RS-232↔IEEE 488 INTERFACE CONVERTER
Figure 4-6. Interface Converter Settings for Use with HP 7580A Plotter
on an IBM PC.
When using the interface converter with plotting programs on the Macintosh
computer with graphic drivers such as MacPlot
®
, some serial data format
parameters are user-modifiable. The following is a partial MacPlot config-
uration screen which allows selection of baud rate, stop bits, and parity. With
this driver, the word length is fixed to 7 data bits with X-ON/X-OFF serial
control. These non-modifiable defaults are plotter dependent. Refer
to the plotter or driver manual for the defaults of the specific plotter.
For this example, 57600 baud with one stop bit and no parity has been
chosen for the serial data format.
