Product Description

The NI GPIB-RS232 is a controller manufactured by National Instruments. Its main function is to act as a communication bridge between an RS-232 serial port on a computer and a GPIB (General Purpose Interface Bus) instrument network. Essentially, this device allows you to control and communicate with GPIB-compatible test and measurement instruments using a standard serial port, which is particularly useful for modern computers that no longer include a dedicated GPIB interface.

Product Parameters

• Model Name: GPIB-RS232
• Product Type: GPIB to RS-232 Controller
• Interfaces:
  • Computer Side: RS-232 (9-pin D-sub male connector)
  • Instrument Side: GPIB (24-pin IEEE 488 connector)
• GPIB Compatibility: IEEE 488.1 and IEEE 488.2 compatible
• Baud Rate: User-configurable up to 115,200 baud
• Power Supply: External 12 VDC power supply (included)
• Firmware: The device’s functionality is managed by its internal firmware, which can be upgraded.

Product Advantages

• Legacy Integration: The primary advantage of the GPIB-RS232 is its ability to connect older GPIB instruments to modern computers that lack a dedicated GPIB port. This allows you to continue using expensive legacy equipment without needing to buy a new GPIB card.
• Cost-Effective: It provides a much more affordable way to add GPIB control to a system compared to purchasing a dedicated PCI or PXI GPIB card.
• Simple Setup: The device is designed to be a straightforward, plug-and-play solution. Its configuration is managed through simple commands sent over the serial port, making it easy to integrate into existing test setups.
• Versatility: It’s compatible with a wide range of GPIB instruments and any computer with a standard RS-232 serial port, offering a high degree of flexibility.

Precautions

• Obsolete Status: Please be aware that the NI GPIB-RS232 is an obsolete product. While it may still be available from various distributors, National Instruments no longer manufactures or provides direct support for it. For new applications, it is generally recommended to consider a modern USB or Ethernet-based GPIB controller.
• Software Compatibility: You will need to use compatible software drivers and a controller program (e.g., from NI’s software suite) on your host computer to communicate with the device.
• Power Supply: Always use the correct 12 VDC external power supply to prevent damage to the unit.
• Cabling: Ensure that both the GPIB and RS-232 cables are securely connected to prevent communication errors or signal loss.

Product Applications

The NI GPIB-RS232 is a useful tool for connecting and controlling GPIB instruments in a variety of settings, particularly where legacy equipment is in use. Its common applications include:

• Laboratory Automation: Controlling instruments like multimeters, signal generators, and oscilloscopes from a computer for automated data logging and control.
• Automated Test Systems: Integrating GPIB-based test equipment into an automated test bench for manufacturing or research and development purposes.
• Educational and Academic Use: Teaching students about data acquisition and instrument control in a hands-on environment with existing equipment.
