● Combines IEEE-488.2 responses and a smart GPIB-to-serial conversion path in one unit. Adds an IEEE-488.2 compatible GPIB interface to any RS-232 or RS-422/485 serial device. ● Provides all IEEE-488.2 functions and the Status Reporting Structure. Easiest way to add IEEE-488.2 capability to any serial device. ● Smart transparent serial data up to 57.6 Kbaud. Does not require escape sequences or a second GPIB address. ● SCPI commands set serial configuration, GPIB address and IDN message. Easy setup customizes the 4816 for the application. ● Operates on 5 to 15 Volts. Works from almost any DC power source. ● Includes Diagnostic LEDs. Provides visual indication of unit's operation, address, and selftest status. ● Support includes menu driven configuration program and GPIBkybd. The easy way to configure the interface or use the programs as examples.
ICS GPIP-to-Serial Interface Board 4816 is a smart IEEE-488.2 compatible, GPIB <-> Serial Interface that can be used to adapt devices with RS-232 and RS-422 or RS-485 serial interfaces to the GPIB Bus. The ICS GPIP-to-Serial Interface Board 4816 provides an IEEE-488.2 compliant, GPIB-to-serial conversion path between the GPIB Bus and the serial device. The 4816's serial interface can be set for any standard baud rate up to 57.6 kbaud, for the common asynchronous data formats and for RS-232, RS-422 or RS-485 signals. All configuration settings are user setable and are saved in the 4816's EEPROM memory. The ICS GPIP-to-Serial Interface Board 4816 is designed to be mounted in a test chassis or as part of a larger system.
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.
Provides RS-232C single ended or RS-485 (RS-422) differential signals on a DB-25S connector and header. Pin assignments conform to EIA RS-530 specification and are pin compatible with most RS-232 devices. Signal selection by internal jumpers.
Baud Rates
50 to 57.600 baud std, Closest integer rate for nonstandard rates.
