruct the Digital488/80A to turn off its TEST LED indicator. The TEST LED indicator
should turn off.
• Line 4: Reset the Digital488/80A.
• Line 5: Retrieve the Channel 0 status (IEEE 488 bus address 08).
• Line 6: The status message shows that all default options are in use.
• Line 7: Retrieve the Channel 1 status (IEEE 488 bus address 09).
• Line 8: The status message shows that all default options are in use.
• Line 9: Retrieve the status of the port configuration mode for Channel 0.
• Line 10: The status message shows that the default port configuration
C0 is in use.
• Line 11: Program all the Channel 0 Ports as outputs.
• Line 12: Retrieve the status of the port configuration mode for Channel 0.
• Line 13: The status message shows that the Configuration (
C ) command C5 was executed.
• Line 14: Retrieve the status of the port configuration mode for Channel 1.
• Line 15: The status message shows that the default port configuration
C0 is in use.
• Line 16: Program the Digital488/80A Channel 0 to send output data when addressed to Talk.
• Line 17: Send the data 123 to Channel 0.
• Line 18: Read the data from Channel 0. The message shows the data 123.
• Line 19: Program the Digital488/80A to set Bit 37 on Channel 0.
• Line 20: Read the data from Channel 0. The message shows that Bit 37 is set, and also the previous
data 123.
The above examples may also be repeated using Secondary addressing mode. To do this, turn off the
Digital488/80A, and set the rear-panel DIP switch S1 for Secondary addressing mode. Then repeat the
above commands, substituting IEEE 488 bus address 0800 for 08, and address 0801 for 09, in all of the
commands.
