Board Interfaces GPIB To RS-232/-422/-485 November 24, 2008
For interfacing RS-422 or RS-485 devices to the GPIB bus, the Model 4808 interface board provides an IEEE-488.2-compliant GPIB-to-serial data path and includes an RS-232 to RS-485 converter that provides a transparent RS-232 communication path to the serial device. The board combines a GPIB interface and an RS-232 interface to control a serial device with RS-422 or RS-485 differential signals. It provides three operating modes to handle virtually any kind of serial device. Asynchronous mode is for devices like transducers and Smart mode adds the ability for the internal serial device, which may be a microcontroller or an embedded computer, to communicate with the board. Pricing starts at $ 340 each. ICS ELECTRONICS, Pleasanton, CA. (925) 416-1000.
