Appendix G
Setting Switches
This appendix explains how to set the configuration switch of the
GPIB-232CT when operating in S mode.
As shown in Chapter 3, switch 1 is placed down (or off) to operate in S
mode. Set the remaining switches to match the characteristics of the
terminal or computer you will attach to the other end of the serial cable.
Often, you can change the serial port characteristics of the terminal or
computer by setting switches, running a utility program, or from within
BASIC. Determine the default characteristics of your computer or
terminal's serial port. If you want to change the configuration on that side,
do so before attempting to communicate with the GPIB-232CT. Then, set
the configuration switch on the GPIB-232CT to match your serial port
characteristics.
For example, for Microsoft BASIC on a Macintosh, the default
characteristics are as follows:
• baud
rate:
300
• parity: even
• data
bits:
7
• stop
bits:
1
If these defaults meet your needs, set the switches on the GPIB-232CT as
shown in Figure G-1.
