SCXI -1349（部件号：182671-01）专为将 SCXI 系统连接到数据采集设备而创建。SCXI -1349 电缆适配器将 68 针 E 系列 DAQ 设备（不含 61XXE 型号）连接到 SCXI 模块（SCXI 开关模块除外）。该型号具有三个连接器。首先，在前面板上，有一个 68 针公连接器。接下来，在印刷电路板上，有一个 50 针公分线连接器。后，在适配器的背面，有一个 50 针支架安装母连接器。

美国国家仪器 SCXI-1349需要使用几件物品：一台计算机、一个 68 针 E 系列 DAQ 设备、一个 SCXI-1000、SCXI-1001 或 SCXI-1000DC 机箱、至少一个 SCXI 模块（不是 SCXI 开关模块）、一个小型一字螺丝刀、安装指南和NI SCXI-1349屏蔽电缆组件，它由电缆适配器和 68 针屏蔽电缆组成。SCXI -1349可与 1 m 或 2 m SH68-68-EP 屏蔽电缆一起使用，将 E 系列设备连接到 SCXI 机箱。其他选项是使用 0.5 m 或 1 m SHC68-68-EP 电缆或 1 m PSHR68-68 电缆将 DAQCard 连接到 SCXI 机箱。SCXI -1349 的大工作电压为 30 Vrms、42 Vpk 或 60 VDC（信号 + 共模）。

用户必须确保每个信号连接都绝缘到NI SCXI 1349可能遇到的大电压。超过National Instruments SCXI-1349 电缆适配器大信号额定值的接地电源信号和其他连接可能会导致电击或火灾危险。这也会对连接到 SCXI 机箱、计算机或 SCX 设备的电路板造成损害。

NI 设备的推荐工作温度范围为 0 至 50 °CNI SCXI-1600 (Part No.: 776572-1600) has a 16-bit ADC and is a USB data acquisition module (DAQ) for SCXI. This module is a full-function control and data module for SCXI digital I/O, switch, analog input and analog output modules. Its sampling rate is 200 kS/s. Users can install the SCXI-1600 in the instrument signal conditioning expansion (SCXI) chassis, and provide clock, calibration and external digital trigger connection for all other modules installed in the chassis. With this module, users can transform any SCXI chassis into a powerful and reliable plug-and-play data acquisition system.



NI SCXI 1600 receives analog signals from other modules and digitizes, amplifies and transmits data through USB ports. It is one of the most easily configured and calibrated devices because it has no jumpers, potentiometers or DIP switches. By connecting it to other SCXI modules, the module can collect up to 352 analog signals from RTD, thermocouple, strain gauge, current source and voltage.



NI SCXI 1600 is compatible with USB and supports power supply or hot plugging into USB ports. For time-related functions, the data acquisition module uses a powerful system timing controller called National Instruments DAQ-STC.



In order to control the analog input, DAQ-STC consists of three timing groups. The module is equipped with four LEDs on the front panel. There is a set of green LEDs for monitoring the V+and V – rails of the chassis. The other two LEDs display the active and ready status of the SCXI-1600 data acquisition module. For calibration, a special BNC connector is also provided on the front panel of the module.



NI devices run using NIDAQmx driver software, which is compatible with software package/application development environment (such as LabVIEW, LabWIndows/CVI or Measurement Studio). The recommended warm-up time is 30 minutes, and external calibration should be carried out at least once a year. The physical size of the NI device is 7.2 x 6.8 x 1.2 inches. National Instruments SCXI-1349 shielded cable adapter



SCXI - 1349 (Part No.: 182671-01) was created for connecting the SCXI system to the data acquisition equipment. The SCXI - 1349 cable adapter connects the 68-pin E-series DAQ device (excluding the 61XXE model) to the SCXI module (excluding the SCXI switch module). This model has three connectors. First, there is a 68-pin male connector on the front panel. Next, there is a 50-pin centimeter connector on the printed circuit board. Finally, on the back of the adapter, there is a 50-pin bracket to install the female connector.



The US National Instrument SCXI-1349 requires several items: a computer, a 68-pin E-series DAQ device, a SCXI-1000, SCXI-1001 or SCXI-1000DC chassis, at least one SCXI module (not the SCXI switch module), a small slotted screwdriver, installation guide and NI SCXI-1349 shielded cable assembly, which consists of cable adapter and 68-pin shielded cable. The SCXI - 1349 can be used with 1 m or 2 m SH68-68-EP shielded cable to connect the E series equipment to the SCXI chassis. The other option is to use 0.5 m or 1 m SHC68-68-EP cable or 1 m PSHR68-68 cable to connect the DAQCard to the SCXI chassis. The maximum operating voltage of SCXI - 1349 is 30 Vrms, 42 Vpk or 60 VDC (signal+common mode).



The user must ensure that each signal connection is insulated to the maximum voltage that NI SCXI 1349 may encounter. Grounding power signals and other connections that exceed the maximum signal rating of the National Instruments SCXI-1349 cable adapter may cause electric shock or fire hazard. This can also damage the circuit board connected to the SCXI chassis, computer or SCX device.



The recommended operating temperature range of NI equipment is 0 to 50 ° C, the storage temperature range is – 20 to 70 ° C, and the non-condensing relative humidity range is 10 to 90%. Its design conforms to IEC 61010-1, UL 3111-1 and CAN/CSA C22.2 No. 1010.1 of electrical measurement and test equipment. National Instruments SCXI-1346 Multi-Chassis Cable Adapter



SCXI - 1346 (Part No.: 776574-46) is suitable for applications involving multiple chassis SCXI, because it can connect them to a DAQ device. This cable adapter has two cable connections. One connection is used for the signal from the digitizer or the previous SCXI chassis, while the second connection is used to route the signal from the digitizer to the subsequent chassis. SH68-68 - EP (Part No.: 184749-01, 1 m cable; 184749-02, 2 m cable; 184749-05, 5 m cable; or 184749-10, 10 m cable) can be purchased separately and with NI SCXI 1346. This cable adapter has a mounting bracket that can be reliably connected to the SCXI chassis.



The SCXI 1346 has four connectors. The first connector is the 68-pin male connector on the front panel, which is printed with To Next Chassis. The next connector is another 68-pin male connector on the front panel, which is printed with From DAQ Board or Previous Chassis. The third connector is the 50-pin centimeter connector on the printed circuit board. The last connector is also a 50-pin connector, but it is the bracket mou
