Addressing the Module

The examples shown in this chapter use the default addresses for the

interface, Command module, and Digital I/O module. The address uses both

GPIB primary and secondary addresses. The default address is:

To establish these defaults as an I/O path in BASIC, the program examples

use this code:

10 ASSIGN @Dio TO 70918

Each Digital I/O module in a system must have a different logical address.

Additionally, no two instruments in the same system can have the same

logical address. Setting the logical address is described in Chapter 2 —

“Configuring the Agilent E1330B Digital I/O Module”.
