【英文介绍】
The NI PXI-8423/2 (Part number: 777737-02) is an RS-485 interface for PXI with 64B FIFO, 460.8 (kb/s) transfer rate and optical isolation. It is an asynchronous interface for communicating with instruments via serial ports. This model has plug-and-play compatibility with Microsoft 2000, NT, XP, Me, and 9x. Therefore, it brings the advantage of automatic configuration for worry-free installation. The device can be easily installed from the user's current application (such as Visual Basic, Excel Visual, C++, etc.) as a standard serial port.
This model is available in 2-port and 4-port configurations. In the 2-port configuration DB-9, the male connector is combined with the standard pin arrangement of the RS232 and RS485 connectors. The 4-port version of the NI PXI-8423 comes with a modular 10-bit telephone jack. However, these phone jacks can be converted to DB-25 or DB-9 male connectors with converter cables that can be purchased separately.
The NI PXI-8423/2 offers advanced features such as universal PCI, flexible baud rates up to 2 Mb/ s, and multi-processor and hyper-threading compatibility. Using this model, users will be able to communicate with devices operating at standard baud rates within 0.01%. In addition, it allows communication with devices operating at non-standard baud rates in the range of 57 b/s to 2 Mb/s. For greater efficiency and increased speed, the PXI-8423/2's hyper-threading and multiprocessor compatibility enables users to take advantage of the latest PC technologies. This interface device provides an enhanced serial driver for easy configuration, advanced performance and access to all advanced transceiver control modes.
