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.
