For DIO1 to DIO6, the status byte format is identical to that used for the GP-IB
interface. For details, refer to page App-12.
Note
•
After the status byte responds to the serial poll from the controller, this bit is reset to 0. Until
the serial poll is responded to, each interrupt is stored, and if more interrupts occur thereafter,
they are added.
• To prevent the status byte being affected by a computation END, syntax ERROR, or OVER,
use the "IM" command to set a value with the corresponding bits set to 0.
Each data consists of a 4-byte header and 8 bytes of data.
You can specify whether a header is output using the H command.
