The MicroDaq-2 is a development of the well established MicroDaq system. The Microdaq is a single box solution providing an ultra-miniature multi-point pressure scanning unit that outputs engineering unit data over Ethernet and CAN but now comes with the additional features of IEEE 1588 PTPV2 time stamping and an embedded web server for setup.

The MicroDaq 2 is a further development of the well established MicroDaq system. The MicroDaq 2 is available alongside the existing MicroDaq and continues to provide an ultra-miniature complete pressure scanning unit that outputs engineering unit data over Ethernet and CAN.

The MicroDaq 2 features a new processor which has a hardware implementation of the IEEE 15888 PTPV2 precision time stamping protocol. The new MicroDaq also has an embedded web server for all setup functions so the serial setup program is no longer required. This also means that there is now no external USB connector on the MicroDaq 2.

The MicroDaq 2 remains fully compatible in run mode with the MicroDaq so it will run on existing code without any changes. The MicroDaq 2 contains a PSI ESP™ pressure scanner with which it interfaces, providing the user
with a straight-forward digital interface.

Where available, the MicroDaq takes full advantage of the DTC technology within the scanners. The DTC scanners contain all their coefficients in an EEPROM and the temperature of every transducer is measured to calculate the compensation. The DTC scanners also contain a 3X deranging option and shuttle valve position sense and all these functions can be accessed by the supplied software. The MicroDaq 2 may also be used with conventional scanners and provides the user with a scanner temperature measurement so that thermal mapping of the scanner can be carried out using the supplied software.

The MicroDaq 2 can scan at the maximum speed of the new Gen2 scanners (70KHz) enabling it to produce data at more than 4KHz per channel. The data is available over Ethernet which is auto-negotiating 10 / 100Mbit. The Ethernet can
be confi gured as TCP or UPD and when in UPD it can auto-identify over the network.

The MicroDaq is packaged to enable it to withstand the harsh environments of on-car testing. It also affords the scanner some protection.
