  • Page 7: Overview

    1689-9640 Overview The optional Digibridge IEEE-488.2 interface board provides IEEE-488.2 (GPIB) and RS-232 Serial interfaces to the Digibridge 1689/1693 series instruments via 24-pin GPIB and 9-pin male serial connectors. The interface can be used to connect directly to a controller or to a bus comprising of multiple instruments and a controller.

  • Page 8: Gpib Address Dip Switch

    1689-9640 GPIB Address DIP Switch The GPIB Address of the Digibridge is set by the SW2 DIP Switch. The numeric value is set by setting the switch on or off for the corresponding bit with the OFF position for binary 1 and ON position for binary 0.

  • Page 9: Jumpers

    1689-9640 Jumpers The Digibridge IEEE-488.2 interface board has three jumpers, JP1, JP2, and JP3. For normal operation, all three jumpers should be open (no shorting blocks inserted). JP1 enables the RS-232 interface driver auto power off. JP2 forces firmware update mode via RS-232 serial interface. If JP2 is set, the board will be forced to await firmware update and the Digibridge will be held in reset state.
