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”.
