4.5 Output channels
4.5.1 Analog output channels (MX878B)
The MX878B Analog Output Module generates analog output signals in the range of
+/-10 V. The source input channels are limited to FireWire connected MX modules.
Configure analog outputs on the
NOTE
The support for the MX878B analog outputs is limited to an "analog follower"
mode where the output simply follows the input channel. There are very limited
options for using digital filters.
Source channel: Select the desired source MXB input channel from the list of
available channels. The Range Min/Max parameter values must be defined for the
input channel. The MX878B channel output is scaled so that -10V is output at the
Range Min setting and +10V is output at the Range Max setting.
Source signal: The MX modules can generate two signals (that is, two data
streams) for each channel. Signal 1 refers to the signal generated using the input
channel parameterization. Signal 2 uses the same parameterization, with the
following exceptions.
The sample rate is set to the highest value available for Signal 2 data streams

(that is, 2500 S/s in Decimal sample rate domain and nominal 2400 S/s in
Classic sample rate domain).
No digital filter is used.

4.5.2 Digital output channels
Digital outputs are the sink channels on a CX23-R DIO connector. Configure digital
outputs on the

CX23-R DIO specific configuration
Input channel: Select the desired input channel from the list of available logical
channels.
Output mode: Select the desired output mode from the following options.
The terms "Set sink" and "Clear sink" relate to closing and opening the switch that
allows current to flow to ground or not. For example, an LED will illuminate when
the input channel is logic TRUE (i.e., channel value is 1) when a "Set sink" option
is used. Use the "Clear sink" to invert this control logic.
Select one of the "latched" options to have the output stay in the same state after
