In the IEEE Peripheral (IEEE 488 to RS-232 converter) mode, SW1-7 enables
the interface to assert the SRQ IEEE bus interface line to indicate that it has
received the last switch selected serial terminator character from the serial
device.

3.8 Serial Interface
The interface converter has the ability to output signal levels that are
compatible with either RS-232 or RS-422. An internal DIP shorting plug
determines which electrical specification is chosen. If the interface is to be
connected to an IBM
compatible with either RS-232 or RS-422. An internal DIP shorting plug
determines which electrical specification is chosen. If the interface is to be
connected to an IBM
®
PC or compatible, the RS-232 level should be selected.
If it will be connected to a Macintosh
®
, the RS-422 level should be used. For
connection to other computers, refer to the manufacturer’s manual to
determine which levels are supported.
