The National Instruments GPIB-RS232 is a high-performance serial-to-GPIB interface. It transforms a computer with an RS232 serial port into a talker, listener, or controller on the GPIB bus. The NI GPIB-RS232 can also interface RS232 instruments and peripherals to the GPIB bus. The GPIB-RS232 has all the software and logic required to implement the physical and electrical specifications of the IEEE 488 and RS232 standards. It can interpret and execute high-level commands sent to it over the serial port, performing RS232-to-GPIB protocol conversions, as well as interpret commands sent over the GPIB, performing GPIB-to-RS232 protocol conversions. The GPIB-RS232 uses the NI TNT5004 controller chip, which implements all IEEE 488 talker/listener/controller functionality.
