Centronix
The logic analyzer interfaces with Centronix (parallel printer) communication lines
through a standard 25 pin D connector. The logic analyzer is compatible with
Centronix protocol. BUSY is used to indicate when data can be transfered from the
logic analyzer to the printer. DATASTROBE is used to synchronize data
transmissions. Pin outs of the Centronix connector are listed in the following table.
