Page 7: Installation Of The Instrument
The power for the microQDVP comes from a standard microDAQ power cable Pneumatic Interconnection The SMC™ pneumatic fittings on the back of the microQDVP accept standard 4mm OD polyurethane tubing. To connect to these: 1, Remove the knurled collar from the fitting. - Page 8 The microQDVP is controlled from one of three possible communications channels – RS232, Ethernet or CAN. If Ethernet or CAN are used then the microQDVP should be setup with an appropriate IP address and.or CANId and message protocol (in the same manner as the microDAQ).
- Page 9 The microQDVPSetup program is used in the same way as the main setup program for the microDAQ and is provided purely to set the necessary TCP and CAN parameters to enable a client program to connect with the microQDVP in run mode and issue user commands to control the unit accordingly.
- Page 10 CAN peripheral clock runs at 60Mhz. All register values should be calculated based on that clock frequency. 'CAN Base Message ID’ The microQDVP uses standard CAN message arbitration id's, and the unit is assigned the most significant 2 digits of the Hex base address. ‘CAN RX ID Offset’...
