3. IES IPAC carrier driver must be installed properly because this driver includes the header files ipac_ h which are part of the IPAC carrier driver distribution Please refer to the IPAC carrier driver user manual in the directory path CARRIER SW 95 on the distribution media lt is very important to extract the TIP865 SW 95 SRC tar gz in the usr sre directory because otherwise the automatic build with make will fail 2 1 Build the device driver Change to the directory usr src tipo865 driver and execute the Makefile make install After successful completion the driver dynamic library tio865 so will be installed in the directory lib dll TIP865 SW 95 ONX Neutrino Device Driver Page 6 of 9 TEWS TECHNOLOGIES 2 2 Start the driver process To start the TIP865 resource manager you have to start the TEWS TECHNOLOGIES IPAC carrier driver The IPAC carrier driver detects installed TEWS IPAC modules automatically and loads the appropriate driver dynamic libraries ipac_class amp The TIP865 resource manager registers a device for each TIP865 channel 4 channels per module in the QNX Neutrinos pathname space under the following name where n specifies the overall channel number of detected TIP865 modules The devices dev t865_1 to dev t865_4 belongs the first found TIP865 the devices dev t865_5 to dev t865_8 belongs to second found TIP865 and so forth please refer to the IPAC carrier driver manual
