Dynamic addressing
3.5.1
In models with dynamic addressing support you
can connect a number of
units in series, allowing control of multiple attenuators from a single USB or Ethernet port, with
each attenuator controlled independently. Dynamic addressing sets the addresses automatically
in the order the attenuators are connected (no need to set addresses for each unit) with the
master unit (unit connected directly to USB or Ethernet control) as address 0 and the slave units
incrementing to the end of the chain.
3.5.2
The additional “Dynamic Address” panel on the
right-hand side of the
main control screen will appear if any slave units are detected when the GUI connection (USB
or Ethernet) is initiated. This panel shows the number of units connected and their current
attenuation settings. If any changes are subsequently made to the daisy-chain interconnections
the “Refresh” button can be used to have the addresses checked and re-assign automatically to
all units in the chain.
