Adding an eXRCPU to eDAQ layers
The interface for installing an eXRCPU on eDAQ layers (1-EXR-E-ADT-2) (B) and six (6) 30mm screws may be purchased separately from the eXRCPU. The interface is included in eXRCPU kits 1-EXR-E-32GB-2 and 1-EXR-E-64GB-2.
Required tools: #1 Phillips screw driver and 2.5mm ball hex driver (SO-123-1003006)
CAUTION
Failure to comply with safety requirements could result in bodily injury or damage to property. Only disassemble layers in ESD safe conditions. Install only one data processor layer on an eDAQ layer stack. Do not install an eXRCPU on the interface before installing the interface on an eDAQ layer. Interface screw holes are only accessible before the eXRCPU is installed on the interface. High retention power connectors are used, therefore eXRCPU installation and removal may require some added force.
NOTE
An eXRCPU can support eight connected eDAQ layers. Every layer in an eDAQ stack must have a unique address (set using appropriate jumpers). If not, the eDAQXR web interface may not show the connected layers.
- Remove the CPU layer from an eDAQ stack. Disassemble a stack from the top down, due to alternating screw positions in the rings.
- Install a base (A) (without a battery) under the bottom eDAQ conditioning layer using six (6) screws. An optional base kit (1-EBASE-eXRCPU-2), including six (6) 30mm screws, is sold separately.
- Make sure each layer is set with a unique address using appropriate jumpers. Make sure jumper addresses ascend from low to high (1, 2, 3...) under the eXRCPU (C). The layer with the lowest address (1) is the greatest distance from the eXRCPU. Install the eDAQ layers on the top of the stack using six (6) screws each.
- Carefully align the pins and connectors and install the interface (1-EXR-E-ADT-2) (B) on the top eDAQ conditioning layer using six (6) 30mm screws.
- Carefully align the pins and connectors and install the eXRCPU (C) on the interface (B) using eight (8) M3 8mm screws.
- Connect the eXRCPU (C) to a 8–36 Vdc power supply using the power cable (1-EXR-PWR-PT-2).
- The system is now ready for use.
NOTE
To retain the ball hex driver with the eXRCPU, install the M6 12mm screw low and center on the back of the eXRCPU.
Slide the driver under the screw and wedge the handle against the top of the lower case.
Running a simple test
-
Open the web-based interface at the default IP address 192.168.100.101. In the header, click the Setup button to navigate to the Test configuration section.
-
In the Task pane, select Setup, then click the
New button to define a new test setup. Edit the setup name and description as desired. The default name is "test_name."
-
In the Task pane, select Input channels, then click the
Add button. Select the desired inputs and click OK. New channels show in the All input channels tab of the grid.
-
Click the
Save button in the header or Task pane to save changes.
-
In the header, click the Control button to navigate to the Test and data control section. In the Task pane, Test control shows.
- To view real time data, select a check box by a name in the Channels panel. A chart for that channel shows in the Display Views panel.
-
In the Task pane, click
Start to run the test. The yellow LED flashes in the status bar of the web interface and on the unit. Real time data shows in the channel chart during the test run.
-
Click
Stop to end the test run.
- To download the SIE data file, click the file name in the Test run statistics panel.

Restoring Default Settings
Administrator profile & password
To regain administrator access:
- Power down the eXRCPU.
- Press and hold the power switch.
- When the LEDs begin to flash, quickly release the power switch.
NOTE
No other profiles or users are affected.
Network Settings
To reset the module IP address to 192.168.100.101:
- Power down the eXRCPU.
- Press and hold the power switch.
- When the LEDs flash, stay on and start flashing again, release the power switch.
NOTE
This procedure activates the Default Auto Set network and does not delete any user-defined networks.
