RS-232↔IEEE 488 INTERFACE CONVERTER

5.7 IEEE Address Selection

SW3-1 through SW3-5 select the IEEE bus address of the interface converter when in the IEEE Peripheral mode. The address is selected by simple binary weighting with SW3-1 being the least significant bit and SW3-5 the most significant. The following figure shows the IEEE address of the interface converter set to 10.

Listen Only Mode

Listen Only is a special type of Peripheral operation. In the Listen Only Mode the interface converter accepts all data transmitted on the bus and transfers it out its serial port. The interface converter is set to Listen Only mode by setting its address to 31 (switches SW3-1 through SW3-5 all open).

NOTE

The 232-488 Converter does not support all of these functions. Refer back to controller mode (Section 4.1) and peripheral mode (Section 5.1) for more information about operation of this particular device.
