Description The hit command allows you to emulate vbtually any front panel panel control sequence. The
result of sending HI through H15 is the same as physically pressing the appropriate front panel
key. Sending H16 emulates tuning the Rotary Knob one detent position counterclockwise.
H17 is similar, but emulates turning the Rotary Knob one detent position dockwise.
Second functions of front panel keys are selected by first sending H3 (SHIFT). For example, to
zero correct the instient, send H3XHSX. This command stig emulates pressing SHIFT and
thenzERocHEcK.
Important consideration: To force a command sequence to emulate front panel actions, each H
command must be termina ted by an X. The previous example (H3XH5X; zero correction) dem-
onstrates this. H3H5X is executed as H5X.
Programming
Note
The H12 and H13 commands are invalid for the Model 486. Sending these commands to the
Model 4% will result in an illegal device-dependent command option (IDDCO) error.
