Analog outputs of the MX878B
The MX878B is a dedicated module designed for analog
outputs and math channels. In contrast to other modules,
the MX878B has no analog sensor inputs. Instead it
receives data from other modules via the
”
isochronous
IEEE1394b FireWire transfer
”
. The module then routes
this data to an analog output.
You need to connect all modules via IEEE1394b
FireWire (or use a backplane) for the MX878B to become
operational! Please note the

”
column in the cat­
man® channel configuration window. This column indi­
cates if a channel provides its data via the isochronous
link (indicated by a symbol). Click the column or use the
column
’
s context menu to enable or disable isochronous
transfer for a channel.
Providing the data via isochronous transfer may use up
significant computing power on the module (in particular
on the MX410B module and the MX460B high-speed
module). Do not activate the isochronous data transfer
unless it is actually needed!
