INSTALLATION GUIDE SCXI™-1349 SHIELDED CABLE ADAPTER This guide describes how to connect an SCXI system using the SCXI-1349 shielded cable adapter. Introduction Using the SCXI-1349, you can connect an SCXI system to your data acquisition (DAQ) device. The SCXI-1349 connects any 68-pin E Series DAQ device, excluding 61XXE devices, to any SCXI module, excluding SCXI switch modules. The SCXI-1349 is a connector assembly with three connectors: • A 68-pin male connector on the front panel of the adapter • A 50-pin male breakout connector on the printed-circuit board of the adapter • A 50-pin bracket-mounted female connector on the rear of the adapter All three connectors are shown in Figure 1.

Safety Information Cautions Do not operate the device in an explosive atmosphere or where there may be flammable gases or fumes. Do not operate damaged equipment. The safety protection features built into this device can become impaired if the device becomes damaged in any way. If the device is damaged, turn the device off and do not use it until service-trained personnel can check its safety. If necessary, return the device to National Instruments for service and repair to ensure that its safety is not compromised. Do not operate this equipment in a manner that contradicts the information specified in this document. Misuse of this equipment could result in a shock hazard. Do not substitute parts or modify equipment. Because of the danger of introducing additional hazards, do not install unauthorized parts or modify the device. Return the device to National Instruments for service and repair to ensure that its safety features are not compromised. You must insulate all of your signal connections to the highest voltage with which the SCXI-1349 can come in contact. Connections, including power signals to ground and vice versa, that exceed any of the maximum signal ratings on the SCXI device can create a shock or fire hazard, or can damage any or all of the boards connected to the SCXI chassis, the host computer, and the SCXI device. National Instruments is not liable for any damages or injuries resulting from incorrect signal connections. © National Instruments Corporation 3 SCXI-1349 Shielded Cable Adapter Clean the cable adapter by brushing off light dust with a soft non-metallic brush. Remove other contaminants with a stiff non-metallic brush. The unit must be completely dry and free from contaminants before returning it to service. The cable adapter must be used with a UL-listed SCXI chassis. Installing Modules in Your SCXI Chassis Follow these steps to prepare the chassis for integration into the system while referring to Figure 2 and 3: 1. Turn the power off and unplug the SCXI chassis. 2. Install the SCXI modules into the chassis—refer to your module/chassis documentation for instructions. 3. Within the SCXI chassis, identify the appropriate SCXI module to connect to the cable adapter. Refer to the SCXI Quick Start Guide to determine the appropriate module. 4. Insert the 50-pin female connection on the rear of the SCXI-1349 into the 50-pin male connector on the rear of the appropriate SCXI module. 5. Using the two screws provided with the SCXI-1349 chassis adapter, fasten the adapter to the rear of the SCXI chassis. 6. Connect either end of the 68-pin shielded cable to the SCXI-1349 adapter.
