eDAQXR EXRCPU getting started

Overview

The EXRCPU is a sealed, stand-alone, microprocessor-based data acquisition system designed for portable data collection in the harshest of environments. It has leading-edge signal conditioning and a capacity to perform a broad range of on-board data processing. Engineered to be rugged and mobile, the EXRCPU is tested to operate under demanding environmental conditions encompassing wide range thermal variations, resilience to significant vibration and shock loading and EMI immunity. Internal back-up capacitors protect the EXRCPU from unplanned power losses or low voltage events. Hundreds of synchronous channels are possible in a single system with virtually limitless channel counts when networking multiple systems using Ethernet communications.

The EXRCPU hosts its own secure web interface for intuitive and easy to use test setup, control, monitoring and data visualization interfaces. This server based interface supports multiple users (clients), and the capability to define and apply system access / control restrictions on a per user basis. The EXRCPU communicates through standard 100/1000 Base-T Ethernet using IPv4 or IPv6.

The EXRCPU provides direct data sourcing for three CAN buses, one GPS module, and two digital inputs that can be used with switch controls. Three digital output lines are available to drive LEDs, relays, etc. Two GB PTPv2 compatible GB Ethernet connection ports are provided for sourcing data from MXB modules and interfacing to other EXRCPU network nodes and the EX23-R. A USB port is provided to support future functional interfaces.

Four eDAQXR EXRCPU configurations are available.

Support Equipment

In addition to the EXRCPU base processor, add-on layers and included cables, set up of the system requires an adequate power supply, a support PC and any transducers or sensors needed for testing.

Power Supply

The EXRCPU is designed to always be connected to an adequate power supply for the duration of all test runs. An example of an adequate power supply is a charged nominal 12-volt vehicle battery system that reliably supplies around 13.5 volts. Additionally, an optional Somat AC Power Supply (1-E-AC/15-2) is available.

The Somat E-AC/15 Power Supply (1-E-AC/15-2) is designed to provide 15 volts DC from a standard 120-volt AC input. This power supply has been available for the SoMat eDAQ or eDAQ-lite system and may be used with the EXRCPU. The power supply connects to the 15-pin female D-SUB power connector on these units.

For more information on powering the EXRCPU, see Powering from a vehicle.

Compatible power supply cables

The EXRCPU is compatible with two power supply cables (1-EXR-PWR-PT-2 and 1-EXR-PWR-IO-PT-2). See EXRCPU pin assignments for information about cable pins.

Connecting the EXRCPU to power, network or modules

  1. Connect the 1-EXR-PWR-PT-2 power cable from the INPUT connector to a 8—36 VDC power supply.

NOTE
If a switch is not connected to the red and black wires of the remote switch cable, make sure the wires are fully insulated from each other or solidly connected to each other to prevent accidentally turning the power off. If the wires are connected to each other and there is any chance of magnetic induction, do not coil the cable in a loop.

  1. Connect the 1-KAB2106 Ethernet cable from the HOST connector to the host PC. The host PC network settings must be compatible with the main processor default IP address 192.168.100.101.
  2. Connect desired transducers to GPS and CAN ports using appropriate cables.
  3. Wait at least five seconds after supplying power to the unit.
  4. Press and release the power button. The green LED turns on. Wait about 15 seconds for the unit to boot up.
  5. Open a web browser and navigate to the default IP address 192.168.100.101. If the main processor is on a network with a DHCP server, use the HBM Device Manager (on the included USB drive) or contact your IT administrator to find out the IP address. If presented with a certificate warning, choose to proceed. The main processor web interface is displayed.

For information about navigating through the web interface, see the Interface tour.

Compatible communication cables

The EXRCPU is compatible with several communication cables (1-KAB2100-X, 1-KAB2106-X, 1-KAB2107-X, 1-SAC-TRAN-MP-X-2 and 1-SAC-EXT-MF-X-2). See Cables for information about compatible cables. Refer to the SomatXR Accessories Data Sheet, available at www.hbm.com, for a list of sensor cables for EX23-R or MX modules.

Sensors

The EXRCPU, EX23-R, MX modules, and eDAQ conditioning layers support a variety of sensors for data acquisition, including several offered directly by HBM. Contact your sales representative or visit www.hbm.com for more information.

Refer to the SomatXR Accessories Data Sheet, available at www.hbm.com, for a list of accessories and cables for EX23-R or MX modules.

Mounting options for the EXRCPU

There are 24 holes on the left, right and rear sides of the EXRCPU. Refer to the diagram for size and place. These tapped holes are available for mounting the EXRCPU apart from eDAQ layers or for mounting other devices on the EXRCPU.

EXRCPU connection options

The eDAQXR Ultra‑Rugged DAQ series is a modular and universally applicable measurement system. The layers of this family can be individually combined and intelligently connected according to the measurement task.

The main processor can be connected to supported SomatXR MXB-R modules in addition to supported legacy layers for data acquisition and SIE file storage.

The following ruggedized SomatXR MX modules are currently supported in the eDAQXR interface:
