AE U3H External Parameter Box Instructions

AE U3H External Parameter Box

Product Information

Specifications

• Product Name: External Parameter Box
• Input Voltage Range: +/-10V
• Enabled Channels: 1 to 4
• Compatibility: U3H chassis and AE acquisition card

Product Usage Instructions

Connection Setup
Connect the external sensor analog voltage output to the EXT_PARA box. Ensure the input voltage does not exceed the range of +/-10V to prevent board damage. Use only channels 1 to 4 for connection.

Hardware Setup
Insert the EX_PARA Box into the acquisition card’s External card socket of the U3H chassis. Verify that the AE acquisition card with the EX_PARA BOX is the first card in the chassis with NUM set to 00.

Software Configuration

1. Open the U3H software and turn on the U3H chassis.
2. Access Hardware and Sample, then select Sample Settings.
3. In Sample Settings, navigate to Feature, click Refresh at the bottom right to detect channels, and select channels 1 to 4.
4. In Ex-Parameter Setup, enable external card acquisition.

Data Display Setup

1. Open View and choose Data Table view.
2. Select More Data, tick External Parametrics1, and click OK.
3. The external parameter #1 will appear as a new column in the Data Table.

FAQs

• Q: What should I do if the external parameter readings are not displayed correctly?
  A: Check the hardware connections, ensure correct channel selection, and verify software settings. If issues persist, contact customer support for assistance.

External Parameter Card Setup

1. Connect the external sensor analog voltage output to the EXT_PARA box. Please note the EX_PARA BOX input voltage range is +/-10V. Please DO NOT input high voltage or high current to the EX_PARA box to avoid board damage. Although there are 8 external channels indicated on the box label, only the first 4 channels are enabled. So please make sure only use PARA 1to 4 channels. “IN” is connected to the positive voltage and “GND” refers to Ground.
2. Insert the EX_PARA Box into the acquisition card’s External card socket of the U3H chassis. The AE acquisition card with the EX_PARA BOX must be the first AE card in the chassis and the chassis “NUM” must be “00”. It should have been all setup well before delivery. Double-check these hardware setups just in case it might be accidentally bumped during delivery or unpacking.
3. Open the U3H software. After that turn on the U3H chassis (hardware). Open “Hardware and Sample” and select “Sample Settings”.
4. In the “Sample settings” >> “Hit Feature”, click the “Refresh” button at the bottom right corner of the window. After refreshing the hardware, it shows how many channels it recognizes at the bottom. Make sure to tick at least one of the channels that the EX_PARA BOX connects with (should #1-4).
5. In the “Ex-Parameter Setup” section, tick “Enable” to enable external card acquisition.
6. Open “View”. Select the “Data Table” view by clicking on the area and then select “More Data”. In the popup window, scroll down and tick the External Parametrics1 and click “OK”. The external parameter #1 will show up as a new column in the Data Table.
7. In our test, the external parameter #1’s initial reading was 0.21V. When there was a 6.34V applied to the external parameter box PARA1, it was reading 6.34V.
