Table 1. POWER LED Indicators LED Color LED Pattern Indication Green Solid The NI 9145 is powered on and the connected power supply is adequate. — The NI 9145 is powered off. FPGA LED You can use the FPGA LED to help debug your application or easily retrieve application status. -
Page 3: Run Led Indicators
The NI 9145 is in operational run mode. The NI 9145 inputs and outputs are functional. Flickering The NI 9145 is in bootstrap run mode. The NI 9145 is updating firmware. Run Mode Transition The following figure shows the Run Mode transition. -
Page 4: Safe-State Outputs
In synchronized mode, each conversion cycle begins with a signal from the EtherCAT master/ scan engine. The NI 9145 procedures an error if the external cycle time is too fast for a module. NI Indcom for EtherCAT only supports synchronized mode. -
Page 5: Mounting The Device
You can also mount the NI 9145 in other orientations, on a nonmetallic surface, on a 35-mm DIN rail, on a desktop, or in a rack. Mounting the NI 9145 in these or other configurations can reduce the maximum allowable ambient temperature and can affect the typical accuracy of modules in the NI 9145. -
Page 6: Mounting Requirements
Mounting Requirements Your installation must meet the following requirements for cooling and cabling clearance. Allow 25.4 mm (1.00 in.) on the top and the bottom of the NI 9145 for air circulation, as shown in the following figure. Figure 6. NI 9145 Cooling Dimensions 25.4 mm (1.00 in.) -
Page 7: Ambient Temperature
Measure the ambient temperature at each side of the NI 9145, 63.5 mm (2.50 in.) from the side and 25.4 mm (1.00 in.) forward from the rear of the NI 9145, as shown in the following figure. Figure 8. NI 9145 Ambient Temperature Location 25.4 mm... -
Page 8: Surface Mounting Dimensions
Align the NI 9145 on the surface. Fasten the NI 9145 to the surface using the M4 or number 8 screws appropriate for the surface. Tighten the screws to a maximum torque of 1.3 N · m (11.5 lb · in.). -
Page 9: Panel Mounting Dimensions
Complete the following steps to mount the NI 9145 on a panel. Align the NI 9145 and the panel mounting plate. Fasten the panel mounting plate to the NI 9145 using the screwdriver and M4 × 23 flathead screws. NI provides these screws with the panel mounting kit. Tighten the screws to a maximum torque of 1.3 N ·... -

Page 11: Clipping The Device On A Din Rail
Fasten the DIN rail kit to the NI 9145 using the screwdriver and M4 × 25 flathead screws. NI provides these screws with the DIN rail mounting kit. Tighten the screws to a maximum torque of 1.3 N · m (11.5 lb · in.). -
Page 12: Desktop Mounting Dimensions
Complete the following steps to mount the NI 9145 on a desktop. Use the Phillips #1 screwdriver to remove the two screws from the back of the NI 9145. Use the screwdriver and the M3 × 20 flathead screws to attach the adapter bracket to the NI 9145. -
Page 13: Mounting The Ni 9145 Using The Adapter Kit
Upgrading from the NI 9144 to the NI 9145 You can use the NI 9144 to NI 9145 adapter panel mounting kit (NI part number 785984-01) to mount the NI 9145 to an existing NI 9144 panel mounting plate. Contact NI for information about ordering a NI 9144 to NI 9145 adapter panel mounting kit. - Page 14 Fasten the adapter mounting plate to the NI 9144 panel mounting plate using the M4 or number 8 flathead screws. Figure 13. Attaching the Adapter Mounting Plate to the NI 9144 Panel Mounting Plate Align the NI 9145 chassis to the adapter mounting plate and fasten it using the M4 x 23 mm screws. Note You must use the screws included in the kit because they are the correct depth and thread for the chassis and the adapter mounting plate.
