SCXI-1120D NI Controller module Brand new
In the parallel-output mode, the counter is disabled and amplifier channel 0
is selected at the output multiplexer and is connected to MCH0. The seven
other channels are hardwired to MCH1 through MCH7 on the rear
connector.
The output multiplexer multiplexes all eight amplifier outputs and the
temperature-sensor reading provided on the MTEMP line. This
measurement is only software controlled. For hardware control of the
temperature sensor reading, connect the temperature sensor to pin 18 on the
rear connector as described in Chapter 2, Configuration and Installation.
The multiplexer output connects to the MCH0± and is connected to the
DAQ device analog channel input. In the case of the MIO DAQ devices,
MCH0± on the rear connector corresponds to ACH0 and ACH8.
Notice that when the multiplexed-output mode is selected, pins 5
through 18 on the rear connector are still driven by the SCXI-1120/D. The
SCXI-1120/D outputs on the rear connector are short-circuit protected.
Parallel Mode
When the MCH0 signal is configured to be the output of channel 0, the rear
connector simultaneously carries each of the outputs of the SCXI-1120/D
on different pins, and the module is in parallel mode. In this mode you can
use an SCXI-1180 feedthrough panel to make each of the outputs available
at the front of the chassis. A DAQ device cabled to an SCXI-1120/D in
parallel mode reads a separate output signal from the module on each of its
analog inputs. You cannot multiplex the parallel outputs of a module onto
the SCXIbus; only a DAQ device directly cabled to the module has access
to the outputs.
Multiplexed Mode (Recommended)
In multiplexed mode, the output signals for channels 1 through 7 are sent
to the rear connector but are usually ignored. All reads from the module are
from the MCH0 signal of the rear connector, which can be configured as
the output of any channel of the SCXI-1120/D or as the output of any other
module in multiplexed mode that is sending its output onto the SCXIbus.
You can also configure the SCXI-1120/D to send any one of its outputs to
the SCXIbus. Thus, in multiplexed mode only, one module in a chassis
needs to be connected to a DAQ device; you can pass signals from the other
modules to the DAQ device through the SCXIbus.
