CHAPTER 5: Command Descriptions
LOCAL Command
In the System Controller mode, the LOCAL command without optional addresses causes the 488 Controller
to unassert the Remote Enable line. This causes devices on the bus to return to manual operation. As the
Active Controller, with bus addresses specified, bus devices are placed in the local mode by the Go To Local
(GTL) bus command. If addresses are specified, the state of the Remote Enable line is not affected.
