Whenever the 8842A is in the local state, the IEEE-488 address can be displayed on the
front panel by pressing the LOCAL button.

3-4. AN OVERVIEW OF REMOTE OPERATION

An overview of remote operation is presented in the block diagram in Figure 3-2. Each
block represents a register, buffer, etc., contained in the 8842A. The status registers in the
center column indicate the instrument's status, including its function, range, reading rate,
etc. The input buffer receives data from the IEEE-488 bus. The output buffer receives
data from the blocks to its left, and sends data on to the IEEE-488 bus.
