Features:

Fully compatible with IEEE 488.2

256 KB RAM buffer

8 RS-232 or RS-485 data transfer rates up to 38.4 kb/s

The National Instruments GPIB RS-232/485 IEEE 488 Controller and Converter can turn any computer or terminal with an RS-232 or RS-485 port into a fully functional IEEE 488.2 controller. With the flip of the switch, the NI GPIB-232CT-A or NI GPIB-485CT-A can display any RS-232 or RS-485 device as A GPIB device. These small size controllers make them ideal for working with laptops or other computers that don't have an available internal I/O slot.

The NAT4882 IEEE 488.2 ASIC implements the full range of GPIB controller functions, including required controller functions, and is recommended by IEEE 488.2. All GPIB sequences and operations comply with IEEE 488.2 standards. External DIP switch Sets the operating mode, GPIB primary address, and serial port parameters. Depending on the version, the GPIB-232CT-A and GPIB-485CT-A controllers can accept AC or DC power input. You can connect the GPIB-232CT-A or GPIB-485CT-A up to 14 GPIB instruments.

NI GPIB-232CV-A (part number 776669-01, 776669-02, 776669-03, 776669-04, 776669-05, 776669-06, 776898-01, and 776898-31) is A GPIB to RS-232 converter. The model transparently converts data between two ports (GPIB and serial port) without special command or control code. The GPIB-232CV-A integrates a 256 KB RAM buffer and DMA to help improve the overall efficiency of the interface system. This buffer keeps the host uninstalled during plotter and printer applications. The device's RS232 data transfer rate is up to 38.4kb/s. The NI GPIB-232CV-A has a compact construction with power switches and indicators on the front panel and ports on the back panel.

This GPIB-to-RS232 converter can be used with almost any PC. With this model, users can connect the GPIB controller to any instrument that supports RS-232. In addition, users can connect IEEE 488 (GPIB) devices to any compatible PC or laptop via a computer serial port. The National Instruments GPIB-232CV-A converter allows users to connect A GPIB spectrum analyzer to a PC that supports serial ports, or can be used to connect a serial device (with an RS-232 port), such as a plotter or printer, to a GPIB network.

With this model, users can transfer data in either direction. The device is available in two versions: AC and DC. Like other models in the family, the NI GPIB-232CV-A can be configured to operate in controller mode or device mode. In device mode, the device will act as a slave device under another GPIB controller. However, in controller mode, the GPIB 232CV A operates as a GPIB controller, instructing individual GPIB devices to listen or talk.

The NI device weighs 12 ounces. The DC version measures 3.0 x 1.7 x 4.7 inches. Physical size, while the AC version's physical size: 3.0 x 1.1 x 4.7 inches. The recommended operating and storage temperature ranges for the converter are 10 to 40 °C and 0 to 70 °C, respectively.
