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-232CT-A with full GPIB controller functionality (Part number: 776668-01, 776668-02, 776668-03, 776668-04, 776668-05, 776668-06, 776899-01, 776899-31, 776667-01, 776667-02, 776667-03, 776667-04, 776667-05, 776667-06, 7769-01, and 7769-31) provide a serial port (RS232) for PCS, which is a way to talk, listen, and control on GPIB. In addition, the device can be used to quickly connect peripherals and other measurement devices to GPIB.

The National Instruments GPIB-232CT-A is available in two AC versions (100-120 VAC, 220-240 VAC) and one DC version. For the DC version, the device comes with an external power supply. This model is equipped with the NAT4882 controller chip. The chip enables NI GPIB-232CT-A to be fully compatible with IEEE 488.2 standard. To talk, listen, and control on the GPIB, users can connect the computer's serial port to the device's RS-232 port.

The RS-232 serial port can operate in S mode or G mode. In its default configuration, the device is configured to run in S mode. However, the user can change the operation method of the serial port through the DIP switch. In S mode, the connected computer acts as the control device. However, in G mode, the GPIB-232CT-A is used as an RS-232 device as a listener/speaker interface.

Each GPIB-232CT-A device can be used with the NI-488.2 driver software, A comprehensive set of drivers and programs for converting Windows-based Microsoft PCS into GPIB controllers with full bus management and communication capabilities. The GPIB serial controller has all the logic and software needed to implement the electrical and physical specifications of RS-232 and IEEE 488.
