1. Introduction
================
DAQami is an out-of-the-box data acquisition software companion for
acquiring, viewing, logging, and generating analog/temperature, digital, and
counter data with supported Measurement Computing data acquisition devices.
Configure the device and the channels to use as the data source,
run an acquisition, and view the data on any combination of Scalar,
Strip, and Block displays. Data from selected channels can be logged to TDMS files
for later review, and can be exported to a .csv file for further analysis. You can
also save your device, channel, sample rate, trigger, and display settings
to a configuration file for later reuse.
=======================
2. Installation
=======================
IMPORTANT: Install DAQami before connecting your supported MCC DAQ
device.
The DAQami installation includes a self-extracting installer file,
DAQami.exe.
=======================
3. Getting Started
=======================
Once you install the DAQami software, connect your device and let
the driver files load. After the drivers are loaded, launch DAQami.
=============================

6. Known Issues
=========================================
-------------
Analog Output
-------------
|579129|
If there is at least one activated hardware-paced analog output channel,
changing the slider control for another analog output channel causes a glitch
in all other AO channels (both hardware and software-paced).
There is currently no known work-around for this issue.
–––––––––––––
Configuration
––––––––––––-
|473375|
Some supported devices require some configuration options to be set
with InstaCal:
* E-1608, E-DIO24, E-TC, TC-32: configure the connection code, alarms, and manual
network settings (IP address and so on) with InstaCal before running DAQami.
DAQami can communicate with any device whose connection code is set
to "0" in InstaCal, regardless of the code entered in DAQami.
* USB-TEMP, USB-TEMP-AI, USB-5203: Configure RTD, thermistor, and
semiconductor measurements with InstaCal before running DAQami.
|612016|
Auto Configuration locks up when using a USB-TC-AI for the first time.
When adding a USB-TEMP-AI using an Auto Configuration for the first time
after running DAQami, the configuration locks up.
Workaround: Close DAQami, disconnect and reconnect the USB cable on the USB-TEMP-AI,
and re-launch DAQami.
–––––-------
Data Logging
–––––-------
|405216|
DAQami does not check the amount of disk space available during
acquisition.
Workaround: Before you run an acquisition involving a large number
of samples, check to make sure you have enough disk space.
–––––––––––––
Execution
––––––––––––-
|621259|
If a DAQami acquisition is stopped by opening another MCC application -- such as Instacal,
a Universal Library-based application, or TracerDAQ(R) -- DAQami does not notify the user
that the acquisition has stopped.
If one of these applications is started during an acquisition and then closed, the DAQami
acquisition stops, but there is no error and the status remains running.
Workaround: Save the configuration, close DAQami and the other application, and then
re-launch DAQami and run the acquisition again.
-----------------------------------
Concurrent Input and Output Scans
-----------------------------------
|611365|
Devices configured for input scan and another for output scan
results in delayed output signal at 1 kS/s and below.
If one device is configured for an input scan and another for an output scan,
no output signal is evident at the beginning of the acquisition. For input scans running
at 1 kS/s, the output does not begin to change until about 15 ms to 70 ms (it varies from
scan to scan. Output scans were configured for single channel and 1 Hz waveform.
This also occurs with a single device installed and scanning both input and output.
–––––––-
Hardware
–––––––-
|480626|
miniLAB 1008 can only use DIO0 as trigger channel regardless of
the InstaCal setting.
Workaround: Selecting a trigger source other than DIO0 in InstaCal
is ignored in DAQami.
-------------------
Hardware Triggering
-------------------
|611738|
A hardware trigger using two devices is sometimes off by 25 ms to 75 ms between devices
running at 1 kHz. With the Start Trigger set to Edge and the Stop Trigger set between 100 samples
to 1000 samples on one device, the trigger signal is off by up to 75 ms scanning one channel on
each device. This usually (but not always) happens on the scan after changing the sample count used
for the stop trigger.

7. Fixed Issues
=============================
Version 4.2.0
|636424| Cannot open a configuration file saved with both a USB-CTR Series and
a USB-2416 Series device.
Configurations files saved with a USB-CTR Series and a USB-2416 Series device can now
be opened in DAQami.
Version 4.0.0
|381519| Overlapping cursor values can be read by zooming in on the display.
|387230| Slow performance is common immediately after a host PC returns
from hibernate/sleep mode. Refer to your PC documentation and support
resources to learn how to minimize this behavior.
|401042| Data on a Strip display now scrolls as cursors are moved left or right
off the edge of the chart. Cursors can no longer be moved beyond the left or right
edge of the chart on a Block display.
|458346| A DAQami installation/repair does not proceed until DAQami closes.
If DAQami is running during an uninstall, it will be completely uninstalled
after the next reboot.
|473375| USB-2408 Series and USB-2416 Series devices can now be configured for
single-ended or differential mode in DAQami.
|484230| With support for multiple devices added to DAQami 4.0.0, adding a device
no longer automatically creates a new configuration, so there is no longer a need
to save a configuration in this scenario.
|519476| The USB-1608HS now supports single-ended acquisitions using DAQami.
|520375| MCC devices now start a new acquisition after a system crash and reboot.
