This option is used for repetitive output of the very same data
buffer on port B.
Note: When no more than 8192 values are to be output for an in-
definitely long period, this is done on firmware level of the ME-5810
without loading the host computer.
4.2.1.4 External Trigger
On the „S“-versions the trigger conditions for starting and stop-
ping the streaming operation mode can be selected very flexibly. It
is thus possible to enable one or more trigger inputs individually,
with specification of the desired trigger edge (rising, falling, or
any). All the enabled trigger inputs are logically ORed together. This
means that the first edge to arrive that meets the trigger condi-
tion starts or stops the input/output operation, according to the
selected operation mode (stream timer or stream trigger sample).
In other words, any change of the bit-pattern can be used as a
trigger event for the subdevice concerned.
For subdevice 0 all inputs of port A (DI_Ax) can be used and for
subdevice 1 all outputs of port B (DO_Bx) can be used, as they can
be read back (see picture 19).
