Chassis Synchronization and Triggering Features and Functions
Asynchronous flagging is accomplished by sending a flag and having the rest of
the system act in a pre-configured way when it receives the flag. Any flag can be
set or cleared (by assigning a static 1 or 0) or sourced, using the Web Interface.
The Flag lines are bidirectional. Any chassis can enable any of the four Flag lines
as a trigger bus destination or specify a Flag as a trigger bus source; the
MultiFrame logic will only allow one source per Flag in the MultiFrame.
Use When: The MultiFrame Flags provide for module to module signaling
between modules in different chassis.
To use a MultiFrame Flag as an output signal:
1
As you can see below, there are no Output Enable check boxes; the
MultiFrame output signals are always enabled.
2
From the
Input Signal
drop down list, select the input signal for each
MultiFrame Flag output signal.
In the above example, Flag 1 will output a trigger when an input signal is
received from an instrument on the TRIG 0 bus. Flag 2 will output a trigger when
an input signal is received from an instrument on the TRIG 1 bus.
Separately, you will need to program other chassis how to respond to a received
MultiFrame flag.
MultiFrame SYNC
A SYNC line is provided on the MultiFrame cables. This can be used to
synchronously trigger any AXIe instruments in the MultiFrame.
To use MultiFrame SYNC as a Trigger Output
A SYNC signal output from the master chassis in the MultiFrame will be passed
to the other chassis over the MultiFrame cable, as MultiFrame Sync.
