Reference Notes:
If you are not familiar with programming you will probably gain more understanding of the program-
related portions of this appendix by first reviewing Appendix A, API Commands and Appendix D,
ChartScan Program Examples.
λHardware configuration for RS-232 and IEEE 488 are discussed in Chapter 3.
λConfiguration for Net232 Ethernet/RS-232 Converter is discussed in the Net232 User’s Guide,
part number 1037-0921.
