Setting the Logical Address Switch
Figure 1-4 shows the logical address switch location and setting. The logical
address switch factory setting is 72. Valid addresses range from 1 to 255.
When used with an HP Command Module the factory set address of
decimal 72 results in a module address of 9 (72 divided by 8). The module
address is used as a secondary address when using HP-IB and a Command
Module. For example, the module address may be 7 09 09, where 7 is the
HP-IB interface address, 09 is the command module address, and 09 is the
HP E1418A address.
The HP E1418A supports dynamic address configuration. When you set the
logical address to 255, the resource manager sets the logical address
programmatically.
Note When using an HP C-size mainframe with the HP E1405/E1406 Command
Modules, the logical address setting must be a multiple of 8.
