● Adapts serial ANSI X3.28 devices to the GPIB Bus. Eliminates unprintable characters and simplifies protocol handling. ● IEEE-488.2 compatible interfaces. Responds to all IEEE-488.2 Common Commands. ● GPIB/Serial configuration set with SCPI commands and stored in Flash. Eliminates removing covers or setting switches to set or query a setting. ● User selectable singleended RS-232 and balanced RS-422/RS-485 serial signals. Matches any asynchronous serial interface. ● Support includes example programs, LabView Drivers, and menu driven Configuration Programs. Multiple programming options. ● Replaces ICS's older 4814. Smaller 4804B board provides added 488.2 functionality and firmware setup.
ICS GPIB-to-Serial Minibox 4894B-7 is a IEEE-488.2 compatible interfaces that are used to adapt serial devices that use the ANSI X3.28 protocol to the GPIB or HP-IB bus. Both interfaces provide RS-232 or RS-422/RS-485 signals at rates up to 57,600 baud. The ICS GPIB-to-Serial Minibox 4894B-7 and 4804B-7 simplify the controlling of ANSI serial devices by automatically handling the ANSI protocol and eliminating the non-printable characters. The user can program with standard ASCII characters and sees an IEEE-488.2 compatible GPIB device with the normal GPIB command-response sequence. Typical applications are interfacing Temperature Controllers or similar serial devices with the ANSI X3.28 protocol to the GPIB Bus and replacing ICS's older 4814 GPIB to Serial Interface with a modern IEEE-488.2 interface.
Bus drivers incorporate power up/down protection
to prevent glitching the bus during power
turn-on.
Address Capability
Primary addresses 0-30.
SRQ Generation
SRQs are generated per the IEEE-488.2 specifi
cation if the unit is not addressed to talk, if
SRQs are enabled and if an enabled ESR or STB
register bit occurs for:
