RS-232↔IEEE 488 INTERFACE CONVERTER

4.5 Plotter Applications

To use the interface converter to interface an HP-IB plotter to a serial computer port, you will need the following information about your system:

1)The serial data format that the application (plotting or graphics) program expects the plotter to communicate with. These parameters include baud rate, word length, stop bits, parity and serial control.

Some programs allow these parameters to be selected by the user. Other graphics programs depend on the RS-232 version of the plotter defaults. Usually, Hewlett-Packard plotters use 9600 baud, 7 data bits, 1 stop bit, even parity, and X-ON/X-OFF serial control. Since these plotters are available with serial interfaces, the operator’s manual of your IEEE plotter should contain this information.

2)The IEEE bus address of your plotter. This address is usually set by a DIP switch located on the rear of the plotter. The first five switches set the address, which, for Hewlett-Packard plotters, is usually address 5. Refer to the plotter’s operator’s manual for exact information.

Set the interface converter’s internal DIP switches to match the parameters determined above. Other parameters which should be selected include:

1.Talk-Back on Terminator Enabled.

2.Talk-Back on Timeout Enabled.

3.Serial Terminators set to CR Only.

4.IEEE Terminators set to CR Only with EOI enabled.
