● Provides GPIB-to-serial and serial-to-serial data paths for serial devices. Adds a GPIB interface to any RS-232 serial device and maintains serial I/O. ● Provides all IEEE-488.2 functions and the Status Reporting Structure. Easiest way to add IEEE-488.2 capability to any serial device. ● Smart firmware passes GPIB data to serial device. Does not require escape sequences or a second GPIB address. ● SCPI commands set serial configuration, GPIB address and IDN message. Easy setup customizes the 4806 for the end product. ● Mounts directly to host chassis's rear panel. Easy installation eliminates extra cables and reduces cost. ● Smart mode communicates with the internal serial device. Operates as the front end for embedded controllers. ● Includes menu driven configuration program. The easy way to configure the interface.
The Model 4806 GPIB <-> Serial Interface is a small, low cost interface board that interfaces RS-232 devices to the GPIB bus. The ICS GPIB-to-Serial Interface Board 4806 provides a smart IEEE-488.2 compliant, GPIB-to-serial conversion path and at the same time provides a serial connector that brings the existing RS-232 serial communications path out to the rear panel. The ICS GPIB-to-Serial Interface Board 4806's GPIB-to-serial data path can be set for any standard baud rate up to 57.6 kbaud and for all of the common asynchronous data formats. All configuration settings are user setable and are saved in the 4806's flash memory. The 4806 is typically mounted to the rear panel of the host chassis so the connectors can protrude through the rear panel or inside the host chassis. An on-card regulator lets the ICS GPIB-to-Serial Interface Board 4806 run on regulated or unregulated DC power.
Typical applications are adding a GPIB interface to a sensor or instrument that has a serial interface or adding an IEEE-488.2 interface to an embedded computer board.
Bus drivers incorporate power up/down protection to prevent glitching the bus during power turn-on.
Address Capability
Primary addresses 0-30 set by GPIB bus command. Address displayed on LED indicators at power turn-on.
SRQ Generation
SRQs are generated per the IEEE-488.2 specification when the unit is not addressed to talk and an enabled bit in the ESR, Questionable or Conditional register becomes set.
Serial signals conform to EIA Specifications for RS-232 signals. External connector is a DTE type interface with DTR and RTS signals pulled to +V. Internal connector is a DCE/DTE type interface with DSR and DCD signals pulled to +V.
