IEEE-488 Programming
5-21
Programming notes
1. Table 5-13 lists the number of bytes that are transmitted for the various data formats.
2. Since the data is transmitted in continuous strings (without carriage returns or line feeds), you
must format the data for display or printing legibility.

Notes:
1. Carriage returns and line feeds are not sent. They are shown here to improve readability.
2. Spacing between columns is one ASCII space.

Notes:
1. In addition, each unit is identified with a 9-byte ASCII string.
2. This value depends on the number of closed crosspoints.
3. Maximum of five talks, depending on number of slaves in the system.
