The Multifunction Module
The multifunction module (34907A) adds two additional measurement
input capabilities to the system: digital input and event totalize.
The multifunction module also contains a dual voltage output (DAC)
which is described in more detail on page 68.
Digital Input The multifunction module has two non-isolated 8-bit
input/output ports which you can use for reading digital patterns. You
can read the live status of the bits on the port or you can configure
a scan to include a digital read. Each port has a separate channel
number on the module and contains 8-bits. You can combine the two
ports to read a 16-bit word.
