HELP
–
You can press
[F1]
for Help on a selected or
highlighted field or control. You can also click the
[?]
button in the upper-right hand corner of the screen
and click to point to a field or control to get a Help
message pertaining to the item you pointed to.
Select the Input Filtering
…
You may select the level of digital filtering to apply to the input
channel as Low, Medium, High, or None (No digital filtering). The
respective I/O response times are indicated in parenthesis next to
your filter selection. Note that higher filter levels result in lower
average noise, but with slower I/O response times. Always set the
input filter as desired before calibrating an input.
Select the Output 1 and Output 2 Ranges
…
This unit has both DC voltage and DC current output terminals at
each output channel. Current Output Ranges are 0-20mA, 4-
20mA, and Disabled, and the current output will drive up to 525Ω.
Voltage Output Ranges are ±10V, ±5V, 0-10V, 0-5V, and Disabled,
and the voltage output may drive 1KΩ or higher loads. Only one
output, current or voltage may be loaded at one time.
Select the I/O Scaling…
You may rescale a selected input range differently for each output
channel and you could choose to use a smaller portion of the
nominal input range to drive an output if desired. Likewise, you
may rescale an output range. Be careful not to reduce an input or
output range too much, as resolution will be proportionally
diminished and noise/error magnified (each halving of range
reduces respective resolution by 1 bit).
In the Input Scaling fields for each output, set the input signal
minimum/zero value inside full range to correspond to the output
range zero value (over/under-range included). Set the input signal
maximum/full-scale value inside full range to correspond to the
output range full-scale value. You may also rescale the output
range similarly. You could optionally swap input levels to
configure a reverse acting output response if desired. Note that
some under and over-range is built into every I/O range selection
and these limits vary by range.
If the scaled input/output zero and full-scale points are chosen too
close together, performance will be degraded.
Once you have made your configuration selections, click the
[Send
I/O Config]
button to write them to the module. You can read the
Status of your sent message to the unit in the “Status” field.
Alternately, you could click
“

in the upper left corner to save
the settings to a file on your PC, for later reference.
