Product Details:

NI GPIB-232CT-A is a classic RS232 to GPIB interface controller, and this gpib serial converter converts standard RS232 serial signals and GPIB bus signals bidirectionally for legacy test and measurement systems. It can turn any terminal, laptop or industrial computer with an RS232 port into a complete IEEE 488.2 GPIB controller, and it also allows standalone RS232 instruments to be integrated into an existing GPIB instrument network. It is widely deployed in calibration laboratories, old automatic test benches, production line instrument verification, maintenance workshops for electronic test equipment and portable field measurement systems. Engineers can work with NI-488.2 driver, LabVIEW and NI TestStand to build test sequences, or send direct low-level serial commands to operate the device without full driver dependency, which brings great flexibility for legacy instrument linking.

Key specifications and parameters: Built-in NAT4882 ASIC chip to implement full IEEE 488.2 protocol functions, supporting talker, listener and system controller roles on the GPIB bus. The serial port adopts standard 9-pin D-Sub RS232 interface, supports configurable baud rate, data bits, stop bits and parity settings, with hardware handshaking to avoid data loss. GPIB side uses standard 24-pin IEEE488 connector, users can set GPIB primary address and working mode through onboard DIP switches. It supports two main working modes: S mode for the serial host to control GPIB instruments, and G mode for RS232 devices to act as GPIB bus devices. The power supply has AC and DC versions for selection, AC version input 100–240 VAC, typical power consumption below 5 VA. The operating temperature range is 0 ℃ to 40 ℃, storage temperature -20 ℃ to 70 ℃, humidity 10%–90% non-condensing. Compact lightweight structure is convenient for desktop placement and portable test setup. LED indicators show power status and bus communication activity for quick troubleshooting.

This instrument interface controller is an end-of-life legacy NI hardware. We supply fully inspected and tested refurbished units for replacement and reconstruction of outdated GPIB test systems. It is compatible with traditional GPIB instruments including oscilloscopes, signal generators, power supplies, multimeters and spectrum analyzers. It is widely used in metrology calibration, military product testing, semiconductor equipment maintenance and university measurement labs. As a reliable gpib serial converter, it solves the connection problem between modern serial hosts and old GPIB instruments.
