Page 17: Afg Logical Address
The AFG is shipped from the factory with a logical address setting of 80, as shown in Figure 1-1. Address The E1340A AFG logical address is used: to place the AFG in the servant area of a commander (e.g. HP E1405/E1406 Command Module).
Page 18: Addressing The Afg
B-size and C-size systems under IBASIC control. Primary HP-IB Address (09): This is the address of the HP-IB port on the Mainframe or Command Module. Valid addresses are 0 to 30. The mainframe/command module has a factory set address of 9.
