Frequently Asked Questions

Does the MAQ20-COMx module run the ReDAQ Software or is it run externally on PC?
ReDAQ Shape is ran externally from the MAQ20 system on a host PC running Windows OS, not on the MAQ20-COMx module.

What file/formats are supported/produced with ReDAQ Shape?
Data logged in the Analyze panel in ReDAQ Shape can be exported to a .txt file or Excel file. The SD Card Logger can generate .csv files as well.

Can I disconnect my MAQ20 from my PC and have the system to continue to log data?
If you start a standard logging process (i.e. clicking "run" in ReDAQ Shape or "store" in IPEmotion), disconnecting your MAQ20 system from the PC will terminate the log.

However, if you use the MAQ20s SD Card Logger, you can start a data log and disconnect the MAQ20 and it will continue to log data until it reaches the end of the log based on the parameters you have specified (number of samples, time interval, etc.)

Is there a demo version available for ReDAQ Shape?
Yes, the version available for download from our website can serve as a demo if you do not have an unlock code. The unlicensed software will run for 30 minutes with full functionality with no license. Once the 30 minutes is up, you can restart the program to reset the 30 minute time for as many times as you would like.

Can I save the settings of my MAQ20 module to EEPROM outside of ReDAQ Shape?
Yes, refer to the address map of the module you are using which can be found at the end of that module's hardware user manual. There will be a register "Save to EEPROM." Writing the appropriate value as described in the address map to this register will save your module's current settings to EEPROM.

Is it possible to send a remote setpoint via Modbus/TCP to a PID loop running your ReDAQ Shape software on MAQ20 hardware?
Yes, it is possible to send a remote setpoint via Modbus/TCP to PID loop running in ReDAQ Shape by writing to the Modbus registers of the MAQ20 hardware. Please see the address map at the end of the MAQ20 PID Controller User Manual

On the View Analog Input/Output Channels page in ReDAQ Shape, how do I change the axis titles?
Navigate to the "Plots, Xaxis, Yaxis" section in the bottom left corner. Click either the second or third down "..." icon. This will open either the X or Y axis editor respectively. Under "Appearance" there should be a parameter "Caption". You can type a new title for the axis in the column next to the word "caption".

Can ReDAQ Shape licenses be transferred between systems?
ReDAQ Shape licenses are tied to the COM module of the system, so no, they cannot be transferred. However, projects created with a Developer license can be ran on other systems with a User license.

Can Developer unlock codes be used with the User version of ReDAQ Shape?
Each type of unlock code is only compatible with its respective software version and associated MAQ20-COM module HW. Developer unlock codes will only work with Developer version of ReDAQ Shape and User unlock codes will only work with User versions of ReDAQ Shape.

How do I get custom channel names from ReDAQ Shape to show up in my SD card log?
Applying custom channel names in ReDAQ Shape is for display purposes on the Acquire panel only, it does not change any information within the module. Because the SD card log takes place within the MAQ20-COMx module, separate from the Acquire panel, it is not possible to have your custom channel names from the Acquire panel in your SD card log.

Why am I seeing an "Unhandled Exception: Invalid Input String" error when I click on my MAQ20-COMx module in ReDAQ Shape?
This usually has to do with the display language of the host PC being set to a language other than US English. If you are experiencing this error, please try setting the display language of your PC to "English (United States)" and then see if you are still experiencing issues. If this does not fix the problem, please contact Dataforth technical support.

If I have multiple MAQ20 systems running in one instance of ReDAQ Shape, do I need an unlock code for all of them?
ALL MAQ20 systems connected to ReDAQ Shape need a valid unlock code, or else the software will stop running after 30 minutes.
