EATURES
In the IEEE Controller (RS-232-to-IEEE 488 Converter) mode, SW1-7 is
used to determine whether the interface should, after sending the IEEE
bus terminators, address the attached bus device to talk. The factory default
is Talk-Back On Terminator enabled.
SW2-2 selects whether the interface converter should address the attached bus
device to talk when the interface converter has nothing more to send to that
device. The factory default is Talk-Back On Timeout enabled.
Refer to Chapter 4 for complete details on these features.
