Purpose.
Commands some or all devices to return to front
__________
panel control.
The LOCAL command is a very flexible way to command
one or more devices to respond to their front panel, local,
controls rather than to the PSI BOX.
If no device address is specified then the PSI BOX drops
both REN and ATN lines false, ALL IEEE bus devices are now
under front panel control. If one or more devices addresses are
given then those devices are commanded to Listen and then told
via the GTL command to respond to their front panel controls
rather than to the PSI BOX controller.
