GPIB Data Lines Trigger Condition

From GPIB Analyzer

The GPIB data lines trigger condition can be entered as an ASCII value in the ASCII edit control, a hexadecimal value in the Hex edit control, or a binary value in the D8 to D1 spin controls. Note that the GPIB data trigger condition is replicated in all three representations: ASCII, hexadecimal, and binary. Note also that the D8 to D1 spin controls have the added feature of letting you select x or "don't care" values for particular GPIB data lines whose states are not relevant to the GPIB data trigger condition. For example, if you want to configure the GPIB data trigger so that any non-ASCII GPIB data causes a trigger, D8 should be set to 1 and D7, D6, D5, D4, D3, D2, and D1 should be set to x.
