The standard IEEE 488.1 three-wire handshake, shown in Figure S1, requires the listener to unassert NRFD, the talker to assert the DAV signal to indicate to the listener that a data byte is available and the listener to unassert the NDAC signal when it has accepted that byte.
To enable the high speed handshake, the talker pulses the NRFD signal line after the controller addresses all listeners.
The listener may assert NDAC to temporarily prevent more bytes from being transmitted or assert NRFD to force the talker to use the three-wire handshake.
