Section Three GPIB-PC Functions — Introduction
©National Instruments Corp. 3-13 GPIB-PC User Manual
IBSRE (bd,v)
IBSRE uses the board to set or clear the GPIB Remote Enable (REN)
line.
IBGTS (bd,v)
IBGTS causes the board to go from Active Controller to Standby
Controller, and in so doing to turn the ATN signal off. This function is
generally used to allow two external devices to talk to each other
directly. The board can selectively participate in the handshake of the
data transfer and hold off the handshake when the END message is
detected. The board may then take control synchronously without
corrupting the transfer.
IBCAC (bd,v)
IBCAC causes the board to take control of the GPIB by setting ATN and
going from Standby to Active Controller. The board can take control
synchronously or asynchronously.
IBRPP (bd,buf)
IBRPP conducts a parallel poll and returns the result.
IBPPC (bd,v)
IBPPC remotely configures or unconfigures the devices for parallel
polls.
