2.4.2 IEEE Bus Terminator Selection
SW3-6 through SW3-8 set the IEEE bus terminators used for data sent
or received by the Serial488A. EOI, a line used to signal the end of a
multiple character bus transfer, may also be enabled. If enabled, EOI is
asserted when the last selected bus terminator is sent. Factory default is LF
Only with EOI disabled.

2.5 Mode Selection
SW2-1 sets the major operating mode of the Serial488A. The IEEE Controller
(RS-232 to IEEE Converter) mode allows a serial host device to send data to a single
IEEE bus peripheral. Applications include interfacing a listen-only or addressable
IEEE printer/plotter to a serial printer port. Refer to Section 3 for more detailed
information on the controller mode of operation.
