Enable Accept Byte

Clicking the Enable Accept Byte button prepares the analyzer to accept either GPIB data or command bytes, one byte at a time, and changes the button title to Disable Accept Byte. The analyzer unasserts NRFD and asserts NDAC. When another GPIB device on the bus asserts the DAV signal, indicating that data is available, clicking the Accept Byte button accepts the byte and prepares for the next byte. Enabling this feature disables the manual binary switches for the NRFD and NDAC control lines. When finished accepting data, clicking the Disable Accept Byte button releases control of the handshaking lines.
