18 Configuring the RF Multiplexers
Chapter 2
Setting the Address Switch
The logical address switch (LADDR) factory setting is 120. You may have
changed the setting during module installation. Valid address values are
from 0 to 255. If the RF Multiplexer is used with a command module in a
C-Size mainframe, see the command module user’s guide for addressing
information. Otherwise, see Figure 2-1 to change the setting.
NOTE
The address switch selected value must be a multiple of 8 if the module is
the first module in a “switchbox” used in a VXI mainframe, and is being
instructed by SCPI commands.
